Imai (1-0) picked up the win in Saturday's 11-0 rout of the A's, allowing three hits and three walks over 5.2 scoreless innings. He struck out nine.
After a bumpy MLB debut that saw him last just 2.2 frames, the 27-year-old righty looked much more comfortable in his second trip to the mound Saturday as he fired 58 of 94 pitches for strikes and came one out short of his first quality start for the Astros. Imai will take a 4.32 ERA, 1.56 WHIP and 13:7 K:BB through his first 8.1 innings into his next outing, which lines up to come on the road next weekend in Seattle.

Astros' Tatsuya Imai: Efficient in spring debut
Rotowire
Imai started Thursday's Grapefruit League matchup against the Mets, allowing one hit in a scoreless inning.
Imai would face the minimum in his spring debut, ultimately needing just 10 pitches to get out of the frame. After giving up an infield single to Marcus Semien, the right-hander coaxed a pop-up off the bat of Mike Tauchman before getting Bo Bichette to ground into a double play. The 27-year-old Imai is expected to play a big part in an Astros rotation that lost Framber Valdez in free agency. Imai signed a three-year deal with Houston after posting a stellar 1.92 ERA with 178 strikeouts across 163.2 innings in 2025 with the NPB's Seibu Lions.
