(14.4 mph hand speed average). Setup is comprised of a wide balanced stance and a controlled toe tap stride. Bat speed is quick developing, exhibits a simple upward swing plane and high finish. Found some barrels with some loud contact. Gap to gap approach. Projectable in the infield, displayed a velocity of 61 mph; showed smooth developing feet, a clean exchange, and soft hands. Laterally, movements were average and fielded the ball out front. Consistent accuracy to the bases, used a ¾ slot and a loose arm action.
