Shohei Ohtani (大谷 翔平 (おおたに しょうへい), Ōtani Shōhei, [oːtaɲi ɕoːheː]; born July 5, 1994) is a Japanese professional baseball pitcher and designated hitter for the Los Angeles Dodgers of Major League Baseball (MLB). Nicknamed "Shotime", he has previously played in MLB for the Los Angeles Angels and the Hokkaido Nippon-Ham Fighters of Nippon Professional Baseball (NPB). Because of his elite contributions as a hitter and as a pitcher, a rarity as a two-way player, Ohtani's 2021, 2022, and 2023 seasons are considered among the greatest in baseball history, with some comparing them favorably to the early career of Babe Ruth.

Considered early on as an elite two-way player, Ohtani was the first pick of the Fighters in the 2012 draft. He played in NPB for the Fighters from 2013 through 2017 as a pitcher and an outfielder, and won the 2016 Japan Series with them. The Fighters posted Ohtani to MLB after the 2017 season, and he signed with the Angels, soon winning the 2018 American League (AL) Rookie of the Year Award.

Following an injury-plagued 2019 and 2020, Ohtani hit 46 home runs and struck out 156 batters en route to winning his first AL Most Valuable Player Award (MVP) in 2021, a statistically unprecedented two-way season that saw him bestowed with the Commissioner's Historic Achievement Award. In 2022, he became the first player in the modern era to qualify for both the hitting and pitching leaderboards in one season, finishing third in the AL with 219 strikeouts.

Ohtani won his second AL MVP in 2023, leading the AL with 44 home runs while recording 10 wins as a pitcher. He was the first player to win multiple unanimous MVPs and the first Japanese-born player to win a league home run title. After the 2023 season, Ohtani signed a 10-year, $700 million contract with the Dodgers, the largest contract in professional sports history. Unable to pitch in 2024 while recovering from a second elbow injury, Ohtani became the sixth member of the 40–40 club.

Internationally, Ohtani represents Japan. At the 2023 World Baseball Classic, he won the MVP Award for the tournament following Japan's victory over the United States. The 2023 final was one of the most-watched baseball games in history, culminating with Ohtani striking out Angels teammate and USA captain Mike Trout on a full count, securing a 3–2 win and Japan's third title.
