The Milwaukee Brewers will have a whopping eight representatives in this year’s Arizona Fall League, suiting up for the Salt River Rafters. We learned a couple of weeks ago the four position players that Milwaukee had selected - Monte Harrison, Corey Ray, Lucas Erceg, and Jake Gatewood - but their four pitching spots had yet to be determined. That is, until yesterday, when it was announced which arms will be heading to the showcase league this fall:

RHP Jon Perrin

Perrin, 24, was Milwaukee’s 27th-round pick back in the 2015 draft. His stock has ticked up quite a bit from late-round college senior draftee (who has previously said that he’d retire if he’s accepted into Harvard Law) to now an AFL representative. He spent all of 2017 with AA Biloxi, though he did miss a few weeks with an undisclosed injury. The 24 year old right-hander posted a 2.91 ERA/2.60 DRA with 91 strikeouts and 21 walks in 105.1 innings for the Shuckers this season. Here’s what former BP and current Brewers scout James Fischer had to say about Perrin:

Perrin is a large framed right handed starter with the potential for 3 average pitches. The fastball features slightly above average velocity paired with deception and the ability to command the pitch to 4 quadrants of the plate. The slider features short bite in the zone. He throws plenty of strikes and will be a durable innings eater at the highest level.

LHP Quintin Torres-Costa

Like Perrin, Torres-Costa was a late-round selection in the 2015 draft, getting popped in the 35th round. The native of Hawaii has turned himself into quite an intriguing relief prospect, getting all the way up the AA level this season. In 66.0 innings split between high-A Carolina and AA Biloxi, Torres-Costa fashioned a 4.23 ERA/3.37 FIP with 91 strikeouts and 32 walks. This is what 2080 Baseball had to say in their preseason report:

The medium-framed, athletic lefty sits in the lower 90s with his fastball and relies on a short cutter and circle changeup as his primary secondary options. The changeup has a chance to be plus and the deception he gets from his 3/4s arm slot and slight crossfire delivery have helped him to miss bats at a pretty good clip as a pro. With improved fastball command, he has a chance to be a quality lefty specialist down the road.

RHP Nate Griep

Another 2015 selection, the Brewers grabbed Griep in the 8th round out of Kansas State University. He’s served as a closer while pitching professionally, locking down the 9th inning for high-A Carolina this season. In 49.1 innings for the Mudcats, Griep compiled a 2.37 ERA and saved 30 games in 33 chances, but had a less promising 4.63 DRA while striking out 41 batters and walking 24. Baseball America offered this pre-draft report on the now soon-to-be 24 year old:

A redshirt sophomore, Griep showed improved maturity and velocity this season, as he will bump 93-94 mph pretty regularly and touched 96 at his best. Griep mixes in a hard R.A. Dickey-style knuckler as his changeup and a below-average curveball. Griep showed improved consistency as a sophomore and still has some room for refinement.

RHP Adrian Houser

Houser was one of the players that came back in the 2015 Gomez/Fiers trade with Houston and even briefly debuted in the big leagues with Milwaukee that September. He was pitching in AA Biloxi in 2016 when he injured his arm and was forced to undergo Tommy John surgery. Back on the mound this season, Houser made 9 rehab appearances between Milwaukee’s AZL affiliate and A-ball Wisconsin. The 24 year old looked perhaps sharper than expected, posting a 1.02 ERA/2.20 FIP in 17.2 innings with 27 strikeouts and just 4 walks. The AFL will provide an opportunity to get some more rehab innings under his belt to prepare for a full workload - and perhaps some time in the MLB - in 2018. Here’s what 2080 Baseball thought of Houser in their preseason report, before he was able to get back on the mound:

When healthy, Houser will show an above-average fastball with good life while mixing in an average curve and fringe-average changeup. He rounds out the arsenal with a solid cutter that serves to miss barrels, giving him a fastball look and a finish that runs opposite of his two-seamer. Without a true swing-and-miss secondary, Houser profiles as a back-end starter or swingman, though there’s a chance he emerges as a capable relief arm if his fastball/cutter combination prove effective at drawing ground ball contact at the big league level, as well.


The 6-team Arizona Fall League begins play this year on October 10th. The annual Fall Stars Game is scheduled for November 4th, and the league championship will take place on November 18th in Scottsdale.
