The Astros and right-hander Tatsuya Imai are in agreement on a three-year, $54MM contract, according to Jon Heyman of the New York Post. Heyman adds that Imai can earn up to $3MM per year in incentives if he reaches 100 innings. The deal contains opt-outs after every year, per Jesse Rogers of ESPN.
Imai was one of the top starters available in free agency and coming off a career-best 1.92 ERA season with the Saitama Seibu Lions of Japan’s Nippon Professional Baseball. It was reported several days ago that he was meeting with teams in-person in advance of his January 2 signing deadline. The Yankees, Mets, Cubs, Phillies, and Orioles were among the clubs interested in signing him, so the Astros are a bit of a surprise destination.
We at MLBTR ranked Imai No. 7 on our Top 50 Free Agents list and projected him for a six-year, $150MM contract. This deal with Houston comes in at half the length of that projection, with around a third of the guaranteed money. Meanwhile, the annual opt-outs will allow Imai to test the market if he can prove himself in MLB.
Imai is 27 years old (28 in May) and coming off a run of dominance from 2022-25 in NPB. After posting a 2.41 in nine starts with the Lions in 2022, he followed up with a 2.30 ERA and a 24.4% strikeout rate in 133 innings in 2023. While he did walk 11.4% of hitters that year, Imai’s strikeout and walk numbers improved year over year from 2023-25. This year, he struck out 27.8% of hitters (best in NPB) and walked just 7.0%. His 20.7% K-BB rate was third-best in that league.
More to come.
