RHP/3B Tyson Grulkowski (Muskego, 2026) is a 6-foot-5 two-way player with upside on both sides of the ball. On the mound, despite his lanky levers, he is an ultra-clean mover, pairing it with a loose and quick arm. His fastball was up to 86.4 mph with carry and run, showing natural feel to go in and out with it. His hard slider had sharp 11/5 tilt with tight break through the zone, at 77-78 mph and also nearly 2,700 RPMs on average. He rounded out his repertoire with a deceptive changeup in the low-80s that featured big running action, roughly 18” on average, and depth. Offensively, Grulkowski put on a show during his BP round, as he led all in attendance with a 100.8 mph max exit velocity, while also averaging 95.1 mph. Grulkowski showed quick movements with the bat with strong hands and an uphill, pull-heavy approach. It’s a whippy barrel through the zone with a narrow set-up and quiet, early toe-tap. Defensively he showed a quick first step with athletic arm action. His 87 mph throw across the diamond was among Saturday’s leaders, too.
2/18/23

RHP/3B Tyson Grulkowski (Muskego, 2026) may have been one of the day’s biggest winners, regardless of class. Grulkowski stands a long, wiry, and projectable 6-foot-3, 190 pounds, and his athleticism produces a well-sequenced swing that produces easy bat speed that allows him to leverage balls to all fields efficiently. Additionally, Grulkowski is an impressive defender on the infield, where his athleticism blends in well and his footwork and arm strength (84 mph max) project to develop seamlessly into a third base profile. He was just as promising from the mound, too, where he reached an 83.2 mph high, which led all freshmen, and he spins it at a high rate that raises his ceiling even higher. The spin translates to the curve and slider, which both feature high spin rates and not just for his age, and the changeup is a promising point of development to watch as well. His performance in Waukesha allowed him to burst onto the scene as an instant follow member of the state’s 2026 class.
