Transcriptions Romanization Ōtani Shōhei

Shohei Ohtani (Japanese: 大谷 翔平, Hepburn: Ōtani Shōhei, born July 5, 1994) is a Japanese professional baseball designated hitter and pitcher for the Los Angeles Dodgers of Major League Baseball (MLB). He is often called "Shotime" because of his amazing skills.

What makes Ohtani special is that he is a rare two-way player. This means he is excellent at both hitting (as a designated hitter) and pitching. His skills in both areas are considered some of the best in baseball history. Before joining MLB, he played in Nippon Professional Baseball (NPB) for the Hokkaido Nippon-Ham Fighters.

Ohtani was the first player picked by the Fighters in the 2012 NPB draft. He played for them from 2013 to 2017. During this time, he was both a pitcher and an outfielder. He even helped them win the 2016 Japan Series. After the 2017 season, the Fighters allowed him to join MLB. He signed with the Los Angeles Angels and quickly won the 2018 American League (AL) Rookie of the Year Award.

After some injuries in 2019 and 2020, Ohtani had an incredible year in 2021. He hit 46 home runs and struck out 156 batters. He won his first AL Most Valuable Player Award (MVP). This was a truly unique season, and he even received a special award called the Commissioner's Historic Achievement Award. In 2022, he became the first player in modern baseball to qualify for both hitting and pitching leaderboards in one season.

Ohtani won his second AL MVP award in 2023. He led the AL with 44 home runs and also won 10 games as a pitcher. He was the first player to win multiple MVP awards by a unanimous vote. He was also the first Japanese-born player to lead a league in home runs. After the 2023 season, Ohtani signed a huge 10-year, $700 million contract with the Dodgers. This was the largest contract in professional sports history at the time.

In 2024, Ohtani could not pitch because he was recovering from an elbow injury. However, he still played as a designated hitter for the Dodgers. He made history again by becoming the first MLB player to hit 50 home runs and steal 50 bases in one season. He was also unanimously named the 2024 National League MVP. He won the 2024 World Series in his first time playing in the MLB postseason.

Ohtani also plays for the Japanese national team. In the 2023 World Baseball Classic, he helped Japan win the championship. He was named the MVP of the tournament. The final game against the United States was one of the most-watched baseball games ever. Ohtani struck out his Angels teammate, Mike Trout, to win the game for Japan.

Early Life and Baseball Dreams

Shohei Ohtani was born in Mizusawa, Japan, on July 5, 1994. His mother, Kayoko, was a great badminton player in high school. His father, Toru, played amateur baseball and worked at a car factory.

Shohei is the youngest of three children. He has an older sister, Yuka, and an older brother, Ryuta, who also plays amateur baseball. In Japan, Shohei was known as a "baseball boy." This meant he loved baseball more than anything. His father coached him, and Shohei showed a talent for the game very early on. He started playing baseball in elementary school. By the time he was in seventh grade, he was already making a big impact in games.

Playing Baseball as a Teenager

As a teenager, Ohtani could have gone to any top high school baseball team in a big city. But he chose to stay in his home area, attending Hanamaki Higashi High School in Iwate. This was the same school as pitcher Yusei Kikuchi, whom Ohtani looked up to.

At Hanamaki Higashi, Ohtani's coach taught him humility by assigning him chores like cleaning toilets. In 2012, when he was 18, Ohtani threw a fastball that reached 99 mph (160 km/h). This was a new record for Japanese high school baseball at the time. He threw this pitch during the famous Summer Koshien tournament.

Professional Career in Japan

Ohtani wanted to play in Major League Baseball (MLB) right after high school. Many MLB teams were interested in him. On October 21, 2012, he announced he would try to play in MLB instead of turning professional in Japan.

However, the Hokkaido Nippon-Ham Fighters in Japan still drafted him. They knew he might not play for them. After talking with the Fighters, Ohtani decided to sign with them. He agreed to play in Japan for a few years before moving to MLB. The Fighters promised to let him be both a pitcher and a hitter. The Los Angeles Dodgers, who were Ohtani's top MLB choice, were not ready to let him play both ways. He was given jersey number 11, which was worn by famous pitcher Yu Darvish before him.

