In a tough return to the majors after 32 days, Astros pitcher Tatsuya Imai was pulled after just four innings, allowing six earned runs—his worst performance since moving to the United States. 
Imai struggled with command, hitting two batters and issuing a walk before surrendering a grand slam. He also gave up a second home run, as all the runners he put on base via walks and hit-by-pitches came around to score on long balls. 
The right-hander, recalled from Triple-A, failed to find his rhythm, raising concerns about his mechanics and whether opponents have adjusted to his pitching style. The outing marks a significant setback for Imai, who had been aiming to solidify his spot in the rotation.
