6-foot-1, 190-pound right-handed pitcher and right-handed hitting outfielder. The approach in the outfield was athletic and online, throwing 83 mph during the outfield portion of the workout. The bat had an exit velocity of 95 mph. The setup was athletic and he leaned on the baseball. He showed above average hand speed and feel for hitting. On the mound, the fastball sat 83-84 mph with minimal arm side run. The spin pitch was 72-73 mph and solid in shape. The changeup is a developing pitch for him.