Playing for the Hokkaido Nippon-Ham Fighters (2013–2017)

Ohtani made his professional debut at age 18 on March 29, 2013. He played as a right fielder for the Fighters. He was chosen for the 2013 Pacific League All-Star team. As a pitcher, he finished his first season with 3 wins and 0 losses in 11 starts.

As a rookie, Ohtani played in the outfield and pitched. He was the first player since 1951 to be used as both a pitcher and a position player right after high school. He was also the first rookie pitcher since 1950 to bat 3rd, 4th, or 5th in the lineup. He missed some games due to an ankle sprain and a cheekbone injury.

For the season, he had 3 wins and 0 losses with a 4.23 ERA (Earned Run Average). He also hit for a .238 batting average. During his five years with the Fighters, Ohtani lived in the team dorms. His parents managed his money.

In 2014, Ohtani continued to be a two-way player. As a hitter, he batted .274 with 10 home runs. As a pitcher, he had 11 wins and 4 losses with a 2.61 ERA. He struck out 179 batters. On September 7, he became the first Japanese player to hit 10 home runs and win 10 games in the same season.

During the 2014 All-Star Game, he threw a 101 mph (162 km/h) fastball. This set a new record for the fastest pitch by a Japanese pitcher. In December, he became the second high school player in NPB history to earn 100 million yen in salary by his third year.

In 2015, Ohtani's hitting was not as strong, but his pitching was excellent. He was chosen to start the 2015 NPB All-Star Game. He finished the season with 15 wins and 5 losses, a 2.24 ERA, and 196 strikeouts. He led the Pacific League in ERA and tied for the most wins. He was named the league's top pitcher.

Ohtani also played very well for the Japanese national team in the 2015 Premier 12 tournament. He threw a 100 mph fastball. He was named the All-Star pitcher for the event and the 2015 WBSC Baseball Player of the Year.

In 2016, Ohtani had an amazing year. He hit 22 home runs and batted .322. As a pitcher, he had a career-low ERA of 1.86 with 10 wins and 4 losses. He struck out 174 batters. He won the Best Nine award as both a designated hitter and a pitcher. This made him the first player to win awards for both roles. He also won the Pacific League MVP award. He threw a fastball at 102.5 mph (165 km/h), setting a new NPB record for a Japanese player.

He led his team, Nippon Ham, to win the 2016 Japan Series. Ohtani played a big part, especially with his hitting. He batted .375 in the series.

In 2017, Ohtani played in 65 games. He batted .332 with 8 home runs. As a pitcher, he had 3 wins and 2 losses with a 3.20 ERA. In September, he announced he would move to Major League Baseball in 2018. He had surgery on his right ankle, which had been bothering him since the 2016 Japan Series.

Because he was under 25, Ohtani's signing bonus was limited. He signed with the Los Angeles Angels for a $2.315 million bonus. The Angels also paid a $20 million fee to the Fighters.

Becoming an MLB Star: The Angels (2018–2023)

On December 9, 2017, Ohtani officially signed with the Los Angeles Angels. Before the season started, the Angels said they would let him be both a hitter and a pitcher.

2018: Rookie of the Year

Ohtani pitching in 2018

Ohtani started as the designated hitter on Opening Day, March 29. He got a hit in his first at-bat. On April 1, he made his pitching debut and earned his first MLB win. On April 3, he hit his first MLB home run. He hit his third home run in three days on April 6, a first for an Angels rookie. In his second pitching start on April 8, Ohtani pitched seven scoreless innings and struck out 12 batters.

On June 8, he was placed on the injured list with an elbow sprain. He received injections to help it heal. Ohtani returned as a hitter on July 2. On August 3, he hit two home runs in one game for the first time in his career.

Ohtani finished his first MLB season batting .285 with 22 home runs, 61 RBIs, and 10 stolen bases. As a pitcher, he had 4 wins and 2 losses with a 3.31 ERA and 63 strikeouts in 10 starts. He was the second-fastest Angels rookie to hit 20 home runs. He also joined Babe Ruth as the only MLB players with 10 pitching appearances and 20 home runs in a season. He won the American League Rookie of the Month award twice.

