Notes

Houston continues to rotate through outfield combinations as Joey Loperfido, Cam Smith, and Zach Cole all get another look, suggesting the club is still weighing depth and defensive alignment before Opening Day. Cavan Biggio’s start at designated hitter and Riley Unroe’s inclusion at third base point to continued evaluation of bench flexibility, while Nick Allen remains firmly in the shortstop conversation as Houston finalizes its infield picture.
