Tatsuya Imai Set to Rejoin Astros Rotation

Core Event
The Astros entered May with five starters unavailable: ace Hunter Brown, veteran Cristian Javier, right-hander Ronel Blanco, closer Josh Hader and Lance McCullers Jr. To fill the gap they turned to Japanese right-hander Tatsuya Imai, a three-year, $54 million deal. Imai has struggled with the major-league ball, mound, pitch clock and meal schedule. He was placed on the 15-day IL on April 12 after a start on April 10 where he could not finish the first inning. Manager Joe Espada said Imai will rejoin the rotation next week, likely against Seattle.
Data
Three starts gave Imai a 7.27 ERA, 2.08 WHIP, 11 walks and 13 strikeouts in 8 2/3 innings. A Triple-A rehab outing yielded five walks in three innings with 27 strikes out of 63 pitches; a later start allowed one run on one hit, three walks and five strikeouts in three innings. Injuries have left the team without four starters, increasing the need for a fourth arm.
Official Statements
Espada called Imai “a really good pitcher” who “belongs in the rotation – the Astros’ rotation” and is “ready to pitch in the big leagues.” GM Dana Brown said he is “a quality starter” but noted a “bump in the road with some of the walks.” Coaches urged him to “just be yourself and have confidence in your stuff because your stuff plays at this level.” Analysts said “his control must improve” before he is a viable waiver-wire option.
Impact
With five rotation spots vacant, Imai’s return could stabilize the staff and keep Houston competitive in the AL West. Limiting walks and maintaining pitch counts will be crucial as it navigates a crowded injury list while chasing a postseason berth.
