6-foot, 175-pound frame, projectable with room to add strength. The right-hander utilizes a hybrid windup with a small leg-lift and coil into balance point, riding a tall/fall lower-half down the mound before moving into a clean ¾ slot. The fastball played 88-89 mph in this look with some carry through the zone and feel for strikes. He can spin the breaking ball at an above-average clip, spinning his curveball over 2,500 rpm on occasion with big sweeping action, 70-72 mph. The changeup showed similar shape to the fastball with over 20” of run, 80-82 mph and flashed strikes.
