Born: 02/06/1995 (Age: 24)
Bats: Right Throws: Right
Height: 6' 4" Weight: 170
Mechanics
Extra-large frame with a lean, wiry body, high-waisted, and looks like he can add muscle mass in upper half, but is unlikely given age and body structure. Pitches from a semi-wind, long and loose arm with above-average arm speed to a high three-quarters slot. Elbow gets high in the back, loose arm overall.

Pitch Type Future Grade Sitting Velocity Peak Velocity Report
Fastball 60 93-96 96 Went down in third inning to more 93-94, but could reach back when needed. Firm with mild run, can lose ball up and out of the zone given looseness of arm action. Was probably around 85% FB in viewing, likes it. Out pitch, plus overall offering.
Slider 45 84-85 85 Inconsistent, used more second time through, tended to be sweepy with early action but showed average depth and action. Not a sharp offering but was effective when down in the zone, used only to RHH hitters. Future fringe offering.
Changeup 30 88-89 89 Lacks feel at this stage. More a BP fastball, used only to LHH as change of pace offering,
Overall

24-year-old right-handed reliever in High-A. See as a middle reliever/longman. Good plus fastball, but slider is a fringe offering, and command/control is below-average. Can fill a role on a ML staff though. Moderate interest, moderate risk.
