Yoshinobu Yamamoto Overcomes Early Struggles, Becomes All-Star and Postseason Ace

Yoshinobu Yamamoto, who signed the largest free-agent pitching contract in MLB history with the Los Angeles Dodgers, faced initial communication challenges with his interpreter, Yoshihiro “Hiro” Sonoda, who lacked a baseball background. The Dodgers addressed this by putting Sonoda through an intensive "baseball boot camp" and leveraging Will Ireton's expertise to help both Sonoda and Yamamoto adapt. Ireton, the team's director of Japanese player operations, regularly assists during mound visits and pitch-data relay. Despite an underwhelming first half in his 2024 debut campaign, the Dodgers' infrastructure helped Yamamoto overcome these hurdles. He became an All-Star this season and is now performing as one of the best pitchers globally, recently throwing the first complete game in the MLB postseason since 2017.
