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.
Positional Profile: RHP/OF Pitch-ability right hander that is flashing stuff that creates swing and miss vs. LH and RH hitters. Solid feel for 3 pitches and pitching.
Body: 6-6, 209-pounds. Physical presence with broad shoulders and athletic trim.
Delivery: 1B side setup. Side step and small slide, turning into his pivot. Kick to the low chest. Controlled head and upper half, working level and in-line. Lands on-line with a square foot-strike. Active lower half allows the body to work on-line with some ease. Small finish to the 1B side.
Arm Action: RH. Long action, plunging out of the glove. Front side works slightly above shoulder level. Over-the-top with average to above arm speed.. Has intent with all pitches.
FB: T88, 85-88 mph. Solid run and ride. Showed feel for pounding the down zone. T2315, 2218 average rpm.
SL: 75-77 mph. Short, late action. Similar window to the fastball. More missed barrels than bats. Pitch should continue to mature in coming years. T1686, 1656 average rpm.
CH: 77-79 mph. Excellent arm speed. Good feel for landing to the arm side. Ball fades late. T2111, 1778 average rpm.
ATH: 28.00 max vertical.
