Scouting Report

Video scouting report »

Scouting grades: Fastball: 55 | Slider: 55 | Changeup: 50 | Control: 45 | Overall: 40

Wisconsin's best prospect this year, Kussow flies under the radar more than he should. Like a lot of prep pitchers from cold-weather states, he lacks consistency, but he also looks like he belongs in the third round on his best days. He has the makings of a promising three-pitch repertoire and a projectable 6-foot-5 frame.

Kussow works with a low-90s fastball that tops out at 97 mph with some carry and armside run. He can overpower hitters with a high-spin slider that climbs as high as 88 mph with two-plane break. He hasn't needed to use it much, but his mid-80s changeup has encouraging fade and depth.

Kussow's size and ability to get down the mound well create a low release point and extension that make it difficult for hitters to pick up his pitches. He doesn't have the smoothest delivery, which further adds to his deception, though it also can compromise his ability to throw strikes. If he doesn't turn pro this summer, he could become one of the best college pitchers in the 2028 class after three years at Louisville.

Wisconsin's best prospect this year, it seemed like Kussow flew under the radar more than he should have. Like a lot of prep pitchers from cold-weather states, he lacked consistency, but he also looked like he belonged as a Day 1 pick in his best outings, thanks to a promising three-pitch repertoire and a projectable 6-foot-5 frame. The Mets took him in the fourth round and went above slot to sign him for $897,500.