On September 3, it was announced that Ohtani would need Tommy John surgery on his elbow. He had the surgery on October 1. On November 12, he was named the American League Rookie of the Year.

2019–2020: Injury Challenges

Ohtani batting in 2019

On May 7, 2019, Ohtani played his first game after Tommy John surgery, batting as a designated hitter. On June 13, he made history by becoming the first Japanese-born player to hit for the cycle in MLB. This means he hit a single, double, triple, and home run in the same game. His season ended early on September 12 due to another surgery on his knee. He finished the season batting .286 with 18 home runs and 62 RBIs.

The 2020 MLB season was shorter because of the COVID-19 pandemic. Ohtani returned to pitching on July 26, but he had arm discomfort after his second start. He was unable to pitch for the rest of the season. As a hitter, he batted .190 with 7 home runs. Ohtani said he felt "frustrated" and "useless" because he couldn't play as he wanted.

2021: Unanimous AL MVP

After two tough years, Ohtani worked hard to improve in the offseason. He changed his diet and trained differently. The Angels also agreed to let him play without limits, ending the special "Ohtani Rules" that restricted his playing time.

On February 8, Ohtani signed a two-year, $8.5 million contract with the Angels. On June 23, he made history by hitting for himself as a pitcher and the second batter in the lineup. This was the first time an American League team chose not to use a designated hitter while a National League team did. On July 7, he hit his 32nd home run, breaking Hideki Matsui's record for most home runs by a Japanese-born player in a season.

Ohtani was chosen as an All-Star as both a hitter and a pitcher. This was a first in MLB history. He also took part in the Home Run Derby. In the All-Star Game, he was the starting pitcher and leadoff hitter for the American League.

On July 26, Ohtani became the first pitcher in league history to have 100 strikeouts and 35 home runs before the end of July. He also earned his second American League Player of the Month award in a row.

On August 18, Ohtani hit his 40th home run, a first for a left-handed batter in Angels history. On August 28, he stole his 20th base. This made him the first Japanese-born player and first Angel to hit 40 home runs and steal 20 bases in the same season. He joined Alex Rodriguez and Ken Griffey Jr. as the only AL players to do this before September.

Ohtani finished his pitching season with 9 wins and 2 losses, a 3.18 ERA, and 156 strikeouts. As a hitter, he batted .257 with 46 home runs, 100 RBIs, 103 runs, and 26 stolen bases. He led the league in triples with eight. He became the first player in MLB history to have at least 45 homers, 25 stolen bases, 100 RBIs, 100 runs, and eight triples in a season.

Ohtani was unanimously voted the American League Most Valuable Player. This means every single voter chose him. He was also named to both the First Team and Second Team of the All-MLB Team. He won the Edgar Martínez Outstanding Designated Hitter Award and the Silver Slugger Award. He was named the Associated Press AP Athlete of the Year and many other top awards.

His 2021 season was so special that it earned him two Guinness World Records. He also received the Commissioner's Historic Achievement Award. The Prime Minister of Japan offered him a national honor, but Ohtani politely declined, saying it was "still too early."

2022: Another Great Two-Way Season

On March 22, 2022, MLB created a new rule, sometimes called the "Ohtani rule." This rule allows a pitcher who is also hitting to stay in the game as a designated hitter after they stop pitching. The Angels chose Ohtani as their Opening Day starting pitcher and leadoff hitter. He was the first player in MLB history to do both on Opening Day.

On May 9, Ohtani hit two home runs, including his first career grand slam. This was his eighth multi-homer game, passing Ichiro Suzuki for the most by a Japanese-born player. On May 14, he hit his 100th career MLB home run. He joined Babe Ruth as the only players with at least 100 home runs and 250 strikeouts as a pitcher.

