Juan Martín del Potro (Spanish pronunciation: [xwan maɾˈtin del ˈpotɾo]) born 23 September 1988) is an Argentinian former professional tennis player. Del Potro's biggest achievement is winning the 2009 US Open singles title, where he defeated Rafael Nadal in the semifinals and the five-time defending champion Roger Federer in the final. He was the only man outside the Big Three (Novak Djokovic, Federer, and Nadal) to win a major between the 2005 Australian Open and the 2012 US Open, a span of 30 tournaments. Del Potro's other career highlights include reaching the 2018 US Open final, winning an Olympic bronze medal in singles at the 2012 London Olympics and the silver medal at the 2016 Rio Olympics, winning Indian Wells in 2018, and leading Argentina to the 2016 Davis Cup title. His career has been hampered by a succession of wrist and knee injuries. Del Potro first entered the top 10 of the ATP rankings on 6 October 2008. In January 2010, he reached a then-career-high ranking of world No. 4, after which he withdrew from most of the season due to an injury to his right wrist. In 2016, del Potro led Argentina to its first ever Davis Cup title by defeating Croatia's Marin Čilić in the final from two sets down. He reached his first major semifinal in four years by defeating Federer in the quarterfinals of the 2017 US Open. In 2018, he won his first Masters 1000 title at the Indian Wells Masters, defeating the defending champion and world No. 1 Federer in the final. After reaching the semifinals of the 2018 French Open, he matched his career-high ranking of No. 4, and in August 2018 he reached the world No. 3 ranking for the first time. At the 2018 US Open, he reached his second major final, where he lost to Novak Djokovic. Del Potro did not play between June 2019 and February 2022 because of pain from a knee injury, and said he would retire as a result. During his career del Potro won 22 ATP singles titles and one doubles title.

Early life

Juan Martín del Potro was born in Tandil, Argentina. His father, Daniel del Potro (1957–2021), played rugby union in Argentina and was a veterinarian. His mother, Patricia Lucas, is a teacher, and he has a younger sister named Julieta. He also had an elder sister, who died in a car accident when she was eight years old. Del Potro speaks Spanish, English and some Italian.

Aside from tennis, he enjoys playing association football and supports the Boca Juniors team in Argentina and Juventus in Italy. He would often dedicate time to both sports during his youth, and Argentine-Italian international footballer Mauro Camoranesi, who grew up in the same town, remains a close friend of del Potro.

Del Potro began playing tennis at the age of seven with coach Marcelo Gómez (who also coached Tandil-born players Juan Mónaco, Mariano Zabaleta and Máximo González). Del Potro's talent was discovered by Italian ex-tennis professional Ugo Colombini, who accompanied him through the initial phases of his young career, and is still today his agent and close friend. When questioned in 2007 about his ambitions in tennis he replied, "I dream of winning a Grand Slam and the Davis Cup." Despite refusing to participate in the Davis Cup several times, he has since achieved both goals. He is a Roman Catholic.

Tennis career

Junior years

Del Potro played his first junior match in April 2003 at the age of 14 at a Grade-2 tournament in Italy. As a junior in 2002, del Potro won the Orange Bowl 14s title, beating Marin Čilić en route to a victory over Pavel Tchekov in the final. In 2003, at the age of 14, del Potro received wildcards to three ITF Circuit events in Argentina, where he lost in straight sets in the first round of each.

As a junior, del Potro reached as high as No. 3 in the combined ITF junior world rankings, in January 2005.

2004–2005: Early career

In May 2004, del Potro won his first senior match, at the age of 15, at the ITF Circuit event in Buenos Aires by defeating Matias Niemiz. He then went on to lose in three sets to Sebastián Decoud in the second round. His next victory came over five months later against the Chilean Álvaro Loyola in a tournament in Antofagasta. Later that year, del Potro reached the quarterfinals of the ITF Circuit event in Campinas, Brazil; recording victories over Henrique Mello and Alessandro Camarço. Del Potro won two more matches before the end of the year and saw his world ranking rise from No. 1441 in August to No. 1077 in November. He also reached the finals in the Argentina Cup and Campionati Internazionali D'Italia Junior tournaments.

Del Potro reached his first final of the ITF Junior Circuit on 11 January 2005, the "Copa del Cafe (Coffee Bowl)" Junior ITF Tournament in Costa Rica, where he lost to Robin Haase in three sets. Because of the rain delays, the final set had to be played indoors; the first time the indoor courts had been used in the 44-year history of the youth tournament.

At the age of 16, del Potro reached his first senior singles final at the Futures tournament in Berimbau Naucalpan, Mexico, where he lost to Darko Mađarovski. He then went on to win consecutive titles at two Future ITF Circuit events in Santiago, Chile, including the 26th International Junior tournament. In the first tournament, he beat Jorge Aguilar, and in the second, he did not drop a set in the whole tournament and defeated Thiago Alves in the final, a player ranked more than 400 places higher at the time. He won his third title in his home country by defeating Damián Patriarca, who forfeited the match, at the ITF Circuit event in Buenos Aires.

Del Potro turned professional in June 2005 after the Italy F17 event in Bassano del Grappa, and in his first professional tournament, the Lines Trophy Challenger tournament in Reggio Emilia, he reached the semifinals, where he lost to countryman Martín Vassallo Argüello in three sets. Two tournaments later, he reached the final of the Credicard Citi MasterCard Tennis Cup in Campos do Jordão, Brazil where he lost to André Sá in straight sets. After turning 17, he won the Montevideo Challenger by defeating Boris Pašanski in the final in three sets. That same year, he failed in his first attempt to qualify for his first major, at the US Open, losing in the first round to Paraguayan Ramón Delgado. Throughout 2005, del Potro jumped over 900 positions to finish with a world ranking of No. 157, largely due to winning three Futures tournaments. He was the youngest player to finish in the year-end top 200.

