Originally selected late in the 2015 MLB Draft by the Milwaukee Brewers out of Oklahoma State University, right-handed pitching prospect Jon Perrin reached Double-A Biloxi in 2017, appearing in 23 games (12 starts) and finishing 5-3 with a 2.91 ERA over 105.1 innings pitched, with 91 strikeouts against 103 hits and 21 walks allowed. Across his entire professional career, Perrin has been something of a control artist, allowing just 1.5 BB/9 while producing 8.2 K/9 over 305 minor league innings spanning three seasons.
This fall, the Milwaukee Brewers sent Jon Perrin to the Arizona Fall League to pitch for the Salt River Rafters, and that’s where we saw him make several starts in October and November. The 24-year-old righty (DOB: May 23, 1993) threw 15.1 innings with Salt River, appearing in nine games (three starts), finishing 2-1 with a 4.70 ERA and 10 strikeouts against 19 hits and eight walks. Below, we’ve got a full Jon Perrin scouting report that includes game videos, tool grades, projection notes, and more on the 6’5″, 220 lb. right-handed pitcher.

Jon Perrin Scouting Report — Notes & Analysis
Jon Perrin isn’t anything particularly special, but he really grew on me the more I saw him pitch this fall for Salt River. He has a deep repertoire with some ability to manipulate pitches and sequence hitters with different wrinkles the first and second time through the order, even with the short leash he was on at AFL. The Milwaukee Brewers prospect is a consistent strike thrower with a proclivity for challenging hitters, and he’ll throw virtually anything in any count, the combination of which results in consistently weak contact when he’s keeping the ball down in the zone.
His two-seam sinker has a chance to be a special pitch aided by Perrin’s command profile, and the righty maintains enough of a distinction between his curve and slider at their best that he should be able to continue using both, and even play them off each other as consistency improves. Perrin will be 25 years old in May, so it’s really time to make a move towards The Show, but I think he’s in a particularly good position to do so and could become something of a nice sleeper surprise who could help the Milwaukee Brewers out fairly soon.
Jon Perrin Scouting Report — Future Projection
Jon Perrin is unspectacular but consistent, a strike-thrower with composure and an arsenal that has gotten by even when lacking in above-average stuff. Because of that, the future profile is likely in middle or long relief, with a swingman starting gig as a possibility here or there. For me, though, there’s still an outside shot Perrin out-pitches the projection and finds himself starting more than a few games as a back-end rotation arm. His ability to manipulate and change his sinking fastball with the trust to play his entire arsenal off the pitch gives the Milwaukee Brewers prospect tools to face hitters from both sides multiple times through a lineup.
Perrin is not a prospect, and he must succeed above Double-A before we go too far, so 2018 is the first step to that; I’d expect him to spend much of the year in Triple-A and maybe even get a first crack at the big leagues in Milwaukee depending on how he pitches. But even with the righty more of a fringy arm than a big league difference maker, don’t lose sight of Jon Perrin for too long; this kid knows how to pitch with an arsenal deep enough to execute what he wants to do, and the command profile that’ll aid him in the big leagues in whatever role he may hold.
Overall Future Potential (Future Value): Deep enough repertoire to earn a back-end rotation gig at ceiling; floor as up-and-down swingman or in middle/long relief (45)
MLB ETA: 2018
