Right-hander Tatsuya Imai and the Houston Astros have agreed to a $54 million, three-year contract, a person familiar with the negotiations told The Associated Press on Thursday.
The person spoke to the AP on condition of anonymity because the agreement had not been announced.
Imai gets a $2 million signing bonus and salaries of $16 million this year and $18 million in each of the final two seasons. He can earn an additional $3 million in performance bonuses this year: $1 million each for 80, 90 and 100 innings.
His 2027 and 2028 salaries would escalate by the amount of performance bonuses earned in 2026, which could raise the deal's value to $63 million over three years.
Imai can opt out after the 2026 and 2027 seasons.
Under the posting agreement between Major League Baseball and Nippon Professional Baseball, a deal must be finalized by 5 p.m. EST Friday.
Imai receives the third-highest average annual value for a Japanese pitcher entering Major League Baseball behind Yoshinobu Yamamoto's $27.08 million with the Los Angeles Dodgers in a deal that started in 2024 and Masahiro Tanaka's $22.14 million with the New York Yankees in a contract that ran from 2014-20.
A 27-year-old righty, Imai went 10-5 with a 1.92 ERA last year with the Pacific League’s Seibu Lions. He struck out 178 batters in 163 2/3 innings.
Imai is 58-45 with a 3.15 ERA in eight seasons with Seibu, with 907 strikeouts in 963 2/3 innings. He is a three-time All-Star.
Imai pitched eight innings of a combined no-hitter against Fukuoka on April 18. He struck out 17 against Yokohama on June 17, breaking Daisuke Matsuzaka’s previous team record of 16 from 2004.
Under MLB’s posting agreement with NPB, Seibu will get a posting fee of $9,975,000 from the Astros and a supplemental fee of 15% of any earned bonuses, salary escalators and exercised options.
Imai joins a rotation projected to include Hunter Brown, Cristian Javier and Lance McCullers Jr.
