Tatsuya Imai (Houston Astros) was drafted first overall by the Seibu Lions in 2018 out of Sakushin Gakuin High School in Tochigi Prefecture. He overcame early shoulder injuries and emerged as a dominant ace from 2022 onward — claiming the NPB strikeout title in 2024 and posting a career-best 1.92 ERA in 2025. Armed with a mid-90s fastball, a diving forkball, and a sharp slider, Imai signed a 3-year, $54 million deal with the two-time World Series champion Houston Astros in January 2026 via the posting system. At age 28 with seven years of NPB refinement behind him, he made the Opening Day rotation and is now competing alongside Framber Valdez and Luis Garcia Jr. in one of MLB's best starting rotations. His 2026 Astros stats, start-by-start results, and ERA trends are updated daily on this site.
