5/1/2026, 11:13:15 PM
Imai’s First Rehab Start
Right-hander Tatsuya Imai made his first minor-league rehab start on Tuesday with Double-A Corpus Christi. In two innings he surrendered five earned runs on six hits (one homer), three walks and two strikeouts on 59 pitches. Manager Joe Espada said Imai will get another start soon, though the level is undecided.
Offseason Deal & Early Struggles
Imai arrived as the Astros’ marquee offseason acquisition, signing a three-year, $54 million deal after rejecting longer-term, lower-value offers. He debuted in late March, but in three starts posted a 7.27 ERA, 2.08 WHIP and a 13:11 K:BB ratio over 8 2/3 innings. He was placed on the 15-day injured list on April 13 for right-arm fatigue.
Performance Snapshot
Imai’s rehab start produced 5 ER, 6 hits (including a homer), 3 walks and 2 strikeouts on 59 pitches. His MLB numbers before the injury were a 7.27 ERA, 2.08 WHIP and a 13:11 K:BB ratio over 8 2/3 innings in three starts.
Team Statements
Astros manager Joe Espada confirmed the rehab schedule, noting the need for “additional work to rebuild arm strength and command.” General manager Dana Brown has not issued a formal comment, but reports indicate he is monitoring Imai’s progress and expects the pitcher to rejoin the rotation once cleared.
Critique & Role Debate
Analysts question Imai’s suitability as a starter, citing limited endurance, cultural adjustment issues and interpreter gaps. Some suggest a bullpen shift if control does not improve. The criticism is heightened by the gap between rumored $150 million offers and his actual $54 million contract.
Reporting Gaps
Sources differ on Imai’s activation timeline. CBS Sports says he could return “at some point in May,” while other outlets suggest the Astros may extend his rehab indefinitely. No official statement confirms a potential bullpen conversion.
Future Outlook
Imai is slated for at least one more rehab start before the Astros decide his roster status. Improved performance could see him back in the rotation in May; otherwise a bullpen role may be considered. Fantasy managers should watch his innings limits and K:BB ratio.
