True Sophomore. Formerly ranked No. 259 in Illinois’ 2021 class. One of the top arms out of the ‘pen for the Hawks last year, recording a 2.33 ERA in 19.1 innings, striking out 24 to only seven walks. The sidearm right-hander seems to have added a couple ticks to his fastball; reaching up to 81 mph, sitting 79-80 mph with heavy sink and advanced control of the zone. He also showed above-average control over his slider, playing with sharp 10/4 action and averaging over 2,600 RPM. Changeup plays with heavy sink and similar action to his fastball, 73-74 mph.
Heartland Scout Day: With a lean, athletic build at 5-foot-10, 155 pounds, the submarine right-hander peaked at 79 mph with his fastball, and impressed with a plus hard sinking changeup that he repeated down in the zone at 71-73 mph. His fastball had an event’s best of 22.7” of HM max and 21.5” avg HM.

5-foot-8, 145-pound right-handed pitcher, athleticism in actions. Stretch only, side arm/submarine delivery, squats at set, control and feel throughout, knee knocks to a short stride in-line, toe closed, smooth rhythm. Arm is loose and clean, sub slot, regular effort. Flashed three pitch feel with action on all, tough bullpen guy. Fastball, run and sink in the zone, 70-71 mph, topped 72 mph. Slider, 10/4 sweeper, 62-64 mph. Changeup, sinks and fades nice of his fastball, 64-68 mph.
