RHP Gavin Rosengren (Batavia, 2025) was dominant over his 1.2 innings of work, allowing just one hit and no runs to pair with two walks and four strikeouts. Controlled tempo on the mound into a medium leg-lift, tall/fall down the mound and works mostly in-line. His arm works long out of the glove, working into a ¾ release. His fastball sat in the 83-86 mph range, topping out at 87 mph with life through the zone. Showed feel for both a curveball and slider in the mid-70s, both displaying late bite and depth at times.
