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 LHH/OF Projects well physically. Moves well, run times will increase. Solid OF'r, will have ability to play all 3 OF spots. Solid bat/power combo in future. Watch develop, will add needed strength, tools present. RHP athletic on mound. Repeats delivery. Low slot. Shows ability to spin baseball. FB effective life, can elevate for success. Developing secondary. Stuff will play with added velo.
Body: 5-10, 150-pounds. Wide shoulders, good back. Projects well physically.
Delivery: Side step rocker, high knee lift with inward turn. Loads into back leg. Cast stride leg out and down slope, lands online. Solid finish.
Arm Action: RH. Full circle with length to backside. L 3/4, side arm slot. Solid finish.
FB: T79, 77-79 mph. FB shows tail action to arm side. From low slot, can elevate for success. Solid FB spin present. T2215, 2143 average rpm.
SL: 70-71 mph. Can spin baseball. Frisbee, sweep/slurvy type. Flashes solid action. T2585, 2553 average rpm.
CH: 74-76 mph. Feel for change present. Tail/sink action. T1721, 1688 average rpm.
ATH: 7.12 runner in the 60. 1.67 and 3.91 in the 10 and 30 yard splits. Solid start and run form. Will develop into 6.9 or better runner in future. 19.50 max vertical.

Developing secondary. Stuff will play with added velo.
Body: 5-10, 150-pounds. Wide shoulders, good back. Projects well physically.
Hit: LHH. Toe tap stride. Rotational back foot, gets stuck and slides away from plate hindering use of lower 1/2. Drive back foot forward slightly with rotation, engaging lower 1/2 in swing. Increasing lower 1/2 results in more impact. Hits into firm front leg, posture is laid back at contact, would like see more upright at contact. Stride foot rolls onto side of foot, nice job hitting from ground up. Develop core strength with rotational core exercises to improve rotational acceleration. Barrel/hands in good launch position. Takes solid path to hit zone. Slight uphill path created with body laying back. Upright posture will allow ability to get on plane creating more line drive contact. (A lot of ground balls hit now are because you are coming over the top of balls) Bat/hand speed will increase with strength. 67.6 mph bat speed with 13 G's of rotational acceleration.
Power: 96 max exit velocity, averaged 86.0 mph. 331' max distance. Solid bat/power combo, hit over power. Adjustments will create increased contact consistency and impact.
Arm: RH. OF-86 mph. Arm works well, arm speed will develop. Accurate throws. Recommend long toss program to increase raw arm speed and raw arm strength.
Defense: Moves well to baseball, breaks down to field. Fields off left foot. Solid glove to hand exchange.
ATH: 7.12 runner in the 60. 1.67 and 3.91 in the 10 and 30 yard splits. Solid start and run form. Will develop into 6.9 or better runner in future. 19.50 max vertical.