On June 9, Ohtani hit a go-ahead home run and pitched seven strong innings. He helped end the Angels' 14-game losing streak. In a two-game span in June, Ohtani made history again. He became the first player in the AL or NL to have at least eight RBIs in one game and strike out at least 10 batters the next day.

On July 6, Ohtani made MLB history by becoming the first player since 1920 to record 10 strikeouts as a pitcher, two RBIs as a batter, and a stolen base all in one game. For the second year in a row, fans voted Ohtani into the All-Star Game as both a designated hitter and a starting pitcher. However, he chose to only play as a hitter in the game.

On August 9, Ohtani joined Babe Ruth in an exclusive club: 10 home runs and 10 wins in the same season. He earned his 10th win of the season and hit his 25th home run. His 118th career home run passed Ichiro Suzuki for second place on the all-time MLB home run list for Japanese-born players. He also reached 1,000 strikeouts in his career, combining his time in Japan and MLB.

The Angels signed Ohtani to a one-year, $30 million deal for the 2023 season. This was a record salary for a player in his third year of arbitration.

Ohtani finished his 2022 season with 15 wins and 9 losses, a 2.33 ERA, and 219 strikeouts. As a hitter, he batted .273 with 34 home runs, 30 doubles, 11 stolen bases, and 95 RBIs. He led the majors in how fast he ran from home plate to first base. He was named the Angels Player and Pitcher of the Year again. He also won his second straight Edgar Martínez Outstanding Designated Hitter Award. He finished second in the American League MVP voting.

2023: Second Unanimous AL MVP

After helping Japan win the 2023 World Baseball Classic, Ohtani started his second straight Opening Day for the Angels. On May 10, he struck out Jeremy Peña for his 502nd career strikeout, passing Babe Ruth on the all-time strikeout list. He also set the record for most pitching strikeouts by a player with 100 home runs.

Ohtani was named AL Player of the Week for the fifth time in his career in June. He hit six home runs, batted .435, and had 12 RBIs in seven games. He also picked up a win as a pitcher. This tied him with Ichiro Suzuki for the most Player of the Week awards by a Japanese-born player.

He won his sixth career AL Player of the Week award and third career American League Player of the Month for June. His performance in June was incredible. He batted .394 with 15 home runs and 29 RBIs. He also pitched 30⅓ innings with a 3.26 ERA.

Ohtani earned an automatic spot on the 2023 All-Star roster. He was the top vote-getter in the American League. He was also chosen as an All-Star pitcher for the third year in a row. Like in 2022, Ohtani chose to only hit in the All-Star Game due to a blister.

On July 27, Ohtani pitched his first complete-game shutout in MLB. He struck out eight batters and allowed only one hit. Later that day, he hit two home runs in the second game of a doubleheader. He earned his seventh career AL Player of the Week award and fourth career American League Player of the Month for July.

On August 19, Ohtani hit his second career grand slam and his 43rd home run. On August 23, he hit his 44th home run. However, he had to leave his pitching start early due to an elbow injury. It was later revealed that he would not pitch for the rest of 2023 or in 2024 because of a torn ligament in his right elbow. He finished his 2023 pitching season with 10 wins and 5 losses, a 3.14 ERA, and 167 strikeouts. On September 16, he was ruled out for the rest of the season due to an oblique strain. He had elbow surgery on September 19, 2023.

In 135 games as a hitter, he batted .304 with 44 home runs, 95 RBIs, and 20 stolen bases. Ohtani became the first Japanese-born player to lead a U.S. major league in home runs. He led the league in several categories, including slugging percentage and OPS.

For the second time, Ohtani was unanimously voted the American League Most Valuable Player. He was the first player in MLB history to win MVP by unanimous vote twice. He was also named to both First Teams of the All-MLB Team. He won his third straight Edgar Martínez Outstanding Designated Hitter Award, his second Silver Slugger Award, and his first Hank Aaron Award. He was named the Angels Player of the Year for the third straight year. He also won his second Associated Press AP Athlete of the Year award. Ohtani became a free agent after the 2023 season.

Joining the Dodgers and Making History (2024–present)

On December 11, 2023, Ohtani signed a 10-year, $700 million contract with the Los Angeles Dodgers. This was the largest contract in professional sports history at the time.

