The Milwaukee Brewers called up their #4 overall prospect and #1 pitching prospect, Jacob Misiorowski, to the majors, which is an indication of a heavy investment into their rotation. 

The 23-year-old righty is ranked #68 overall by MLB Pipeline and has electric stuff and tantalizing upside in his minor league career, and therefore is highly praised addition to the Brewers' rotation. 

Here, we examine Misiorowski's prospect status, statistical trends, and what fantasy baseball owners can anticipate about his electrifying young starter.

 

Jacob Misiorowski Prospect Status

Jacob Misiorowski, a 6'7" right-hand starter, has made waves in the Brewers organization since being drafted during the second round of the 2022 MLB Draft from Crowder College. His combination of a blazing fastball, sharp breaking pitches, and improving command has cemented his status as Milwaukee’s top pitching prospect and a top-100 talent league-wide. 

Misiorowski’s rapid rise through the minors, coupled with his dominant stuff, has scouts and analysts buzzing about his potential to become a frontline starter or high-leverage reliever. His elevation to the big leagues in 2025 suggests the Brewers view him as an available contributor, possibly even as a starter, but his use may be contingent upon team requirements.

 

Jacob Misiorowski Stats

The minor league career of Misiorowski contains some outstanding aspects, like strikeouts, and certain areas where he has struggled. The below analysis is derived from available statistics throughout the different levels:

2022 (A, Age 20): In a short 1.2-inning debut, Misiorowski was loose on a 16.2 K/9 but operated on a 37.8 BB/9, suggesting initial control problems. His 5.40 ERA and 14.65 FIP were based on tiny samples and inflated accordingly, but his 66.7% ground ball rate gave us a glimpse of how he could get weak contact.

2023 (A, A+, AA, MiLB Combined, Age 21): Misiorowski was dominating over 71.1 innings with a 13.88 K/9 and 3.41 ERA. His 5.30 BB/9 walk rate remained an issue, but he held the home run at bay (0.25 HR/9) and had a 73.6% LOB%. His performance did get better as he moved up levels, although his 5.57 Double-A ERA was covering up some pains of growth.

2024 (AA, AAA, MiLB Combined, Age 22): Misiorowski pitched 97.1 innings with an 11.74 K/9 and a 3.33 ERA. His walk rate (5.55 BB/9) and home run rate (0.74 HR/9) were in check, and his .234 BABIP and 74.9% LOB% indicated his ability to strand baserunners. At Triple-A, he split time in a hybrid role, appearing in 14 games (2 starts) with a 2.55 ERA, and one save.

2025 (AAA, Age 23): In 63.1 innings, Misiorowski had a 11.37 K/9, 4.41 BB/9 and carried an ERA of 2.13. With his 0.57 HR/9 and 83.9% LOB%, Misiorowski showed above-average stuff well suited for the top minor league level and a potential MLB rotation.

The well-rounded arsenal from a rotation perspective, helping Misiorowski reduce his walk rate and well-hitting contact really put him in the high-upside discussion, although all of this must be kept in touch with his BB/9 numbers.

 

Jacob Misiorowski Fantasy Baseball Projections

For fantasy baseball owners, Jacob Misiorowski is a high-risk, high-reward prospect who can help immediately. His upper-echelon strikeout stuff (forever over 11 K/9) makes him roster-worthy across the board, particularly in keeper and dynasty leagues where his ceiling is enormous in the long term. With his high-90s fastball that has touched triple digits, along with a slider that serves as an out punch, he has the material to rack up strikeouts against MLB hitters.

However, there are risks. Misiorowski’s walk rates (4.41 BB/9 in 2025) could lead to inconsistent outings, especially as he adjusts to MLB lineups. Managers should temper expectations for his ERA and WHIP early on, as control issues may persist against savvier hitters.

In dynasty leagues, Misiorowski is a top-tier pitching prospect with ace potential, comparable to some of the elite young arms like Hunter Greene. In re-draft situations, he's a gritty strikeout speculative add for managers needing strikeouts, with 10+ K/9 ceiling on a partial-season scale. Watch his role closely—if he gets into the rotation, his value can reach astronomical proportions. Stash him right now in deep benches or prospect positions in leagues as his first game might cause a roster frenzy.

In summary, Jacob Misiorowski’s call-up is a game-changer for the Brewers and fantasy managers alike. His electric stuff and strikeout prowess make him a tantalizing addition, but his control issues warrant caution. Grab him in dynasty formats and consider him a high-upside flier in redraft leagues, with the potential to be a fantasy star by season’s end.
