Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Grip Strgth (RH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Uncommitted. Currently ranked No. 14 in the state. 5-foot-11, 160-pound frame, lean and wiry with room to add strength throughout the frame. Started at short and hit out of the two-hole, finishing the day 1-for-3 with a sac fly. Clean right-handed swing with a loose operation, comfortable appearance in the box with confident takes, minimal swing/miss or chase in this look, swing you can dream on. Athletic defender with smooth actions and soft hands, fluid footwork through the baseball with some bounce in the feet, rangy actions. Quick release with a clean arm, accurate throws across. High-level shortstop to follow in the coming years.
5-foot-11, 158-pound, athletically-built, right-handed hitting infielder made a strong statement at his first-ever event. Offensively, he has a highly-repeatable, balanced swing that works on-plane, on time and all over the barrel to both gaps. Should only continue to add to his 86.3 mph exit velocity as he gains strength to the frame. Polished overall offensive skill set. Defensively, plays low to the ground, fundamentally sound and steady hands. Chance to stick on the infield. Advanced run through/body control play. Upside to all parts of his game.
Positional Profile: SS/RHP
Body: 5-11.4, 170-pounds. Trim frame with room for added strength.
Hit: RHH. Balanced setup, slight rhythm in the hands pre-pitch, short stride, utilizes lower-half. Balanced and clean swing, longer path with extension through impact, on the barrel up the middle of the field. 61.5 mph bat speed with 8g of rotational acceleration.
Power: 91 mph max exit velocity (86.3 avg.); 303-foot max batted distance.
Arm: RH. INF - 75 mph. Short arm action, 3/4 slot, works on the move and from different slots.
Defense: Two hand gather, shuffle to throw, clean feet with range.
Athletic Testing: 7.64 runner in the 60-yard dash; 19.80-inch max vertical jump.
Vizual Edge: 84.43 Edge Score.
