8/11/18 - Max FB: 77, FB: 74-76, CB: 60-61, CH: 69-70
5-foot-11, 175-pound, RHP showed intriguing arm strength for an incoming high school freshman. Medium, athletic frame w/ well-proportioned lean strength, super projectable. Pitches from a full wind-up into H ¾ release from the first base side of the rubber. Some effort in the throw w/ upright finish. Lands open, creating a longer look at the ball for hitters. Some downhill plane, angle. Straight FB showed occasional short arm-side run. Loose medium downer CB w/ developing rotation. CH w/ arm-speed, fade and sink. Around the zone.
8/11/18 - 60 Time: 7.59, Position Velocity: OF-84, Exit Velocity: 84
5-foot-11, 175-pound, RHH showed intriguing two-way potential for an incoming HS freshman. Medium, athletic frame w/ well-proportioned lean strength, super projectable. Offensively, hits w/ a slightly open, very slightly crouched stance w/ short hand rhythm into short knee to knee leg kick w/ deep hand load. Near arm bar, tendency to get too deep with hands and get caught coming through the zone. Pull oriented approach w/ lot of line drives. Present singles hitter w/ projectable gap power. Defensively, moves well in the OF w/ some length in the release and carry through target arm strength.
