Up Next: Jacob Misiorowski

After throwing six innings of two-run ball tonight, and five hitless in his debut last week, Jacob Misiorowski has been thrust into the spotlight, and national attention has flocked his way. Fans all across the league have tuned in to the young righty’s starts, eager to catch a glimpse of Milwaukee’s budding ace.

Originally taken in the second round of the 2022 draft, Misiorowski dominated his time in the minor leagues. The 23-year-old pitcher owned a 3.04 ERA and 1.19 WHIP in 233.2 innings, while racking up 320 punchouts. MLB's current #66 prospect, Misiorowski was called up on June 10 when his promotion could wait no more. After he dazzled tonight, it’s clear that he’s already an MLB caliber pitcher.

Working to guide Misiorowski’s dominance is his stature, which stands at 6-foot-7, 197 pounds. While his size intimidates on the mound, it’s his arsenal that strikes fear into opposing hitters. He works with a simple mix, relying on a 4-seam, slider, curveball, and changeup. Misiorowski’s mix isn’t all that typical though, since he’s one of MLB’s hardest throwing pitchers.

Today Misiorowski’s fastball topped at 102.1 MPH, while never dipping below 97.4 MPH. He averaged 100.4 MPH today, placing him among MLB’s top arms. Although he isn’t yet qualified for velocity leaderboards, the heater speaks for itself. In 84 opportunities, opposing batters have recorded zero hits against the pitch, while swinging and missing over 10 times. Misiorowski's 7.5 foot extension proves deadly, causing his pitches to appear faster than they are, in turn overpowering the hitter. 

What truly sets Misiorowski apart is his slider, which topped at 96.7 MPH today. That’s roughly the same as Tarik Skubal’s average fastball velocity in his Cy-Young-winning 2024 season (96.8). The pitch is so fast that broadcasts have picked it up as a cutter, as seen in this matchup against Masyn Winn (watch here). A DeGrom-esque pitch, Misiorowski’s slider is bound to keep opposing hitters off balance. While his lone blemish of the night came off a slider, he recorded five whiffs and six called strikes with the pitch, good for a 34 CSW% (thrown 32 times). 

The changeup and curveball also worked for Misiorowski tonight, although they appeared only minimally (changeup twice, curveball 11 times). He touched 94.4 MPH with the changeup, while the curveball maxed out at 88.8 MPH, and recorded a whiff on each, No changeups or curveballs being put into play by Twins hitters.  

While the sample size is small and there isn’t much to analyze yet, Misiorowski’s power profile gives the Brewers something to be excited about. If he can stay healthy and keep hitters off balance as he has in these first two career starts, we could be seeing the blossoming of something special.
