2/04/23

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.
