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.
Right-handed hitting infielder, Gavin Grummer (Jacobs, 2025), had a hitterish, intentful look in the box and was on the barrel to the pull-side throughout his round. Grummer has athletic, strong hands, stays short to the ball, and swings with controlled aggression. Grummer showed well defensively as well, working with a two-hand gather to secure the ball out front and reaching up to 79 mph across the diamond.
Positional Profile: 2B/3B
Body: 5-9, 165-pounds. High waisted frame with a strong lower half.
Hit: RHH. Narrow, open setup, long stride. Athletic, strong hands, stays short to the ball, controlled aggression and was on the barrel to the pull-side.
Power: 90 max exit velocity, averaged 83.5 mph. 304’ max distance.
Arm: RH. INF - 79 mph. Long, 3/4 slot.
Defense: Two-hand gather out front, moves well laterally, steady hands.
Run: 7.34 runner in the 60.Â
Positional Profile: 3B/OF
Body: 5-8, 145-pounds. Well-proportioned frame.
Hit: RHH. Narrow base, tall start, hands start back, smooth load with a leg lift trigger. Quick rotation out of load, aggressive intent, short and level path to contact, hard off the barrel to the opposite gap.
Power: 86.3 max exit velocity, averaged 77.2 mph. 299’ max distance.
Arm: RH. INF - 75 mph. OF - 77 mph. High 3/4 to 3/4 slot, lengthier path.
Defense: Quick reads. Clean exchange. Long to release at times. Plays through the baseball.
Run: 7.49 runner in the 60.Â
