RHP Jackson Clark (Hinsdale Central, 2025) is an upside arm to note from the event. At 6-foot-6, 180-pounds, Clark moves well with a controlled tempo, while accelerating through release. His arm plays loose and he worked a three-pitch mix with his fastball topping out at 84.2 mph with slight cutting action to it. He showed a short-breaking curveball that had downer action at 72-73 mph and a fading changeup that had the ability to land for strikes.
RHP Jackson Clark (Hinsdale Central, 2025) is listed at a projectable 6-foot-6, 175-pounds with long levers and plenty of room to fill out. His delivery is athletic and loose, moving with a high leg-lift into balance point before moving down the mound with an in-line stride. His arm plays with a long arm swing out of the glove into a 3/4 slot, remaining fluid throughout. His fastball sat right at 78-80 mph (T2310 RPM) and averaged over 16' of run (T18.2'). His curveball played with gradual 11/5 shape and downer action, 65-67 mph. His changeup played with some downer break and was kept mostly down, 67-70 mph.
Positional Profile: RHP/1B
Body: 6-6, 175-pounds. Ultra projectable, wiry with room to add on strength and weight.
Delivery: Long lanky levers, big toe lifted leg lift, drop/drive, works in-line.
Arm Action: RH. Long arm action, 3/4 slot, loose creates some whip action.
FB: T80, 79-80 mph. Plays with run to arm side, occasional sink. T2310, 2237 average rpm.
CB: 65-67 mph. Higher slot at times, sweep action. T1881, 1820 average rpm.
CH: 68-70 mph. Tends to cut changeup, pulls to glove side. T1105, 975 average rpm.