2024: World Series Champion and 50–50 Club

Ohtani on his way to 50 home runs and 50 stolen bases in April 2024.

Because of his elbow surgery, Ohtani did not pitch in the 2024 season. He debuted with the Dodgers as the designated hitter on March 20 in Seoul, South Korea. He hit his first home run as a Dodger on April 3. On April 21, Ohtani hit his 176th career home run, passing Hideki Matsui for the most by a Japanese player in MLB history. He hit his 200th home run on July 13.

In the All-Star Game, he hit a three-run home run. This made him the first All-Star player to have both a win on the mound (from 2021) and a home run at the plate in an All-Star Game.

On August 3, Ohtani joined the 30–30 club (30 home runs and 30 stolen bases) in just his 108th game. This was the third-fastest in MLB history. On August 23, he stole second base and hit his first career walk-off home run. This grand slam made him the fastest player to join the 40–40 club (40 home runs and 40 stolen bases). He did it in his 126th game, beating the old record by 21 games.

In his September 19 game, Ohtani set multiple MLB and Dodgers records. He had six hits, including three home runs, and 10 RBIs. He also stole two bases. He became the first and only player in MLB history to hit 50 home runs and steal 50 bases in a single season. He also became the 16th player in MLB history to have 10 or more RBIs in one game. Many people called this "one of the greatest" single-game performances ever.

On September 27, Ohtani became the first player in 23 years to reach 400 total bases in a season. The next day, he broke Ichiro's record for most stolen bases in a season by a Japanese-born player with 57. Ohtani finished the season playing in 159 games. He had a .310 batting average, a league-leading 54 home runs, 130 RBIs, and 59 stolen bases.

Ohtani made his postseason debut on October 5. He hit a game-tying three-run home run in his second at-bat. In the National League Championship Series, he performed very well. He had eight hits, two home runs, and nine walks. His 17 times reaching base and nine runs scored set new Dodgers records for a postseason series. The Dodgers won the series, sending Ohtani to his first World Series.

In Game 2 of the World Series, Ohtani injured his left shoulder sliding into second base. Despite the injury, he played in the next game. The Dodgers defeated the New York Yankees in five games, giving Ohtani his first World Series championship. After the season, it was revealed he had a torn labrum in his shoulder and needed surgery.

After the 2024 season, Ohtani won the National League Most Valuable Player award unanimously for his amazing 50–50 performance. This was his third career unanimous MVP award and his first in the National League. He became the first player in MLB history to win three unanimous MVP awards, two consecutive unanimous MVP awards, and unanimous MVP awards in both the American and National leagues. He also became the second player ever to win MVP awards in both leagues. On December 23, Ohtani won his third AP Male Athlete of the Year award, tying Michael Jordan for the second-most wins in history.

2025 Season

Ohtani started his second year with the Dodgers as the designated hitter on March 18 in Tokyo, Japan. He hit his first home run of the season on the next night. On April 2, Ohtani hit his second career walk-off home run, winning the game for the Dodgers in extra innings.

How He Plays: Pitching and Hitting

Pitching Style

Ohtani is a tall, strong right-handed pitcher. He throws a four-seam fastball that averages 97 miles per hour (156 km/h) and can reach up to 102.5 mph (165 km/h). He also throws a forkball (or split-finger fastball) that dives down, an occasional curveball, and a good slider.

He is known for throwing harder in important moments, just like some other top pitchers. Unlike most pitchers who lose speed as a game goes on, Ohtani can save his energy and power. This allows him to throw hard even late in games.

Batting and Fielding Skills

Ohtani bats left-handed. He is a designated hitter and a very powerful hitter. He can hit many home runs and often leads the league in this area.

He is also a great baserunner. He runs very fast and uses a special feet-first sliding technique. He has been a league leader in stolen bases, bunt hits, and infield hits. Scouts have timed him running from home plate to first base in as little as 3.8 seconds. In 2021, his sprint speed was among the fastest in MLB. He also had the fastest average time running from home to first base.