2006: Top 100

In February, del Potro played his first ATP Tour event in Viña del Mar, where he defeated Albert Portas, before losing to Fernando González in the second round. Later, seeded seventh, he won the Copa Club Campestre de Aguascalientes by defeating the likes of Dick Norman and Thiago Alves, before beating Sergio Roitman in the final.

Del Potro qualified for the main draw of his first major in the 2006 French Open at the age of 17. He lost in the opening round to former French Open champion and 24th seed Juan Carlos Ferrero. Having received a wildcard, he reached the quarterfinals of the ATP event in Umag, Croatia, where he lost in three sets to the eventual champion, Stanislas Wawrinka. In Spain, he participated in the Open Castilla y León Challenger tournament held in Segovia, defeating top seed Fernando Verdasco in the quarterfinals and Benjamin Becker in the final.

Del Potro qualified for his first US Open in 2006, after being seeded ninth in the qualifying stages, where he beat Brian Vahaly, Wayne Arthurs, and Daniel Köllerer in straight sets. At the US Open, he lost in the first round to fellow qualifier Alejandro Falla of Colombia in four sets. He went on to qualify for his first ATP Masters Series tournament in Spain, the Madrid Open, where he lost in the first round to Joachim Johansson. After receiving a wild card thanks to Roger Federer, he reached the quarterfinals of the 2006 Swiss Indoors in Basel, defeating lucky loser Tobias Clemens in the first round and George Bastl in the second round, before losing to the eventual runner-up Fernando González in three sets. Del Potro finished 2006 as the youngest player in the top 100, aged 18 years, 2 months.

2007: Top 50, Davis Cup quarterfinal

Del Potro began the year by reaching his first semifinal in ATP Adelaide, Australia, where he lost to Chris Guccione, having beaten Igor Kunitsyn earlier in the day. He then reached the second round of the Australian Open, where he had to retire because of injury in his match against eventual finalist Fernando González in the fifth set. In February, del Potro played for Argentina in the first round of the Davis Cup against Austria, winning the fourth and deciding match against Jürgen Melzer in five sets, allowing Argentina to qualify for the quarterfinals.

Del Potro defeated Feliciano López before losing to eventual semifinalist Mardy Fish in the second round of the indoor Regions Morgan Keegan Championships. In his next ATP Masters event, he reached the second round of the Pacific Life Open, beating Gustavo Kuerten in the first round, but then losing to Richard Gasquet. Del Potro went further in the Miami Open, reaching the fourth round, after he defeated three top-50 players: Jonas Björkman, Marcos Baghdatis, and Mikhail Youzhny, before falling to Rafael Nadal in two sets. In May, he lost in the first round of the French Open to eventual champion Nadal.

In his first grass-court event, del Potro beat Thomas Johansson in two sets and reached the second round at the Queen's Club, where he lost to Nadal. He also reached the quarterfinals in Nottingham the following week; there he beat British qualifier Jamie Baker and Kunitsyn in the first two rounds, but lost to Ivo Karlović at the quarterfinal stage. At his inaugural Wimbledon Championships, he defeated Davide Sanguinetti in the first round, before losing to eventual champion Roger Federer in the second round, after a rain delay in the third set.

Del Potro lost to Frank Dancevic in three sets in the second round of the singles at the ATP event in Indianapolis. At the same event, partnered with Travis Parrott in doubles, he won his first doubles tournament, defeating Teymuraz Gabashvili and Karlović in the final. He regards this as a special victory, "It was fantastic to play doubles with Parrott. I'm so happy because I've never won a doubles tournament. For the rest of my life, I will remember this tournament." Del Potro qualified for the ATP Masters Series event in Cincinnati, where he reached the third round. He defeated countryman Guillermo Cañas in the first round and Philipp Kohlschreiber in the second, before losing to former world No. 1, Carlos Moyá. At that year's US Open, he defeated Nicolas Mahut and Melzer, before losing to eventual finalist and third seed Novak Djokovic in the third round. He also reached the third round of the Madrid Masters by beating Potito Starace and Tommy Robredo, before losing to eventual champion David Nalbandian, in straight sets. In the last tournament of the year, the Paris Masters, he reached the second round, where he lost to Nikolay Davydenko. That year, del Potro was the youngest player to finish in the year-end top 50 at 19 years, 2 months.

2008: First titles, Davis Cup final, top 10

Del Potro won four consecutive titles in 2008, with the final one coming in Washington.

Del Potro's first half of the season was hampered by injuries and a change of coach, starting with a first-round loss in Adelaide, where he was the seventh seed. He then made it to the second round of the Australian Open in January, only to retire against David Ferrer due to an injury. Del Potro returned to the circuit in March, winning his first match against Jesse Levine at the Miami Open, before losing in the second round to López. Struggling with injuries, his ranking fell as low as no. 81 in April. "At the start of the year, I was playing good, but I had many injuries, many problems with my body, with my physique", said del Potro. "I changed my coach, changed my physical trainer, I changed everything."

In May, del Potro had to retire again, this time in a first-round match against Andy Murray at the Rome Masters. During the second set, the Argentine allegedly made derogatory comments about Murray's mother which resulted in a complaint to the umpire. Del Potro's serve was subsequently broken three times in a row, and he suffered a back injury, which caused his retirement. In his second major of the year, the French Open, he was eliminated in the second round by Simone Bolelli in four sets. In June, he reached the semifinals of the Rosmalen Open, losing to eventual winner and top seed David Ferrer in straight sets. For the second year in a row, he was knocked out of Wimbledon in the second round; he won his first-round clash with Pavel Šnobel in straight sets, but then lost to Stanislas Wawrinka.

A successful summer followed for the Argentine. In July, del Potro and his team decided to remain in Europe to test his fitness. "We decided to play on clay courts for my back because if I start to play again on hard courts, maybe I will injure it again", he recalled. Del Potro won his first career ATP Tour title at the Mercedes Cup in Stuttgart, defeating Gasquet in straight sets in the final. A week later, del Potro reached his second career ATP Tour final at the Austrian Open in Kitzbühel, where he beat local hope and sixth seed Melzer in less than an hour, to claim his second title in two weeks. Having competed in just two clay tournaments all of the 2007 season, he never thought he would win his first two titles on clay courts.

