RHP Josh Marzec (Lake Zurich) is a must-know uncommitted arm in the incoming senior class. Standing in a projectable 6-foot-2, 195-pound frame with athleticism, Marzec showed a clean and easy operation with a long, loose and clean arm out of a high ¾ slot. His fastball sat 85-87 mph, topping out at 88 mph with mostly straight actions. He mixed in a low-70s breaking ball with 11/5 shape (-15.3” avg. HM) and showed feel to spin it for strikes, and he rounded out his three-pitch mix with a 79-82 mph change-up that produced fade at times (avg. 14.9” HM). He finished his two-inning outing with one strikeout and one walk. A arm-to-know in Illinois’ 2025 class.

Delivery: Simple delivery; repeats well, side steps into a controlled and high leg-lift, works with some pace, tall/fall, works in-line.
Arm Action: RH. 3/4 slot, medium/longer draw in the back. Didn’t allow a hit or run while striking out one in two innings of work.
FB: T88, 85-87 mph. Straight fastball; heavy; played well up in the zone; got up on hitters. T2174, 2063 average rpm.

RHP Josh Marzec (Lake Zurich, 2025) is an uncommitted name to know from the event.

He flashed some feel for a sweeping curveball at 68-69 mph and a shorter 10/4 slider at 71-74 mph to complement his fastball. He also showed above-average feel for a running changeup at 77-79 mph.
