Crosby is a dynamic mover on the mound with a quick arm, running his fastball up to 86.4 mph while sitting in the mid-80s throughout his ‘pen. His fastball plays with above average spin at 2,276 RPM and carry at 17.6” of IVB and was able to locate it in the zone. Crosby would also show the ability to land his low-70s curveball in the zone with short and quick breaking action. To round off his arsenal, he threw a changeup with intent with similar shape to the fastball. Crosby established himself as a follow prospect in the Badger State after his performance at the event.