In August, del Potro won his third consecutive title at the Los Angeles Open, beating Andy Roddick in straight sets in the final. After the match, Roddick praised his opponent. "[Del Potro] hits this way and this way kind of equally and he can hit it from inside out and running to it, which is a good thing for him, bad for the rest of us". A fourth consecutive title followed a week later in the Legg Mason Tennis Classic in Washington, D.C., where he recorded a victory over Viktor Troicki, becoming the first player in ATP history to win his first four career titles in consecutive tournaments. "I don't really understand what I did. It is difficult to believe that I have won four consecutive titles", del Potro said, crediting coach Franco Davín for his impressive run. "He changed my game. He changed my mind. He changed everything. When I play and I see him in the stands, it gives me confidence. I can play relaxed."

At the 2008 US Open, del Potro progressed to the third round, where he won his first match to five sets in the circuit against Gilles Simon to reach the round of 16. He went on to defeat Japanese teenager Kei Nishikori in straight sets. In the quarterfinals, he was stopped by eventual finalist Murray, losing after almost four hours. The defeat came after 23 consecutive victories: the second-longest winning streak in 2008 and the longest winning streak by a player outside the top 10 in the last 20 years.

Del Potro was selected to play his first home-based Davis Cup tie, between Argentina and Russia. He won his first singles match against Davydenko in three sets. He also won the fifth and deciding match against Igor Andreev in straight sets, booking Argentina a place in the final.

At the Japan Open, he made the final by defeating 11th seed Jarkko Nieminen, top seed and defending champion Ferrer, and fourth seed Richard Gasquet. He was defeated by Tomáš Berdych in the final. At the Madrid Masters, he lost in the quarterfinals in straight sets to Roger Federer. He reached the semifinals of his next tournament, the Swiss Indoors, before losing to countryman Nalbandian. He was beaten by Nalbandian again in his next tournament, this time it was in the second round of the Paris Masters. Del Potro blamed fatigue for his defeat, "It's difficult to play the last tournament of the year. I was tired, my mind was in Argentina [the venue for the Davis Cup final]". This left del Potro's qualification for the 2008 Tennis Masters Cup out of his hands, but Jo-Wilfried Tsonga beat James Blake in the semifinals, which was enough to ensure his place at the year-end event.

Del Potro won one match at the Masters Cup, against Tsonga, but lost his other two matches against the higher-ranked Djokovic and Davydenko, meaning that he exited the tournament in the round-robin stage. This was his last event of the year on the ATP Tour. He went on to lose one match in the Davis Cup final, against López, as his team succumbed to a 3–1 loss against Spain. He withdrew from his second match due to a thigh injury and was replaced by José Acasuso. Nonetheless, del Potro enjoyed a successful season; winning four titles and finishing 2008 as the youngest player in the top 10, top-ranked Argentine, and highest-ranked South American.

2009: US Open champion, ATP Tour Finals final, top 5

Del Potro began his 2009 season at the Auckland Open in New Zealand as the top seed. He defeated American Sam Querrey in the final to win the title, the fifth of his career. Seeded eighth at the Australian Open, he beat Marin Čilić in the fourth round. Del Potro's tournament ended in his next match, when he lost in straight sets to Federer. At Indian Wells, the sixth seed del Potro advanced to the quarterfinals, where he was defeated by world No. 1 Nadal. Del Potro avenged that loss the following week at the Miami Open, where he came back from a double break down in the third set at 0–3 to defeat Nadal in the quarterfinals. This was the first time del Potro had defeated Nadal in five meetings. Despite a loss in the semifinals to Murray, del Potro reached a career-high world ranking of No. 5.

In the clay-court season, del Potro was eliminated in the second round of the Monte Carlo Masters by Ivan Ljubičić. In Rome, del Potro beat Victor Troicki and Wawrinka to advance to the quarterfinals, where he was defeated by defending champion Djokovic in straight sets. This meant del Potro's head-to-head record with the Serb was now 0–3. Del Potro then played at the Madrid Masters. After defeating Murray for the first time in the quarterfinals, he lost to Federer in the semifinals. At the French Open, where he was fifth seed, del Potro defeated Michaël Llodra, Troicki, Andreev, and ninth seed Tsonga en route to the quarterfinals. He then defeated three-time former quarterfinalist Tommy Robredo to get to his first semifinal of a Grand Slam. He was defeated in a close semifinal, where he was leading by a set twice, by eventual champion Federer who, after their match, said: "[Del Potro] is young and strong, I have a lot of respect for him." Prior to this encounter, del Potro had never taken a set from Federer in their five previous career meetings.

At the 2009 Wimbledon Championships, his poor grass-court form from the past continued, as he went down to unseeded Lleyton Hewitt in the second round. In the Davis Cup quarterfinal against the Czech Republic, del Potro won his matches against Ivo Minář and Berdych in straight sets, but Argentina still lost the tie 2–3, eliminating them from the competition. A few weeks later, he defeated Hewitt and Fernando González en route to the Washington final. He successfully defended his title against top-seeded Wimbledon finalist Andy Roddick to win his second tournament of the year and become the first player since Andre Agassi to win back-to-back Washington titles. Del Potro played the following week at the Masters 1000 in Montreal, where he was seeded sixth, defeating world No. 2 Nadal in the quarterfinals, his second win in a row over Nadal. He then defeated Roddick in the semifinals, saving a match point, to advance to his first Masters 1000 final, and to improve his head-to-head record against Roddick to 3–0. In the final, he lost against Murray in three sets. He later withdrew from the next Masters 1000 event in Cincinnati due to fatigue.

