2025 Fantasy Outlook
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 tossed 3.2 scoreless, no-hit innings of relief for Triple-A Nashville on Saturday. He struck out four and walked four.
ANALYSIS
The 23-year-old righty's second outing of the season looked a lot like his first, when he allowed one hit over five scoreless frames while recording a 7:3 K:BB in a start. Misiorowski -- one of Milwaukee's top pitching prospects -- has proven he can miss bats, posting a 12.6 career K/9 rate in the minors. He also owns a 5.8 BB/9 rate, however. Misiorowski figures to make his big-league debut at some point this season, but the Brewers are still hoping to see him display better control, and that could determine whether or not they give him a chance to start or use him out of the bullpen at the top level.

Past Fantasy Outlooks
2024
2023
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
Could debut as reliever
PMilwaukee Brewers  AAA
June 7, 2024
Curt Hogg of the Milwaukee Journal Sentinel believes Misiorowski could make his MLB debut this season, though it's likely to be in a bullpen role.
ANALYSIS
The 22-year-old is the Brewers' top pitching prospect and has a 2.98 ERA through 11 starts at Double-A Biloxi this season, but he's not likely to be a solution for the club's injury issues in the rotation. Misiorowski's swing-and-miss stuff is apparent with a 12.6 K/9 at Double-A this year, but a 6.8 BB/9 illustrates the need for him to continue his development in the minors.
