Trey Supak dominated AA hitters over his 20 starts with the Biloxi Shuckers in 2019. During his time in Mississippi he posted a 2.20 ERA in 122.2 innings. Hitters that faced him at that level batted just .192 against him. At that point in time, he look like he would be the run-away favorite for every pitcher of the year honor that could be bestowed on a Brewers’ prospect. In fact he pitched so well over 20 starts with Biloxi that he was named the Southern League Pitcher of the Year.
His dominance earned him a promotion to the AAA team in San Antonio. Things did not go as well there. He certainly did not have the time to make adjustments to level of hitter he was facing. For the Missions, he pitched in just 30 innings over seven starts, which were unfortunately marred by a 9.30 ERA. His performance in San Antonio likely cost the 6’5”, 240 lb. pitcher the Robin Yount Award for Pitching, which goes to the best minor league pitcher in Milwaukee’s farm system in a particular season.
Supak will turn 24 years old this upcoming May. The key question going into next season is can he make the necessary adjustments to get AAA hitters out. His approach is pitch-to-contact, so he must rely on pinpoint command, deception, pitching mix, and movement. He does throw a low-to-mid 90s fastball along with a curve, slider, and change. That combination might get him to the Brewers at some point in the next couple of years as an effective starter or bullpen piece. If it does, it goes as another notch in David Stearns’ belt as added success in the Jason Rogers for Keon Broxton and Supak swap.