Seeded sixth at the US Open, del Potro began by defeating Juan Mónaco and Jürgen Melzer in straight sets, before dropping a set but defeating Köllerer to reach the fourth round. He defeated a resurgent Juan Carlos Ferrero to advance to the quarterfinals for the second consecutive year. Del Potro then advanced to the semifinals by defeating Marin Čilić. Del Potro was down a set and a break, before winning 17 of the final 20 games to win the match. His advance to the semifinals ensured his return to the top 5 in the rankings. He then crushed world No. 3 and reigning Australian Open champion Rafael Nadal in the semifinals, to reach his first Grand Slam final. This was his third consecutive victory over Nadal and made him the first Argentine to reach a Grand Slam singles final since Mariano Puerta at the 2005 French Open. In the finals, del Potro rallied from a set and a break down to defeat world No. 1 and five-time defending champion Roger Federer in five sets; his first victory over Federer after six previous defeats, and Federer's first loss in the US Open since 2003. Del Potro stated, "Since [I was] young, I dream with this and take trophy with me", said del Potro, who became the first Argentine male to win the title since Guillermo Vilas in 1977. "I did my dream, and it's unbelievable moment. It's amazing match, amazing people. Everything is perfect." After the match, Federer praised del Potro; "I thought he hung in there and gave himself chances and, in the end, was the better man."

He is the first player since countryman David Nalbandian to defeat Federer at the US Open, and at 198 cm (6 ft 6 in), he is the tallest ever Grand Slam champion, a record he now shares with Marin Čilić, the 2014 US Open winner, and 2021 champion Daniil Medvedev. Besides Nadal and Djokovic, del Potro is the only player to defeat Federer in a Grand Slam final, and the first player to defeat both Nadal and Federer in the same Grand Slam tournament.

Dick Enberg hosted the post-match ceremony, during which a victorious del Potro requested to address his fans in Spanish. Enberg declined the request, saying that he was running out of time, but went on to list the corporate sponsored prizes del Potro won. A couple of minutes later, del Potro made the same request again, and only then did Enberg relent saying, "Very quickly, in Spanish, he wants to say hello to his friends here and in Argentina." An emotional del Potro finally spoke a few sentences in Spanish to a cheering crowd. Many viewers expressed disappointment with Enberg and broadcaster CBS over the interview. A CBS executive later defended Enberg, noting that the contract with the United States Tennis Association required that certain sponsors receive time during the ceremony. On return to his hometown Tandil, del Potro was greeted by an estimated 40,000 people.

In his first match since the US Open, del Potro was upset by world No. 189, Édouard Roger-Vasselin, in straight sets at the Japan Open in Tokyo. He then lost his second straight match to Melzer in the second round at the Masters 1000 event in Shanghai, retiring while trailing in the second set. This retirement caused concerns over the length of the tennis season. He had to retire again in the Paris Masters quarterfinals when down 0–4 to Radek Štěpánek due to an abdominal injury. In November, del Potro competed in the ATP World Tour Finals, where he lost his first round-robin match against Andy Murray, but he managed to defeat Fernando Verdasco in his second match to keep his hopes alive. After defeating Roger Federer in the following match, he qualified for the semifinals, ousting Murray by one game, the slimmest possible margin. He defeated Robin Söderling in the semifinals, before losing to Nikolay Davydenko in the final. Del Potro finished 2009 as the youngest player in the top 10, top-ranked Argentine, and highest-ranked South American for the second consecutive year.

2010: First wrist injury, out of top 250

Del Potro started his 2010 season at the AAMI Kooyong Classic in Melbourne, Australia, with a win over Croatian world No. 24 Ivan Ljubičić. On 11 January, he moved up to a career high world No. 4. He was scheduled to face Jo-Wilfried Tsonga on day 2 of the Kooyong Classic exhibition tournament, but withdrew due to a wrist injury. He came into the 2010 Australian Open with the injury not healed, and took a month off after the event, where he lost in the fourth round to Marin Čilić.

Following the Australian Open loss, del Potro missed several tournaments, including the Masters tournaments at Indian Wells and Miami, which were touted as potential return dates, due to the persistent wrist injury. Even though he withdrew from the Monte-Carlo Masters, he regained the world No. 4 ranking, due to Murray's early exit in the second round. He then withdrew from Barcelona and the Rome Masters. On 4 May, del Potro took the option of having an operation to fix the injury. On 19 May, del Potro said he would not defend his US Open title, but if all went well, he would appear after the event, targeting the Paris Masters as a possible comeback. However, on 22 July, the USTA stated that del Potro was expected to defend his US Open crown. The player himself confirmed that his comeback to the tour would be the Thailand Open and said nothing about the New York event. On 2 August, del Potro returned to the practice courts. A week before the start of the US Open, after practicing for two weeks, del Potro withdrew from the event, for he felt he was not ready to compete at the highest level.

After the nine-month break, del Potro confirmed that he would make his return at the Thailand Open. In his return match, he lost in the first round in two sets to Olivier Rochus, despite serving 16 aces. He then also played at the Japan Open, but again lost in the opening round, this time to Feliciano López.

2011: Return to tour, second Davis Cup final

Del Potro began his 2011 season at the Sydney International as a wildcard entry. In the second round, del Potro was defeated by Florian Mayer of Germany in straight sets, despite winning against sixth seed Feliciano López in three sets in the first round. His next tournament would be the first Grand Slam of the year at the 2011 Australian Open, where del Potro was defeated by 21st seed Marcos Baghdatis in the second round. As a result, del Potro slipped further down the rankings to No. 485.

