Grip Strgth (LH)
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.
Physical: Projectable 5-foot-11, 150lb build with a strong lower half. 9.46 runner in the 60.
Offensively: LHH. Upright, spread stance, as the hands worked calmly at the shoulder. Utilized a leg-kick stride to initiate the swing through a flat path with natural separation. Balanced finish repeated on the backside, allowing for a line-drive approach at the front of the plate when on time. Recorded a T77 mph exit velocity via Trackman during his round.
Defensively: The primary corner infielder featured developing footwork around the bag at first. Set up with a slightly narrow base, bending in the knees while presenting the glove-hand. Delivered an accurate 64 mph throw across the dirt.
Pitching: Starts off the middle of the rubber; above-average pace and hides it well on the move down the mound. Clean on the front side through H ¾, holding 66-68 mph for strikes (44% zone rate). Mixed a consistent, fading 62-63 mph CH at 1310 rpms.
