Merry Mis-mas: Jacob Misiorowski's 5 Greatest Moments in an Extraordinary First Year in the Majors

It's easy to overhype a great prospect, or a player who has a tremendous rookie season. It's also easy to get jaded, and to dismiss the alleged greatness of something when the world seems to be juicing it up too much. Let's try to find a sweet spot in the middle together, shall we? Jacob Misiorowski will celebrate the one-year anniversary of his debut Friday by making his 32nd appearance in the big leagues, counting his three outings last October. He's still only pitched 156 innings at the game's highest level. However, he's already left an indelible imprint on his team, his adopted city and his sport. Let's talk about how. Here are the five best moments and performances of Misiorowski's young career.

1. Starting His Career with 11 No-Hit Innings
Everyone knew Misiorowski's name even before he debuted. but this was not like the so-called Strasmas of June 2010, when Nationals phenom Stephen Strasburg took the bump for the parent club for the first time and mowed down 14 Pirates in seven innings. Strasburg had been the No. 1 pick in the MLB Draft just a year earlier. Misiorowski was a bit of a novelty item: a junior-college find by Brewers scouts who threw exceptionally hard but often didn't know where it was going. He'd turned a corner with his control in the minors, but would he have the command to dominate the best hitters on Earth?

He immediately answered that question, with extreme prejudice. He only pitched five innings that first day against the Cardinals, with the crowd at Uecker Field roaring and thrumming with the electricity he put into the atmosphere, but he didn't give up a hit. He walked four and struck out five, before leaving after a bizarre ankle-wobble that was just enough to convince Pat Murphy to play it safe.

That was a stunning debut, and immediately, the baseball world was abuzz with talk about The Miz. But what he did a week later turned the dial up to 11—literally. On a hot night in Minneapolis, with a Brewers-leaning Friday night crowd that was every bit as pitched toward excitement as the last one, Misiorowski fired another six no-hit innings against the Twins. In fact, this time, he was perfect through six frames: 18 batters faced, six strikeouts, zero baserunners. Murphy felt he'd earned a shot at the 7th, and the night ended quickly with a walk and a home run, but the story of the game was unchanged. Misiorowski wasn't just a good and unusual pitching prospect. He announced himself, immediately, as one of the best pitchers in the sport.

2. The All-Star Nod
A huge kerfuffle erupted in the baseball world when Misiorowski was named to the National League All-Star team after making just five appearances in the majors. Given the scale of that internet scrap, one side or the other was going to have to look stupid at the end. It's the naysayers who sound like numbskulls, with the benefit of hindsight.

It was certainly unusual to tack a player into the All-Star Game after so brief a stint in the bigs, but Misiorowski acquitted himself well on all fronts. He handled some tedious questions with his usual, affable shrug. He fired a scoreless inning in the game itself. It was the first instance in which he was asked to be the face of the league, in a sense, though not the last. He handled it well, on the field and off.

3. The Bounce, the Fist Pump, the Tide Change
It's easy to forget this now—the Brewers' triumph feels almost inevitable, looking back on it—but Misiorowski was called upon in Game 2 of the NLDS at a precarious moment. The Brewers had blown the Cubs' doors off in Game 1, but it was 3-3 after two innings the next day. Chicago had gotten to Aaron Ashby, and Nick Mears was brought in only to bridge a gap and get out of the second. The series could easily have tipped in Chicago's favor.

Instead, Misiorowski (with the help of the Brewers offense) shoved it the other way. He held Chicago scoreless over three innings, and the way he did it—twice topping 104 MPH in raw velocity, and with enormous intensity and passion—ended up turning the tide in Milwaukee's favor. He finished his first inning of work by running to the base to record the putout himself on a grounder he fielded, and then bounced off the field, roaring and pumping his fists. The crowd went berserk. Cubs fans (in a different way) went berserk. That was just the first of Misiorowski's innings, though. To go out after that display of catharsis and record two more strong frames showed his poise—the shark-eyed dominator that lies beneath the jubilant and sometimes disarming exterior.

