Astros and Japanese Ace Tatsuya Imai Agree to Three-Year, $54M Contract
HOUSTON — The Houston Astros have reached an agreement with Japanese right-hander Tatsuya Imai on a three-year contract worth $54 million, a source familiar with the talks said, marking one of the biggest international free-agent signings of the MLB offseason.
The deal includes annual salaries escalating from $16 million in 2026 to $18 million in 2027 and 2028, plus a $2 million signing bonus and performance incentives up to $3 million he can earn by passing innings-pitched goals this season. Imai also has opt-out clauses after the 2026 and 2027 campaigns, giving him flexibility if he posts strong Major League numbers.
If he reaches all the performance targets next year, the contract’s total value could climb to approximately $63 million over three seasons — a lucrative figure for a pitcher making his MLB debut.
At 27 years old, Imai enjoyed a standout career in Japan’s Nippon Professional Baseball (NPB) with the Saitama Seibu Lions, finishing his final season with an impressive 1.92 ERA and 178 strikeouts in 163⅔ innings. He also boasts a career that includes multiple All-Star selections and eye-catching strikeout performances.
This signing gives the Astros a major boost to their rotation as they aim to bounce back following a surprising offseason shake-up. Imai’s addition could position Houston as a stronger contender in the competitive American League West and deepen a pitching staff that aims for postseason success.
Imai becomes one of the highest-paid Japanese pitchers to join MLB, following elite arms like Yoshinobu Yamamoto and Masahiro Tanaka, and will bring international spotlight and excitement to the Astros’ 2026 campaign.
