5-foot-9 ,165-pound right-handed pitcher. The showing at the event was very good as he threw strikes, competed and showed plus stuff. The fastball sat 86-88 mph with arm side run to the pitch. The spin pitch was slurvy in shape, sitting 73-74 mph. The changeup is a developing pitch, sitting 79-80 mph. The delivery is quick in tempo and the action is repeated. The slot is above 3/4 and he pitches aggressively. The feet are online and shows good athleticism on the mound. He is a good prospect with an excellent repetiore.