It's worth remarking and remembering, too, that the Brewers trusted Misiorowski with that assignment on purpose, even after he struggled to the finish line in the regular season. Some even speculated that he might not be on the Division Series roster. Seeing his makeup for what it is, as well as trusting the stuff, the Brewers leaned hard on him, instead. He got the win that night, and again in Game 5, when it was four innings of one-run ball. His charisma, as well as his incredible talent, was on full display.

4. Keeping a Little Bit of Pride
Alas, the Brewers were not going to win the NLCS. Things needed to break their way, and they just didn't. Having worked at the end of the Cubs series, Misiorowski didn't take the mound again until Game 3 of the following series, on the road at Dodger Stadium. The Crew lost, but Misiorowski gave an even bigger audience—and a national media quick to dismiss the Brewers and crown the Dodgers as the cream of the crop for a second straight year—an eyeful of what the smallest market in the league can produce. He pitched five innings, giving up two runs on just three hits and a walk. He struck out nine, and left Shohei Ohtani so impressed (read: frustrated) that he gushed a bit about him to the Japanese press afterward.

That moment made Misiorowski a global sensation. This spring, Japanese reporters showed up at Brewers camp to check in on the team, with special attention paid to Misiorowski. Step by step, over the first handful of months of a very young career, he blossomed from a second-round pick and a lottery ticket of a prospect into a full-fledged superstar.

5. The Streak
As electrifying as Misiorowski was in 2025, however, he wasn't completely dominant. There were periods of real ineffectiveness, which is why he was in danger of not making the postseason roster (at least to outside eyes). There were a lot of walks. Entering 2026, it was fair to hope he might become the ace of the squad, but not quite reasonable to expect it.

And then, very quickly, any doubt was swatted away, like a fly slowed down by too much nectar and buzzing too close to an ear. Misiorowski showed up in camp carrying more weight—good weight. He was only listed 4 pounds heavier in this year's Brewers media guide (201) than in last year's (197), and Brewers media relations ace Mike Vassallo takes great pride in the accuracy of his reported weights, but Misiorowski is simply thicker this year: thicker in the legs, thicker in the arms. He remains slender, but he's more physically mature. Injuries helped it happen, but very early in camp, it was clear he would be the Brewers' Opening Day starter. He asserted himself.

Misiorowski struck out 11 in five innings on Opening Day and was similarly impressive the next time out, but early in the year, he consistently talked about feeling unable to open it all the way up—to throw as hard and as freely as he felt was possible—because of a mechanical issue in his lower half. It was easy to raise an eyebrow at this. No one throws as hard as Misiorowski. It was most likely that he himself couldn't throw any harder than he was.

And then he did. After four starts early on in which he sat 98-99, Misiorowski's average heater has been at least 99.7 MPH in every outing since, culminating in averaging 101.3 last weekend in Colorado. That's just the actual velocity. His release extension has also ticked up over the same period.

As a result, we've seen a pitcher against whom every hitter on Earth is essentially helpless. Aaron Judge got to try hitting this version of Misiorowski; he came away muttering about the best fastball he'd ever seen. Two pitches Misiorowski threw to Judge had a perceived velocity over 106 MPH, after adding the extension to sheer velocities over 103.

With a keen sense of occasion, Misiorowski pitched against the Cardinals at home late last month and threw himself an early anniversary party. Once again, the Cardinals had no hits through the first five innings. This time, Misiorowski stuck around through seven, and he eventually gave up a run, but that was the first tally he'd surrendered in 30 innings of work. He's pitched twice more since, adding seven more frames each time, and the only run he's allowed in that span was unearned.

In one sense—blending the utterly unprecedented velocity with the command he's found and a deeper arsenal, and considering the superb results—we're watching a legitimate candidate for the best pitcher in baseball history. There's no credible argument that anyone else is the best pitcher in the game at this moment, despite the brilliance of Cristopher Sánchez. Misiorowski is overpowering, cocksure, intelligent, and driven. Sixteen months ago, the pitcher he'll face Friday night—the Phillies' Andrew Painter—was a more famous name among prospect gurus. One year ago, he was a slightly skinny kid who didn't have his manager's full trust. Since then, he's made the fastest ascent toward baseball immortality this side of Mike Trout's historic rookie season—or, if you prefer to compare apples to pitchers, Strasmas.

Merry Mis-mas, everyone.