After the Australian Open, he participated in the San Jose Open where he was accepted into the main draw via a protected ranking (PR). He reached the semifinals without dropping a set, however he lost to top seed Fernando Verdasco, in straight sets. Del Potro's next scheduled tournament was the U.S. National Indoor Championships, where he was accepted into the main draw via a wildcard. Here, he made his second consecutive semifinal, where he lost to top seed, world No. 8, and eventual champion Andy Roddick. To continue preparing for his first ATP Masters event since 2009, del Potro entered the Delray Beach International Tennis Championships on a wildcard. He defeated Ričardas Berankis, Teymuraz Gabashvili, Kevin Anderson and second-seeded Mardy Fish, to advance to his first ATP final since the 2009 World Tour Finals. In the final, he defeated an erratic Janko Tipsarević in two sets.

Del Potro's next tournament was the ATP Masters at the Indian Wells Masters. He reached the semifinals, where he lost to top-seeded Rafael Nadal in straight sets. Del Potro then flew to Key Biscayne, Miami to participate in the second ATP Masters of the year at the Miami Masters. Del Potro made it to the fourth round, in the third round he defeated world No. 4, Robin Söderling, in straight sets, however in the next round he lost to eventual semifinalist Mardy Fish in straight sets.

He then played at the Estoril Open, which was del Potro's first tournament on clay since he lost the 2009 Roland Garros semifinal to the eventual champion Roger Federer. In Estoril, del Potro defeated top-seeded Robin Söderling, two time-finalist in the French Open, and dropped just one set in his five matches and took the title against Fernando Verdasco in the final. After suffering an 8-millimeter tear in his left rectus abdominis, del Potro withdrew from Madrid Open and did not participate in the Internazionali BNL d'Italia, but confirmed that he would play the French Open. There he lost in the third round in four sets to second-seeded Novak Djokovic.

Del Potro reached the fourth round at Wimbledon for the first time by defeating Flavio Cipolla, Olivier Rochus, and Gilles Simon but lost in four sets to world No. 1, Rafael Nadal, a match described by The Guardian as the "battle of walking wounded". Del Potro returned to the top 20 at world No. 19 for the first time in nearly a year. His next tournament was the Los Angeles Open in late July, where he received a first-round bye as the second seed. He defeated James Blake but was defeated by Ernests Gulbis in the quarterfinals.

At the Canada Masters, seeded 16th, del Potro defeated Jarkko Nieminen before losing to Marin Čilić in the second round. At the Cincinnati Masters tournament, del Potro lost to Roger Federer, snapping the two-match winning streak he had against his rival. Del Potro entered the 2011 US Open seeded 18th. He beat Filippo Volandri and Diego Junqueira before losing to Gilles Simon in the third round.

After the US Open, del Potro played in the Davis Cup semifinal against Serbia, winning both of his rubbers against Janko Tipsarević and world No. 1, Novak Djokovic. This helped Argentina to a 3–2 victory over Serbia, booking their place in the final. In October he competed in the Stockholm Open, losing in the second round to James Blake. He then reached the final in Vienna, losing for the first time to Tsonga. Despite having won the first set, he eventually lost the final. Del Potro then reached the semifinals of the Valencia Open 500, losing to eventual champion Marcel Granollers. He then withdrew from the Paris Masters due to a shoulder injury, wiping out his chances of qualifying for the year-end championships.

Del Potro played in the Davis Cup final in Seville, with the title on the line and looking to fulfill his childhood dream. He lost in the second rubber to David Ferrer, despite being two sets to one up, eventually losing in a five-set contest in a match lasting over five hours.

Juan Martin del Potro Dubai 2014

When asked to play for Argentina in the Davis Cup, del Potro declined, arguing problems with the press and the team, and his decision to prioritize his personal career.

At the Australian Open, he won his opening match against Rhyne Williams, but lost to Roberto Bautista-Agut in the second round, having led two sets to one. Despite his second-round loss, del Potro returned to being world No. 4. After the Australian Open, del Potro required treatment for his left wrist, which has been giving him trouble since 2012.

In February, at the 2014 Rotterdam Open, he eased past Gaël Monfils and Paul-Henri Mathieu in straight sets, but fell to Latvian Ernests Gulbis in the quarterfinals. In the 2014 Dubai Tennis Championships, he retired against Somdev Devvarman after losing the first set due to his wrist injury and said "It was really tough to play today. I tried everything. I cannot be the player I would like to be.". The same injury led to his subsequent withdrawal from Masters 1000 series events in Indian Wells and Miami, meaning that del Potro dropped to world No. 8.

Del Potro underwent surgery in March 2014 to repair the problem in his left wrist, missing the rest of the 2014 season.

Del Potro began his 2015 season with wrist pain and was not sure whether he would play Sydney and the 2015 Australian Open. However, at the last minute he decided to play both tournaments. He had not played a tournament since February 2014, but he started the Sydney International with a straight-sets win against Sergiy Stakhovsky. In the second round he defeated world No. 19 and top seed Fabio Fognini to reach the quarterfinals, which he lost to Mikhail Kukushkin in two tiebreakers. Del Potro was scheduled to play Jerzy Janowicz in the first round of the 2015 Australian Open, but withdrew due to his wrist injury the day before the match and had another surgery on his left wrist. In late March Del Potro played in the Miami Open with a protected ranking and lost his first-round match to Vasek Pospisil. It would be his last match of the year, undergoing wrist surgery again in June 2015.

2016: Comeback, Olympic silver, Davis Cup champion

He defeated Jérémy Chardy in two sets in the quarterfinal, reaching his first semifinal since 2014; which he lost to eventual champion Sam Querrey. He returned to Indian Wells, competing in the first round, winning against Tim Smyczek in two sets. He lost in the next round to Tomas Berdych in straight sets. His next tournament was the Miami Open. He won his first match against countryman Guido Pella in two sets. He was set to play Roger Federer for the first time in more than two years, but just hours before the match Federer withdrew due to a stomach virus. Instead he played lucky loser and countryman Horacio Zeballos and lost in straight sets.

