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.
RHP Jackson Clark (Hinsdale Central, 2025) stands out immediately thanks to his 6-foot-6, 195-pound frame, and he’s an uncommitted arm to monitor closely this spring. The big right-hander has a methodical delivery with a high leg-lift, working athletically downhill into a longer, yet clean arm action from a low ¾ release. His fastball played in the 83-85 mph range with some life through the zone and over 2,300 rpm at times with heavy run to the arm-side. He showed developing feel for his sweeping curveball at 70-72 mph, and also went to a changeup at 71-73 mph that he occasionally got around and cut from a lower slot.
Positional Profile: RHP
Body: 6-6, 195-pounds. High-waisted, long levers.
Delivery: Methodical delivery, high leg-lift, athletic downhill.
Arm Action: RH. Longer arm action, loose and clean, lower 3/4 arm slot.
FB: T85, 83-85 mph. Mostly straight, life through the zone. T2332, 2271 average rpm.
CB: 70-72 mph. Developing feel, flashed sweeping action. T2009, 1938 average rpm.
CH: 71-73 mph. From a lower slot, fade at times, tendency to cut. T1770, 1572 average rpm.
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.
