  Scouting Report & Links      
         
  Scouting Report: Physically imposing right-hander with a durable and sturdy frame built to handle a starter's workload. Repeatable delivery that allows him to constantly pound the zone. Repertoire relies primarily on a low-90s fastball sitting 90-93 mph and a sharp, 79-80 mph slider, occasionally mixing in a changeup and curveball. May be able to add velocity early in his pro development. Exceptional control and command. Notably yielded just 19 walks while striking out 86 across 96.2 innings in 2026. Transferred from Rock Valley College to UIC, slotting right in as the team's Friday night starter in 2026, tying for the MVC lead with eight wins and throwing multiple complete games.
