Honorable Mentions
DL Hall
10 G, 12 IP, 2.25 ERA, 4.31 FIP, 25.5 K%, 15.7 BB% 
Hall’s season is off to a great start. With his injury issues hopefully long behind him, he’s finally looking like the prospect that was advertised when he was in the Orioles system, posting a 1.59 ERA over 17 innings pitched thus far.

Not much has changed. The Brewers still depend on him to make multi-inning relief appearances, and his arsenal has far more variety than your typical reliever. He has begun to phase out his four-seam fastball and slider in favor of a new sweeper and heavier reliance on his sinker.

He has been successful, but there are a few points of concern. His walk rate is much higher than it should be, and his changeup has been giving up a considerable amount of hard contact, especially compared to last year. 

Statistical Nugget: Hall has thrown 42 sweepers so far this year, limiting opposing hitters to a .000 slugging percentage with a 60% whiff rate.

Aaron Ashby
12 G, 13 ⅔ IP, 2.63 ERA, 2.04 FIP, 33.3 K%, 14.3 BB% 
As the bullpen’s iron man, Ashby has been Milwaukee’s busiest reliever by far. Not only does he have 17 appearances this year, but eight of those outings were for more than one inning. The former starter has been excellent since returning to full health and has been an invaluable part of the pitching staff.

His walk rate is the only real blemish on his profile this year, and his breaking balls have given opposing hitters fits. They are averaging .333 against his sinker, which has been more hittable this year than in years past, but with a robust arsenal of five pitches, he has plenty of weapons to get the outs he needs.

Statistical Nugget: Ashby has thrown 83 curveballs this year. Opposing hitters have whiffed 70.8% of the time while failing to record a single hit.

Jacob Misiorowski
5 GS, 27 ⅔ IP, 3.58 ERA, 3.28 FIP, 34.2 K%, 8.5 BB% 
Misiorowski dazzled the big leagues in his rookie year, but so far, it looks like his sophomore campaign is going to take his player stock to new heights. His strikeout rate (38.1%) and whiff rate (38.8%) are both in the 99th percentile, and the only qualified pitcher with a higher average fastball velocity is Mason Miller.

His slider has shown major improvement over last year, generating less hard contact and serving as a more effective put-away pitch in two-strike situations. His curveball has taken a similar step forward but the star of the show is still his heater, which has a whiff rate of 47.1%.

Statistical Nugget: This year, Misiorowski has a zone swing and miss rate of 29.1%, the highest among all qualified pitchers.

Pitcher of the Month — Kyle Harrison
4 GS, 18 ⅔ IP, 2.41 ERA, 3.08 FIP, 28.9 K%, 9.2 BB% 
Harrison is the latest victory in a long list of successful trade deals executed by the Brewers under Matt Arnold. After three unremarkable seasons with the Giants and Red Sox, it took Milwaukee just a handful of starts to unlock his exceptional upside as a starting pitcher. After 29 ⅔ total innings of work this season, he has a 2.12 ERA and a 2.87 FIP.

He has been known for his fastball since he was a top prospect in San Francisco’s system, but this is the first year that his slurve has been a viable secondary offering. The shape hasn’t changed much, but it has been located far better this year, ending up outside of the zone and limiting meaningful contact.

The Brewers getting the best out of a discarded pitcher is a tale as old as time, but Harrison, who’s under club control until 2031, is looking like he’ll be a core component of Milwaukee’s rotation for the foreseeable future.

Statistical Nugget: By pitching run value, Kyle Harrison currently has the most valuable slurve in all of MLB.
