2026 National Rankings Spotlight: Tyson Grulkowski
January 16, 2026
Wisconsin prospects have continued to gain national recognition in recent years. Following last month’s rankings update, 10 players from the Badger State earned spots inside the national top-500. Today, we highlight the highest-ranked right-handed pitcher of the group, Tyson Grulkowski (Muskego, 2026).
Committed to South Florida, Grulkowski joined Santarelli at the All-American Game this past September in Miami. The right-hander is ranked No. 2 in the state's 2026 class, No. 51 nationally, and the No. 13 ranked RHP in the nation. Grulkowski will be throwing a bullpen in a few weeks at the 2026 Super Sixty in Illinois.
Scouting Report
Showed some electric stuff this morning on the mound. Striking out three through one plus innings. FB: 86-89 mph, SL: 74-77. The South Florida commit and number two ranked pitcher in the state attacks hitters with a low ¾ arm slot.
Recent South Florida commit, one of the top right-handers in the state, currently ranked No. 9 in the state’s junior class. Listed at 6-foot-5, 227-pound long levered right-hander exhibited a consistent, repeatable, and low effort arm action out of a lower ¾ slot while throwing five shutout innings with nine strikeouts against Oconomowoc on May 22. Fastball sat 87-89 MPH, topping 91 MPH with life, while also mixing in a sinker. Showed advanced feel for a sharp two-plane slider at 75-78 MPH , consistently throwing it for a first pitch strike, as well as a swing-and-miss pitch later in counts.
+ RHP/1B Tyson Grulkowski (Muskego, 2026) is one of the top uncommitted arms in the region, and his performance Sunday was one of the best on a loaded roster. His physicality immediately stands out, as a 6-foot-5, 227-pound prospect who moves very fluidly on the mound, a clean, fast arm that delivers the ball from a 5.2-foot release height on average, extending down the mound at over 7 feet. His low ¾ arm slot really complements his entire arsenal, a fastball, sinker, sweeper, and change. The fastball, 87-89 mph, spins at roughly 2,300 rpm that had late life and run. The sinker, however, really stands out given his arm slot, at 87-88 mph with 17.3 inches of arm-side movement that he landed in the zone more often. The sweeping slider, 75-77 mph, led the event in average spin rate (2,768 rpm) with 14 inches of glove-side action (0.5-inch IVB avg.). His changeup, 80-82 mph, is deceptive with arm-side fade and run too. Grulkowski is also a middle-of-the-order type of hitter, with a max exit speed of 102.0 mph and over 78.1 mph bat speed on average. It’s easy to envision another climb in velocity in the near future, which would only enhance a special profile.
