In 2024, Yoshinobu Yamamoto, the best pitcher who dominated Japanese professional baseball, entered the big leagues by signing a record-breaking 12-year, $325 million contract with the Los Angeles Dodgers. He was expected to be a key player in completing the Dodgers' 'super team' alongside Shohei Ohtani, but his first season wasn't smooth. However, after a tough adaptation period in 2024, Yamamoto has established himself as the Dodgers' ace as of the 2025 season, leading the team's World Series championship challenge. Let's take a closer look at his adaptation process with the Dodgers and his dazzling performance in the 2025 season.
Yoshinobu Yamamoto's 2024 season can be summarized by the word 'adaptation'. He drew many concerns by making a shocking debut, allowing 5 runs in 1 inning in the MLB opening game against the San Diego Padres in Seoul. Everything was a new challenge for him, including the MLB-approved ball, the 5-man rotation system, and frequent travel, which were different from Japanese professional baseball (NPB). In particular, his splitter, which was his main weapon in NPB, sometimes failed to drop or hung in the zone in MLB, leading to his being targeted. To make matters worse, he had to leave the field for about 3 months due to a triceps injury in June. Before the injury, he recorded a decent performance of 6 wins, 2 losses, and an ERA of 2.92 in 14 games, but there were also evaluations that he did not meet expectations. However, he showed a powerful pitching performance again after returning in September, and ultimately recorded 7 wins, 2 losses, and an ERA of 3.00 in the regular season. And in the 2024 World Series, he demonstrated his prowess as a 'pitcher strong in the fall', contributing to the Dodgers' championship and winning a valuable World Series ring.
The experience of the 2024 season became an important asset for Yamamoto. He actively changed his pitching style to match the characteristics of MLB batters and the league environment. In particular, he focused on improving the weaknesses of his splitter, which was his winning pitch in NPB, and further enhancing the power of his four-seam fastball and cutter. He also improved his efficient pitching operation and adjustment skills to match the long season and tight schedule of the major leagues. These efforts led to his overwhelming performance in the 2025 season. His stable control and the effective combination of various pitches were enough to overwhelm opposing batters. He has become not just a power pitcher, but a 'true ace' who intelligently manages the game.
The 2025 season proved that Yoshinobu Yamamoto is the Dodgers' ace. He announced a successful start with a 5-inning, 1-run performance in the opening game of the Tokyo series at the beginning of the season, and he consistently showed good form, lowering his ERA to the 0s. His final stats for the regular season were 12 wins, 8 losses, an ERA of 2.49, and 201 strikeouts in 173 2/3 innings, placing him second in the National League ERA, and his performance was overwhelming. In particular, in a situation where many of the Dodgers' starting pitchers were injured, Yamamoto was the only one to complete the required innings, firmly supporting the team's mound. His consistency and crisis management skills played a decisive role in the Dodgers' winning the division even in difficult circumstances.
Yamamoto's true value shone even more in the postseason. He led the team to victory by pitching a complete game with 3 hits, 1 run, and 7 strikeouts in the second game against the Milwaukee Brewers in the National League Championship Series (NLCS). This is a historic record as the first MLB postseason complete game by a Japanese player. Riding on this momentum, he also recorded a complete game with 4 hits, 1 run, and 8 strikeouts in the second game against the Toronto Blue Jays in the 2025 World Series, tying the series at 1-1. With this, he wrote another great record as the first Asian pitcher to have a World Series complete game and two consecutive postseason complete games. His 'big game pitcher' appearance, which saved the team at critical moments, left a deep impression on Dodgers fans.
The Dodgers are considered strong contenders for the championship in 2025, following their World Series victory in 2024. Along with the powerful batting lineup of Shohei Ohtani, Mookie Betts, and Freddie Freeman, the starting pitching staff led by Yoshinobu Yamamoto is playing a key role in their championship challenge. In particular, Yamamoto's overwhelming pitching power and stability, which he showed in the postseason, are one of the biggest driving forces for the Dodgers to advance towards the World Series championship. It is no exaggeration to say that the Dodgers' goal of winning the World Series two years in a row rests on his shoulders. The eyes of baseball fans around the world are focused on what kind of performance Yamamoto will show in the remaining World Series games.
