6-foot-3, 205-pound left-handed pitcher. The fastball sat 87-88 mph with arm side action to the pitch. The spin pitch was a slider, sitting 71-73 mph and solid action to it. The changeup is a developing pitch for him. The delivery is solid in tempo and he works down the mound. The arm works extremely well and the leverage for the mound is good. Good looking prospect.
6-foot-3, 195-pound left-handed pitcher. He turned in another solid performance at the event. The fastball sat 83-84 mph with arm side action to the pitch. The command of the fastball in the zone can improve as he matures in age. The slider is an out pitch, sitting 75-76 mph with late action. The changeup was solid, 68-71 mph with minimal fade and action to it. The delivery is solid in tempo as he gets down the mound with ease. The feet are online, firm front leg and the slot works quickly out of a high 3/4 angle. He is a good prospect on the mound
Scouting Report: 6-foot-2, 185-pounds, leaner, athletic frame, with room for added weight gains. A Left-handed pitcher, the delivery is advanced for his age, having tempo, rhythm, and using the entire body to pitch the baseball. The arm action is long and loose, working from a higher slot, pitching down hill. The fastball was clocked at 85 mph, with late action to it. Breaking ball is thrown with good hand speed, reached 74 mph, a swing and miss pitch. Showed a plus change up. Big time future.
