Ohtani, 31, hit a grand slam during Team Japan's 13-0 win over Chinese Taipei (Taiwan) during the Pool stage of the tournament. His homer came during a historic moment in which Japan's 10 runs in the second inning were the most ever by a team in one inning in World Baseball Classic history.
The previous record high for an Ohtani jersey was a game-worn jersey signed "24 NL MVP" that sold for $249,999. Ohtani also had another jersey from the 2023 World Baseball Classic that sold for just over $126,000.
Ohtani finished the 2026 WBC with three homers and seven RBI, five of which came from the win over Chinese Taipei (Taiwan), with a .462 batting average. After Japan swept the Pool stage, going 4-0, they would lose to eventual WBC champions Venezuela during the quarter-finals.
The reigning back-to-back National League MVP is coming off back-to-back World Series wins with the Los Angeles Dodgers and has established himself as the best baseball player in the world and arguably the greatest to ever do it.
However, none of the jerseys came close to the 50-50 ball that sold for a record-breaking $4.39 million when Ohtani became the first player in MLB history to hit 50 home runs and steal 50 bases in the same season.
The Dodgers' season begins on March 26th against the Arizona Diamondbacks.
