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.
INF Ethan Karaszewski (Wauwatosa East, 2026) is an interesting middle infield prospect who flashed tools and skill on both defense and with the bat. Karaszewski stands 5-foot-10, 152 pounds with fill and strength coming to his already athletic build. He displayed what scouts call “Hitter’s Hands” during batting practice with a loose, rhythmic and whippy swing that creates bat speed and consistent line drive contact out front. On defense, Karaszewski showcased fluid actions and soft hands in the middle infield. He certainly placed himself on the radar and is a name our staff will follow closely in the spring and summer circuits.
Positional Profile: SS/2B
Body: 5-10, 147-pounds. Athletic frame with fill and projection coming.
Hit: RHH. Wider base slightly open. Rhythmic, athletic, loose free and easy hands to and through the ball, drives ball to all fields, hitters hands.
Power: 84 max exit velocity, averaged 72 mph. 261’ max distance.
Arm: RH. INF - 76 mph. Compact arm, 3/4 slot.
Defense: OF: One-hand gather, works in-line, moves well side-to-side. INF: Two-hand gather out front, shuffle step on throws, fluid actions, soft hands.
Run: 7.57 runner in the 60.
