7. RHP Trey Supak
Now we’ve reached the next group of pitching prospects in this farm system. Trey Supak was acquired by the Brewers, seemingly forever ago, back in December 2015. He was acquired with Keon Broxton from the Pirates in exchange for Jason Rogers. While Broxton made an immediate impact at the big league level, was traded, and since signed back with the team, Supak has methodically worked his way through the farm system.
Supak was brought onto the 40 man roster after the 2018 season, and burned one of his option years last year. He dominated in Double-A, pitching to a stellar 2.20 ERA in 20 starts for Biloxi, which earned him a mid-season promotion to Triple-A.
In Triple-A, things went haywire for Supak. In seven starts, Supak had a 9.30 ERA over 30 innings, giving up as many home runs in those innings as he did in 122.2 IP in Biloxi. Part of that could have been the juiced baseball that cause most Triple-A pitchers to struggle all year, but it’s still a troubling development. A 9.30 ERA is ridiculous.
Supak has a solid 4-pitch mix and he doesn’t walk many. His fastball sits in the low-90s and can hit 95 MPH, but is not a power pitcher. He succeeds with mixing his pitches and pitching to weak contact, instead of strikeouts.
When he gets to the big leagues, Supak could be a solid No. 4 starting pitcher. He’s big at 6’5″ and 240 pounds, and has a good mix of pitches to work with.
While he won’t earn a rotation spot out of spring training, unless a lot of things go wrong, Supak is likely ticketed for a return trip to Triple-A San Antonio, this time hoping for a better experience than last year.
He’s further down on the starting pitcher depth chart, but if the Brewers need to dip into the minors for a spot starter on short notice, Supak could be the guy. In the meantime, he comes in at No. 7 on our list.
