+ RHP Jonathan Kratz (Sun Prairie, 2027) is a long levered and projectable right-hander who put himself on the map with his performance on the mound on Sunday. Kratz pitched exclusively out of the strength and delivered his arsenal from a high 3/4 arm slot. He levered the ball down hill and was up to 81 mph with his fastball. He deployed a sharp 12/6 curveball that displayed some out pitch characteristics. He rounded out his arsenal with a slider that provided more lateral break than the curve which should play well against same-handed hitters in game.
