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: 5-10, 165 pounds; Proportional, slight build. 7.41 runner in the 60.
Offensively: RHH. Even setup, with feet just outside his shoulders; bat positioned at a 45 degree angle. Short take back with the hands with an up and down stride for timing. Slides weight forward pre-contact. while showing an aggressive lower half. Showed a compact swing path with a late one hand finish. More flyballs than line drives and groundballs with a peak exit velocity of 89 MPH via Trackman.
Defensively: Starts with a low to the ground setup; uses prep step while playing low to the ground. Hands are underneath the body with a clean transfer. Moderate arm circle from a high 3/4 arm slot. INF - 81 MPH.