Del Potro then competed in his first clay-court tournament since 2013 at the BMW Open in Munich in late April. He won his first clay-court match in three years against Dustin Brown, beating him in two sets. In his second match of the tournament, he defeated Jan-Lennard Struff in his first three-set match of the year but lost to Philipp Kohlschreiber in the quarterfinals in straight sets. The next tournament he entered was the Madrid Open. He had his best victory after coming back on the tour, defeating 14th seed Dominic Thiem in straight sets but lost his next match to Jack Sock in two sets. He then competed at the Stuttgart Open, his first grass tournament since the 2013 Wimbledon Championships. He started off against Grigor Dimitrov, winning in straight sets. He then saw off John Millman in two sets. He faced fourth seed Gilles Simon in the quarterfinal, emerging victorious in three sets. In the quarterfinal he played seventh seed Kohlschreiber, who had defeated him earlier this year at the BMW Open, in Munich, and again lost in straight sets.

Juan Martín del Potro - Rio 2016
Del Potro at the 2016 Summer Olympics

He entered Wimbledon and was drawn against Frenchman Stephane Robert. He defeated Robert to set up a second-round match with fourth seed Stanislas Wawrinka, whom he defeated in four sets. Del Potro then lost in an ill-tempered four-set match against 32nd seed Lucas Pouille in the third round.

In the 2016 Olympic Games, held at the Olympic Tennis Centre in Rio de Janeiro, del Potro defeated top seed and world No. 1, Novak Djokovic, in the first round, winning two tiebreaks. It was a significant win for him because he was ranked no. 145 in the world and was coming back from an injury. He also defeated João Sousa and Taro Daniel in three sets. Next, he defeated top-20 player Bautista Agut to guarantee a medal match. He played 2008 gold medalist and the 2016 doubles gold medalist, Rafael Nadal. He defeated him in three tight sets to guarantee a medal. Del Potro played in his first gold medal match against the reigning Wimbledon champion from the previous month, Andy Murray and lost in four grueling sets in over four hours. However, del Potro said after beating Nadal "I already won silver, that's good enough for me."

At the US Open Del Potro's ranking of No. 141 was not sufficient to gain direct entry into the main draw but he was granted a wild card. He was drawn against countryman Diego Schwartzman and defeated him in straight sets. In the second round, he defeated 19th seed and top-ranked American Steve Johnson in straight sets, fighting back from a break down during the first two sets. In the third round, he faced 11th seed and Grand Slam finalist David Ferrer, and again defeated him in straight sets. In the fourth round, he faced eighth seed Dominic Thiem. After del Potro won the first set, the match ended when Thiem retired during the second set. Del Potro then lost to eventual champion Stan Wawrinka in the quarterfinals in four sets.

Del Potro then played against Murray, in a rematch of the Olympic final, in the Davis Cup semifinal, held in Glasgow. Del Potro won the thrilling five-set match in 5 hours and 7 minutes. Del Potro was granted a wildcard for the Shanghai Masters in October, where he lost in the first round in three sets to 11th seed David Goffin, despite being a set and a break up. After this, del Potro was given a wild card into the Stockholm Open. Del Potro beat John Isner, Nicolas Almagro, Ivo Karlovic, and Grigor Dimitrov on his way to the final. In the final, del Potro cruised to victory over Jack Sock to win his first title since his return from injury. Del Potro then played at the Swiss Indoors, where he comfortably beat qualifier Robin Haase in the first round. He then got revenge on Goffin in a straight sets win, before falling in two tight sets to Kei Nishikori in the quarterfinals.

Vying for Argentina's first title, del Potro played in the 2016 Davis Cup against Croatia. His first match was a four set victory against Ivo Karlović. Partnering Leonardo Mayer, del Potro lost in doubles against Ivan Dodig and Marin Čilić. 2–1 down in matches, del Potro played in singles against Čilić, coming back from two sets down for the first time in his career to win in five sets. Described as one of the best Davis Cup comebacks ever, del Potro levelled the score at 2–2, paving the way for Federico Delbonis to complete the comeback by beating Ivo Karlović, in straight sets, thus claiming Argentina's first ever Davis Cup title.

For the second time in his career, after 2011, del Potro was named ATP Comeback Player of the Year.

2017: Continued comeback, US Open semifinal

Del Potro decided to skip the 2017 Australian Open and made his season debut at the Delray Beach Open, where he was seeded in a tournament for the first time in three years, at No. 7, and won his first three matches against Kevin Anderson, Damir Dzumhur and Sam Querrey, who beat him in the semifinals of the same tournament last year. However, in the semifinals this year, del Potro lost to top seed and world No. 4 Milos Raonic in straight sets. Next, del Potro played in the Mexican Open, where he was drawn to play qualifier Frances Tiafoe, who idolised del Potro when he was a child. Del Potro won in a tight three-set match. In the next round, del Potro played the top seed of the tournament for the second time in a row. This time it was Djokovic on the other side of the court. Del Potro lost in three sets after winning the first set.

Del Potro next played at the Indian Wells Masters. He was seeded 31st so he received a bye into the second round, where he beat his Argentine Davis Cup teammate Federico Delbonis in two tight sets. In the next round, Del Potro faced Djokovic again, with the same result, Del Potro losing in three sets. After, Del Potro played at the Miami Open, where he had a comfortable victory over Robin Haase before losing to Roger Federer in straight sets. Del Potro began his clay-court season at the Estoril Open, where he beat Yuichi Sugita for the loss of just four games in the first round, but withdrew the next day after he heard that his grandfather had died. Del Potro withdrew from the Madrid Open, reappearing at the Italian Open where he reached the quarterfinals of a Masters 1000 tournament for the first time since the 2013 Paris Masters, following victories over 10th seed Grigor Dimitrov, Kyle Edmund and seventh seed Kei Nishikori, which was his first victory in 2017 over a top 10 ranked player. However, he succumbed yet again to world No. 2, Novak Djokovic, in a rain-interrupted straight sets match.

