High waisted frame at 6-foot, 150 pounds and length throughout frame. Offensively starts slightly crouched with an open stance. Shifts weight back with a knee-knock load then gets into lengthy forward stride. Lands in wide hitting base with weight centered. Hands stay connected & keep barrel inside of the ball. Swing stays behind the ball and covers depth in the zone. Has some lift when he connects out front into a high, uphill finish. Defensively has strong carrying tools for the OF with his speed and arm strength. Shows both short, choppy footwork and longer strides when he needs to cover more ground. Comes thru the ball aggressively then uses a step behind shuffle to get momentum behind the throw. Long, full arm path with a high ¾ release. Loose arm action that produces true ball flight. On the mound, repeats his mechanics and maintains a consistent, steady tempo throughout. High leg lift at balance with a slight coil into his back hip. Hands come set just above shoulder height and upper half shows some inward rotation prior to hand break. Gets down the mound with intent and clean direction towards target. High glove side at separation but keeps shoulders level into landing. Same, long & continuous arm path that we saw in the OF. Braces up well with front leg and legs backside come thru after release.
