Expectations for Yoshinobu Yamamoto, who dominated Japanese professional baseball (NPB) before entering Major League Baseball (MLB), were incredibly high. His monumental 12-year, $325 million contract with the LA Dodgers reflected his potential. While many watched for his MLB adaptation, the 2025 season surpassed all expectations, marking a year where Yamamoto proved why he's called a 'monster pitcher.' If his 2024 debut season was a time of adjustment, 2025 was the year Yamamoto made his mark on the world.
Yoshinobu Yamamoto's MLB debut was on March 21, 2024, against the San Diego Padres. He had a tough debut, allowing 5 runs in 1 inning. However, he adapted quickly and earned his first MLB win on April 6 against the Chicago Cubs, pitching 5 scoreless innings. The 2024 season was a process of adapting to injuries, the MLB baseball, and unfamiliar rotations, but he also gained valuable experience, contributing to the Dodgers' World Series victory. This period was a crucial turning point, laying a solid foundation for his spectacular performance in 2025.
In the 2025 season, Yamamoto returned as a completely different pitcher. He started 30 regular-season games, with a record of 12 wins and 8 losses, an ERA of 2.49, and 201 strikeouts in 173.2 innings, establishing himself as the Dodgers' solid ace. Early in the season, he showed dominance, going 21 consecutive scoreless innings, lowering his ERA to 0.93. Having perfectly adapted to the MLB baseball, his splitter was called a 'magic ball,' inducing swings and misses from batters, and his diverse pitches and precise control put him among the league's top starting pitchers.
Yamamoto's true value shone even brighter in the postseason. In the 2025 National League Championship Series (NLCS) Game 2 against the Milwaukee Brewers, he led the team to victory with a 9-inning, 1-run complete game. He then showcased an incredible performance in Game 2 of the World Series against the Toronto Blue Jays, with a 9-inning, 4-hit, 8-strikeout, 1-run complete game. This marked the first time in 24 years since Curt Schilling in 2001 that a pitcher had two consecutive complete games in the MLB postseason, and the first for a Dodgers player in 37 years, since Orel Hershiser in 1988. He also pitched 6 innings allowing 1 run in Game 6 of the World Series, saving the team from the brink of elimination and leading to Game 7, thus becoming a true hero of 'autumn baseball'.
Yamamoto throws a four-seam fastball averaging over 95 mph, along with a cutter, splitter, curveball, slider, and sinker, displaying versatility. His splitter, in particular, is considered a decisive pitch that perfectly steals the timing of the batters, and the quality of all his pitches is rated above the MLB average. Furthermore, despite his small stature, his excellent physical flexibility and elasticity, and his outstanding fielding skills derived from his experience as an infielder in his younger days are his other strengths. Above all, his calm control and outstanding crisis management skills that do not falter at crucial moments, and even his humility of cleaning up the dugout after the game, show him as a 'complete pitcher' who combines skill and character.
Yamamoto's performance in the 2025 season showed his potential to grow beyond just the Dodgers' ace and become a representative pitcher of the entire MLB. His excellent adaptation to the baseball, diverse pitches, and strong performance in big games make him a strong candidate for the Cy Young Award. Pitching coach Mark Prior praised his thorough self-management and preparation, and mentioned that the Dodgers' fate depends on Yamamoto's shoulders. The attention of baseball fans worldwide is focused on what records Yamamoto will leave in MLB history.
Yoshinobu Yamamoto's 2025 season was a true 'debut season' and an 'explosive season' for him. Building on the adjustment period of 2024, he proved his value perfectly by showing an overwhelming performance in the 2025 regular season and postseason. His historic complete game streak and near-perfect pitching are heralding the beginning of a new 'Yamamoto Era' in MLB. We look forward to the legendary records he will write in the future and support Yoshinobu Yamamoto's bright future.