JMDP Lyon 2017
Del Potro at the 2017 Lyon Open

In May Del Potro competed at the newly formed Lyon Open, where he defeated lucky loser Quentin Halys, but lost in the next round against Portuguese qualifier Gastão Elias in straight sets. Doubt was cast over his participation at the French Open because of a back injury that had hampered him at Lyon, but he eventually decided to partake in the event. Del Potro entered the event after a five-year absence as the 29th seed, the first time since the 2014 Australian Open that he was seeded at a Grand Slam tournament. In the first round, Del Potro defeated Guido Pella in straight sets, and in the second round against Nicolás Almagro, it was one set apiece before Almagro retired. Del Potro eventually fell in straight sets to top seed Andy Murray in the third round.

After suffering a second round exit at Wimbledon in straight sets against Ernests Gulbis, Del Potro began his summer North American hardcourt season in Washington, where he lost to Kei Nishikori in the third round, ending his 15-match winning streak at the event. He then lost in two sets to Denis Shapovalov in the second round at the Canadian Open in Montreal, and at the Cincinnati Masters he won against Tomáš Berdych in the first round and qualifier Mitchell Krueger in the second before losing to eventual champion Grigor Dimitrov in the third round.

At the US Open, Del Potro defeated Henri Laaksonen, Adrián Menéndez-Maceiras and Roberto Bautista Agut in straight sets, putting his best year performance to date against Bautista Agut. He began his fourth round match against Dominic Thiem struggling, falling two sets behind. However, he then raised his level and, with the help of the crowd, eventually prevailed in five sets, saving two match points in the fourth set with two aces. In the post match interview he admitted he considered retiring from the match during the second set.

The US Open account on Instagram switched his racquet for Thor's hammer using software editing tools, which created a new nickname for the Argentine: Juan Martin "del Thortro", by fellow tennis player Roger Federer, adding to a collection of nicknames such as "Delpo", "Tower of Tandil", "Palito" (stick) and "Enano" (midget). In the quarterfinals he defeated Roger Federer in four tight sets; his second victory over the Swiss at the US Open, having beaten him in the final in 2009. By doing so he reached his first major semifinal since Wimbledon 2013. His run came to an end in four sets, losing to world No. 1, Rafael Nadal.

Del Potro began his Asian hard court swing in Beijing, where he lost in straight sets to Grigor Dimitrov in the second round, his second loss against the Bulgarian. This was followed by the Shanghai Masters, where he reached the semifinals of a Masters 1000 event for the first time since 2013 (also in Shanghai), most notably upsetting Alexander Zverev in the third round, his second triumph over a Top 5 ranked opponent after his victory over Roger Federer at the US Open. Del Potro won the first set but eventually lost in the semifinals against Federer, who would go on to win the tournament.

Del Potro defended his 2016 Stockholm Open title by defeating Grigor Dimitrov in the finals of the 2017 Stockholm Open in straight sets. This victory gave Del Potro his 20th ATP career title. He then reached the final of Basel, where he faced Federer and again lost in three sets after winning the first. Del Potro then made it to the quarterfinals of the Paris Masters, where he was one win away from entering the top 10 and qualifying for the ATP Finals, which would have been his first time since 2013 participating in the year-end tournament. However, he was defeated in three sets by John Isner and subsequently declined to be chosen as an alternate for the tournament, instead choosing to rest with his family and friends in his native Tandil. Nevertheless, Del Potro won 730 points in a span of three weeks and reached the 11th spot of the ATP rankings.

2018: First Masters, second US Open final, world No. 3, injuries

Del Potro started the season at the ASB Classic in New Zealand, where he debuted with a victory against Denis Shapovalov.

His winning streak would not stop there, however, as he went on to win the Indian Wells Open, the first Masters 1000 tournament of his career. He received a bye into the second round, where he started his successful run by defeating teenager Alex De Minaur, veteran David Ferrer, compatriot Leonardo Mayer, 31st seed Philipp Kohlschreiber and 32nd seed Milos Raonic en route to the final. There, he faced reigning champion and world No. 1, Roger Federer. Del Potro prevailed in three sets despite Federer serving for the match in the decider and holding three championship points. This was del Potro's biggest achievement in the ATP Tour after the 2009 US Open.

Del Potro continued his successful run at the Miami Open, again starting from the second round as a seeded player. He defeated Robin Haase, Kei Nishikori and Filip Krajinović, before facing off in the quarterfinals against 20th seed Milos Raonic. Del Potro managed to once again prevail in a grueling match against the Canadian, reaching the semifinals. His 15-match win streak ended as he was defeated by 14th seed and eventual champion John Isner.

Del Potro returned to the courts in early May for the clay court season, although his first results were lackluster. After starting the Madrid Open with a solid victory against Bosnian Damir Džumhur in the second round, he was upset by qualifier Dušan Lajović in three sets. In his next tournament in Rome, del Potro defeated rising star Stefanos Tsitsipas before retiring against David Goffin in the next round due to a groin injury. His participation at the French Open was in doubt but he recovered in time and entered the tournament as the fifth seed. Following victories against French players Nicolas Mahut and Julien Benneteau, he defeated 31st seed Albert Ramos Viñolas and world No. 10, John Isner, en route to a quarterfinal clash against world No. 4 and frequent rival, Marin Čilić. After an intense match, in which he had an argument with a fan who supposedly heckled him, Del Potro defeated Čilić in four sets and reached the semifinals, the first time since 2009. He then lost to ten-times French Open champion Rafael Nadal in straight sets. His run to the semifinals ensured that, for the first time since February 2014, Del Potro would return to his career-best ranking of world No. 4.

