What happened: Jon Heyman first reported the decision, which Bob Nightengale echoed. The Astros named Imai a starter in July before moving him to the bullpen later that month.

Why it matters: Houston retains a pitcher who made 15 starts and eight relief appearances in 2026. His walks remain a concern as the club sets its pitching staff for next season.

What to watch: Spring training should clarify whether Houston gives him another chance in the rotation.
