+ Grupenhoff is a big upside play, and I wouldn't be surprised to hear/see this really start to tick during the back-half of 2025. It is an ultra-projectable, 6-foot-5, 175 pound frame with long levers prevalent. The lower half of the delivery moves surprisingly well for his size with a loose arm working on top to an OTT slot with some whip at release. Strength should elevate a fastball that sat 82-84 at this event. The fastball played with big extension from a high release height and occasional carry, while his 69-70 curveball played off of it with glove-side depth. He showed a mid-70s change, as well.
