Misiorowski threw five scoreless innings in a game with Double-A Biloxi on Sunday. He allowed two hits and posted an 8:4 K:BB in the contest.
Misiorowski was tagged for four earned runs over 4.1 innings in his first start of the season, but he has allowed only three runs in 19.0 innings since, and since the start of that stretch he owns a 1.42 ERA, 1.11 WHIP and 29:14 K:BB. The walk rate and a handful of wild pitches over the same span indicate the control could use some work, but opposing hitters are having trouble making contact against one of Milwaukee's top pitching prospects.
Misiorowski (arm) has resumed a throwing program, Adam McCalvy of MLB.com reports.
Misiorowski didn't make an appearance after Aug. 15 due to right arm fatigue, but it would appear he's moved past that. The 21-year-old was one of the biggest pitching prospect breakouts in all of the minors in 2023, collecting a 3.41 ERA and 110:42 K:BB over 71.1 innings between Low-A Carolina, High-A Wisconsin and Double-A Biloxi. It's possible he could push to debut at some point in 2024 if he stays healthy and continues to progress.

Brewers' Jacob Misiorowski: Lands on injured list
Rotowire
Double-A Biloxi placed Misiorowski on its 7-day injured list Saturday due to arm fatigue, Adam McCalvy of MLB.com reports.
Per the report, "Initial tests did not prompt significant concern about structural damage, but out of caution, the Brewers have shut Misiorowski down for the time being." With that in mind, Misiorowski is facing an extended absence, but according to Brewers general manager Matt Arnold, there's still a chance the hard-throwing 21-year-old could find himself in the big-league bullpen before the campaign comes to a close.
The Brewers promoted Misiorowski from High-A Wisconsin to Double-A Biloxi on Monday, Curt Hogg of the Milwaukee Journal Sentinel reports.
After striking out the side in a head-turning performance during the All-Star Futures Game on July 8, Misiorowski made one final tune-up outing at the High-A level over the weekend before ultimately earning the call to Biloxi. The flame-throwing right-hander will join his third affiliate of the season after he began the 2023 campaign at Single-A Carolina before moving to the Midwest League in early June. Over his six starts at Wisconsin, Misiorowski turned in a 1.90 ERA, 1.25 WHIP and 28:14 K:BB across 23.2 innings.
Misiorowski was promoted Tuesday from Low-A Carolina to High-A Wisconsin, Curt Hogg of the Milwaukee Journal Sentinel reports.
Misiorowski earned the promotion after delivering a 3.04 ERA, 0.83 WHIP and 46 strikeouts through 26.2 innings (nine starts) this season in the Carolina League. Selected in the second round of the 2022 MLB Draft, the fast-rising 21-year-old is the highest-rated pitching prospect in the Brewers' system.

Brewers' Jacob Misiorowski: Making mark at Single-A
Rotowire
Misiorowski posted a 1.00 ERA, 0.44 WHIP and 14:3 K:BB in nine innings over his last two starts with Single-A Carolina.
Misiorowski has been brought along slowly in his first full professional season, but he has steadily built up his innings, and his last two outings showed why he is thought of highly by prospect evaluators. Misiorowski turned 21 years old in April, so he will have a chance to move up the ranks at some point this summer.
