Jannik Sinner (born August 16, 2001) is a professional tennis player from Italy. He is a huge star in the tennis world. He has been ranked world No. 1 by the Association of Tennis Professionals (ATP). This means he was officially the best men's singles player in the world! He was the first Italian player ever to reach this top spot.

Sinner has won 19 big singles tournaments on the ATP Tour. This includes three Grand Slam titles. Grand Slams are the most important events in tennis. He won the 2024 Australian Open, the 2025 Australian Open, and the 2024 US Open. He also won the 2024 ATP Finals, a special tournament for the top players. Plus, he won four Masters 1000 titles, which are also very important. He helped his country, Italy, win the Davis Cup (a team competition) in 2023 and 2024.

Jannik did not have many big wins as a junior player. But he started playing in professional events when he was just 16. By age 17, he was winning titles on the ATP Challenger Tour. In 2019, he joined the top 100 players in the world. That year, he won the Next Generation ATP Finals and was named ATP Newcomer of the Year. In 2021, he won the Washington Open. He became the youngest champion of an ATP 500 event. He was also the first player born in the 2000s to reach the top 10 rankings. Jannik won his first Masters 1000 title at the 2023 Canadian Open. He finished that year by playing in the final of the ATP Finals. He also helped Italy win the Davis Cup.

At the 2024 Australian Open, Sinner had an amazing tournament. He beat the world No. 1 player, Novak Djokovic. In the final match, he beat Daniil Medvedev. He was losing by two sets but came back to win his first Grand Slam title! After that, he won three Masters 1000 tournaments, the US Open, and the ATP Finals.

It was found to be accidental. When he returned, he reached the final of the French Open. He lost a very long and exciting match to Carlos Alcaraz.

Early Life and Background

Jannik Sinner was born on August 16, 2001. He was born in Innichen, a town in South Tyrol, Northern Italy. His parents are Hanspeter and Siglinde Sinner. He grew up speaking German. His family lived in Sexten, a town in the beautiful Dolomites mountains. His dad was a chef and his mom was a waitress at a restaurant in a ski lodge. Jannik has an older brother named Mark, who was adopted from Russia.

Jannik started skiing and playing tennis when he was only three years old! He was a very good skier. He was one of Italy's best junior skiers between ages seven and twelve. He even won a national championship in giant slalom (a type of ski race) when he was seven.

When he was seven, Jannik stopped playing tennis for a year. But his dad encouraged him to start again. His first regular tennis coach was Heribert Mayr. Tennis was still his third favorite sport, after skiing and football (soccer).

When he turned 13, Jannik decided to focus only on tennis. He realized his tall, thin body might be better for tennis than skiing. He also liked that tennis was an individual sport. He could compete directly against one opponent. So, he moved by himself to Bordighera, a town on the Italian Riviera. There, he trained at the Piatti Tennis Center with famous coach Riccardo Piatti. His parents supported his decision. At first, he lived with the family of one of his coaches. Later, he shared an apartment with other young players. Before this, he had only played tennis twice a week! He also finished his schooling at a private economics school in Bolzano.

Junior Career

Before becoming a professional, young tennis players often play on the ITF Junior Circuit. This is a tour for players under 18. Jannik Sinner started playing on this circuit. However, he did not have huge success as a junior. He mostly moved to playing professional events after 2017. He never played in the main part of the biggest junior singles tournaments, called Grade 1 events. The only top-level Grade A tournament he played in was the Trofeo Bonfiglio in Italy.

He played this Italian Grade A tournament twice. He reached the quarterfinals in 2018. That was the only junior event he played that year. He never played in any of the junior Grand Slam tournaments. These include junior Wimbledon or the junior US Open. Because he did not play many high-level junior events, his highest ranking as a junior was No. 133. This is not as high as some other top professional players.

Professional Career

2018: Starting Out on Tour

Jannik started playing on the ITF Men's Circuit in early 2018. This is a level of professional tennis where players earn their first ranking points. Because his ranking was low, he mostly played in ITF Futures events. Later in the year, he started getting wild cards for ATP Challenger Tour events. Wild cards are special invitations to play in tournaments. The Challenger Tour is the next step up from Futures. It is run by the Association of Tennis Professionals (ATP). His only ITF title in 2018 was in doubles (playing with a partner). He finished the year ranked No. 551 in the world.
