(64.3 mph bat speed average). (18.9 mph hand speed average). Began in a narrow open stance with a controlled load, then used a closed small stride. Has a level swing plane, developing bat speed and level finish. In his round he found some barrels with some loud contact. Line drive approach. Capable from the outfield, he made throws to the infield at velocities up to 76 mph; had developing soft hands, developing footwork, and a developing exchange. Fields the ball out front, movements laterally were developing. Had a high ¾ slot and consistent accuracy to the bag. Capable on the mound, used a consistent arm action and a ¾ arm angle while showing developing arm speed. Feel type pitcher who uses some effort. Showed consistent balance point and in line shoulders. Lands closed with a falling off finish. Sat with his fastball at 73-74 mph; shows running sinking action and command around the zone. (Max spin 2090; Avg 1960). Shows sweeping action and glove side around the zone control on his curveball (66-67). (Max spin 2046; Avg 1933). Showed glove side control and slurvey action on his slider (68-69).