At Wimbledon, Del Potro defeated Peter Gojowczyk, Feliciano Lopez and Benoît Paire in straight sets to set up a round of 16 clash with Gilles Simon. He went on to beat Simon in four sets over two days and in nearly 4,5 hours to set up another meeting with world No. 1 Rafael Nadal, who defeated him in five sets after del Potro having led two sets to one. Del Potro then competed at the Los Cabos Open, where he reached the final but lost to second-seeded Fabio Fognini in straight sets. Del Potro was seeded third at the Rogers Cup, but withdrew due to an injury to his left wrist. Nonetheless, due to Alexander Zverev's loss in the quarterfinals, del Potro moved up to a new career-high ranking of world No. 3 as of the week of 13 August. Del Potro was seeded fourth at Cincinnati, defeating Chung Hyeon and Nick Kyrgios before falling to David Goffin in the quarterfinals.

Entering the US Open seeded third, del Potro reached the quarterfinals without dropping a set, defeating Donald Young, Denis Kudla, 31st seed Fernando Verdasco, and 20th seed Borna Ćorić. He then faced 11th seed John Isner, defeating him in four sets to reach his second consecutive US Open semifinal, where he faced top seed and defending champion Rafael Nadal in a rematch of the previous year's semifinal. Nadal retired from the match due to a knee injury after del Potro took the first two sets. With this victory, del Potro advanced to his second Grand Slam final, nine years after his 2009 US Open triumph. He was defeated by two-time champion Novak Djokovic in three straight sets.

Del Potro entered the China Open in October as the top seed. He defeated Albert Ramos Viñolas, Karen Khachanov, Filip Krajinović, and reached the final without dropping a set after Fabio Fognini withdrew before the semifinal. He faced unseeded Nikoloz Basilashvili in the final, losing in two sets. He then competed in the Shanghai Masters seeded third. He defeated Richard Gasquet and faced 13th seed Borna Ćorić in the third round, narrowly dropping the first set before he retired due to a knee injury. This injury forced his withdrawal from the rest of the season, including the ATP Finals, for which he had qualified for the first time since 2013.

2019–2021: Continued injuries

Del Potro's injury lingered into the 2019 season, forcing him to withdraw from the Australian Open. He made his comeback at the Delray Beach Open in February where he reached the quarterfinals, losing to Mackenzie McDonald in three sets. Still not having recovered from injury, Del Potro chose not to defend his titles in Acapulco and Indian Wells, withdrawing from both tournaments. Playing in his first tournament back at the Madrid Open, del Potro lost his first match to Laslo Djere. He then played in Rome and secured wins against David Goffin, who had a 3–1 lead over him before the match, and Casper Ruud. He failed to convert two match points in a second set tiebreaker to ultimately lose his quarterfinal against world No. 1 Novak Djokovic over a three-hour match.

At the 2019 French Open, del Potro was seeded eighth. After wins in the first three rounds against Nicolás Jarry, Yoshihito Nishioka and Jordan Thompson respectively he lost in the fourth round to tenth-seeded Karen Khachanov in four sets. In his first grass-court tournament of the season at Queen's Club, del Potro suffered another career-threatening injury when he fractured his kneecap in his first round match against Denis Shapovalov.

Del Potro did not play any professional tennis from June 2019 at Queen's Club until 2022 at the Argentina Open. He underwent four right knee surgeries (June 2019, January 2020, August 2020 and March 2021) and withdrew from the Tokyo Olympics in July 2021. At the 2021 US Open, del Potro reported that his knee was getting better, he had picked up training on the court again and hoped to be ready to play on the tour within a couple of months.

2022: Return to professional tennis, potential retirement

On 31 January, it was announced that Del Potro will make his return to professional tennis at the Argentina Open, where he accepted a wildcard. He also accepted a wildcard to play the Rio Open.

On 5 February, Del Potro stated in a press conference that he would likely retire after the Argentina Open. He cited ongoing knee pain due to an injury as a reason behind the potential retirement, and said that his return is "maybe more of a farewell than a comeback". Del Potro lost in the first round of the Argentina Open to Federico Delbonis, and again hinted at retirement in the post-match interview. He withdrew from the 2022 Rio Open on 11 February. Del Potro has not played any matches since; he dropped out of the singles rankings on 20 June, as well as the doubles rankings on 9 May.

2023: Failed comeback at the US Open

In March, he stated that he would begin training for a potential return at the 2023 US Open. In August, he announced that he wouldn't be able to compete in the tournament, due to his physical state.

Playing style

Juan Martín del Potro at the 2009 US Open 02
Del Potro hits a forehand.

Del Potro is an offensive baseliner with a very powerful serve and a deep, flat, topspin groundstroke, where he pushes his opponents deeper with his heavy groundstroke and trying to blast past them with a winner. His forehand is one of his main strengths and possibly the most powerful in the game, capable of frequently generating speeds more than 160 km/h. It is widely considered among the top three best forehands on tour by fellow players and analysts, alongside Roger Federer and Rafael Nadal.

Although he possessed a very consistent and powerful double-handed backhand, injury and surgeries on his wrist have rendered his backhand the main weakness in his game. Since his return in 2016, del Potro made tactical changes in his game in order to protect his wrist, like significantly reducing the pace of his two-hander and adopting a one-handed slice. Despite del Potro admitting that relying on slices is "not my game," the shot has been effective in moving his opponents out of position and slowing down rallies enough to allow him to set up powerful offensive shots with his forehand. Furthermore, to compensate for the newfound vulnerability in his backhand wing, del Potro has improved the power and accuracy of his other shots, most notably his serve.

Equipment and apparel

Del Potro used the Wilson Hyper ProStaff 6.1 Midplus Stretch early on in his career, and has continued to use this racquet under new paint jobs years later. Del Potro is very superstitious, and after suffering a wrist injury shortly after switching to the Wilson BLX Pro Tour paint job in 2010, he returned to playing with the then outdated Wilson K-Factor 6.1 95 paint job. He particularly favored the exact racquets he had used to win his only Grand Slam title at the 2009 US Open. He again refused to update his racquet to the Wilson BLX Juice Pro in 2012, and in 2014 had only a few K-Factor racquets left. He makes use of the same racket painted to resemble the Wilson ProStaff 97. For strings, he uses Luxilon ALU Power strung at 58 lbs.
