2026 Fantasy Outlook
Misiorowski was called up by the Brewers in June and posted a 2.81 ERA, 0.90 WHIP and 33:11 K:BB in his first five MLB starts, which was enough to get him to the All-Star game as a controversial replacement. The rest of the right-hander's rookie campaign wasn't quite so rosy, as he finished the regular season with a 4.36 ERA across 66 innings. However, Misiorowski put his best foot forward in the playoffs with just two earned runs allowed in three outings, as he showcased his potential on the big stage. Milwaukee was cautious with the flamethrower's workload (he threw more than five innings just three times in 18 MLB appearances, including the playoffs), but he still totaled 141.1 frames between Triple-A and the majors. That sets up Misiorowski for a solid starter's workload in 2026, though the Brewers still aren't likely to fully cut him loose. Despite the minor volume concerns, Misiorowski's strikeout potential (11.9 K/9) makes him a valuable fantasy commodity, though there's also some potential volatility given his lack of MLB track record and history of walks in the minors. The right-hander had a 4.2 BB/9 during his rookie campaign (compared to a 5.4 mark during his minor-league career), which if he can maintain, should allow him to be successful at the MLB level given his elite stuff.

First to 100 Ks in dominant win
PMilwaukee Brewers
May 25, 2026
Misiorowski (5-2) earned the win Monday against the Cardinals, allowing one run on two hits and one walk with 12 strikeouts across seven innings.
Analysis
Dominance has become the expectation for Misiorowski, as the Cardinals' lone run in the sixth inning was the first run against Misiorowski in the month of May. His 12 strikeouts were a new season-high and made Misiorowski the first pitcher to reach 100 strikeouts in 2026. He's posted an incredible 49:6 K:BB across 31.1 innings this month, while allowing just one run on 11 hits. One would be hard-pressed to find a starter better than Misiorowski through the first two months of the season. On the year, he owns a microscopic 1.83 ERA and 100:19 K:BB across 64 innings. Misiorowski is in the 98th percentile or better in fastball velocity (99.7 mph), whiff rate (39 percent) and strikeout rate (39.3 percent).

Past Fantasy Outlooks
2025
2024
2023
It remains an open question as to whether Misiorowski will ever throw enough strikes to be a big-league starter. The 6-foot-7 righty's stuff is not in question, particularly his upper-90s fastball and devastating slider, both of which are 70-grade pitches at their best. Misiorowski logged a 3.50 ERA, 1.28 WHIP, 105 strikeouts and 50 walks in 79.2 innings across 19 starts at Double-A before he worked primarily as a reliever over 17.2 innings at Triple-A to close the year. If Milwaukee thought Misiorowski was ready to be a major postseason weapon, he likely would have been added to the 40-man roster in September, but that move was never made. He actually made progress last season at Double-A, as he had eight starts with three or more walks in his first 10 starts and two starts with three or more walks in his next nine starts -- his only two 10-strikeout starts also came in that June/July run of improvement. Misiorowski still has a faint chance of making it as a rare starter who is good for 200-plus strikeouts per year, but a future in high-leverage bullpen situations is probably more likely at this point.
Misiorowski has frontline starter upside and all the stereotypical risk factors that get associated with young, lanky flame throwers. The 6-foot-7 righty missed the final month of the season with arm fatigue, can touch triple digits with his fastball and had walk rates over 13 percent at High-A (13.2 BB%) and Double-A (15.0 BB%). He also has one of the best sliders in pro ball and the type of strikeout upside that's hard to come by. It would require rapid development for him to get his command and pitchability to a point where he is ready to have success as a big-league starter in 2024. He built up to 71.1 innings but only threw five-plus innings four times in 20 starts. Misiorowski is the exact type of pitching prospect the Brewers may opt to break in as a high-leverage reliever before stretching him out the following season, as they did with Corbin Burnes and Brandon Woodruff.
Misiorowski was a deep cut in pre-draft coverage, but by the fall, he was one of the buzziest pitchers in the class. It's all about the upside with Misiorowski, a Crowder JC product (the same JUCO that produced Aaron Ashby), who can touch 99 mph with his fastball and has extremely high spin rates across the board on his three-pitch mix. His upper-80s slider is a devastating offering, and his curveball is a great third pitch. The lanky 6-foot-7 righty lasted until the 63rd pick, but Milwaukee gave him a bigger draft bonus ($2.35 million) than they gave to first-rounder Eric Brown Jr., so Misiorowski should be treated like a first-round talent. Several teams hoped to go over-slot to land Misiorowski in this range, and the Brewers were the most aggressive team. His command/control will determine whether he is a high-strikeout starter or a late-inning reliever. He doesn't turn 21 until April and will probably require more development in the minors than the other top college starters in this class.

Latest Fantasy Rumors
Extension talks not progressing
PMilwaukee Brewers
November 29, 2025
The extension talks between Misiorowski and the Brewers have yet to gain traction, according to Curt Hogg of the Milwaukee Journal Sentinel.
Analysis
The Brewers have made the long-term signing of Misiorowski a priority, but talks between the two parties haven't progressed much. Hogg even mentioned that those talks "have not occurred with any real momentum yet," so it's uncertain whether there will be an agreement anytime soon. Misiorowski made the 2025 All-Star Game as a rookie, and even though he endured some regression in the second half of the campaign, he still posted a 4.36 ERA across 66 regular-season innings.
