Clark

RHP Jackson Clark (Hinsdale Central) stands in a hard-to-miss frame with more still to come at 6-foot-6, 196-pounds. He’s a simple, easy mover with a long arm path out of a ¾ slot, and he showed a fastball that sat 81-84 mph with slight arm-side run. He threw both a curveball and a slider; his curveball playing with more vertical, 11/5 shape, and his slider showing more tight, short spin, thrown harder at 74-76 mph.

Uncommitted. 6-foot-6, 195-pound frame, lean and high-waisted, plenty of room to add on strength. Loose and easy mover, moves well down the mound, flexible lower-half. Loose arm path with a ¾ release, creates a fastball up to 87 mph, cruised around 83-85 mph with heavy arm-side run. Went to a short 11/4 curveball at 71-75 mph, developing shape. High-ceiling right-hander to keep tabs on.
