Acquired from the Mariners in the 2015 trade for Adam Lind, Peralta has long been knocked for being too undersized for a starting pitcher. He hardly let that get in his way in 2017 as he cruised through high Class A Carolina and Double-A Biloxi, posting a combined 2.63 ERA with 169 strikeouts in 120 innings. He led the minors with a .178 opponent average.
Peralta is confident and aggressive on the mound, challenging hitters with a fastball in the low to mid-90s, with good movement and improved command. He has deception with a bit of a crossfire delivery, and hitters have trouble picking up the ball, leading to plenty of swings and misses. Because of his “disappearing fastball,” many have compared him with former Brewers starter Mike Fiers, who got the job done without an overpowering fastball because hitters picked up the ball so late. Peralta repeats his delivery well and mixes in a slider to keep opponents off his fastball. He also has an above-average changeup he throws for strikes with deceptive arm speed. Peralta strikes out opponents with seeming ease but still issues too many walks and must improve his control. He displays good mound presence and a feel for pitching, particularly given his youth. He’s an intelligent pitcher with good instincts.
Despite concerns about Peralta’s size, the Brewers believe he can be a mid-rotation starter because of his stuff and intangibles. He might be challenged with an assignment at Triple-A Colorado Springs.
