6/11/16 - Drafted in the 37th round by the Arizona Diamondbacks out of Heartland CC.

1/13/13 - At a physical 6-foot-6, 235 pounds, Malczewski cuts an imposing presence on the mound. The left-hander has made tremendous strides since we saw him as a junior. He cleaned up his mechanics and have subsequently enjoyed a significant velocity spike. His fastball sat 84-86 mph, working from a high-3/4 arm slot. His arm works with little effort, and he demonstrated good rhythm throughout his delivery. For his size, he maintains balance and showed solid lower half athleticism. Malczewski also showed feel for a 71-73 mph curveball that had some sweeping action. His 70-73 mph changeup also looks to be a good pitch, as it demonstrated arm-side sink down in the zone. Malczewski could be that prospect who, when you look back in three years, is a low-90s guy.
At 6-foot-5, 220-pounds, Malczewski possesses a lot of upside. The big left-hander operates from a 3/4 arm slot with a fastball that sat at 77-78 mph. Malczewski, who throws across his body, also showed a 66-68 mph sweeping curveball and threw a developing 68-69 mph changeup. With his size and some mechanical adjustments, Malczewski should see his velocity climb in the coming years.
