As we head into the fall, we are beginning to see tons of 2024 graduates make commitments to play at the next level. Indiana's 2024 class features a deep crop of talent, with plenty of prospects still left on the board. Today, we take a deeper look at '24 RHP Jack Grunkemeyer of Batesville HS.

 

Jack Grunkemeyer RHP / Batesville, IN / 2024

A physical right-hander - Grunkemeyer had a breakout junior season and is one of the top uncommitted arms left in the class. The 6-foot-2, 205 pounder provides a tough-look on right-handed hitters as he pitches from a low 3/4 arm slot that allows him to have unique properties on a fastball that is up to 90 mph. His fastball grades highly in two very different advanced fastball metrics, Hop+ and Sink+. His low release height + high spin metrics allow him to create a flat approach angle at the top of the zone, creating swing-and-miss and fly ball contact on top of the zone fastballs - but he is also able to create horizontal run on fastballs placed down in the zone, where he is able to get ground ball contact. These properties help Jack to get outs with his fastball, a trait that should carry over to the college level. Grunkemeyer tunnels a fading, 78-80 mph changeup off of his fastball and is able to create sweeping action on a 70-73 mph slider.
