Misiorowski reaches 102 mph, allows no hits in electric MLB debut

June 12th, 2025

MILWAUKEE -- Of course Jacob Misiorowski’s first pitch in the Major Leagues was a fastball. It found the strike zone at 100.5 mph, making it the second-fastest fastball thrown by a Brewers starter in the pitch-tracking era, just a few clicks below Trevor Megill’s 100.7 mph as an opener in 2023.

That mark didn’t take long to fall. Misiorowski’s second pitch was 101.8 mph. His fifth pitch was 102.2 mph. His 78th pitch was 101.1 mph to complete a fifth hitless inning.

But in the sixth, while making his 81st pitch, Misiorowski (Brewers No. 4 prospect, MLB No. 68) felt his right quadriceps and calf cramp. As if that wasn't enough, he turned his right ankle after the follow-through, and while Misiorowski and the Brewers quelled any concern about those ailments impeding his next start, it made for an unsatisfying ending to a remarkable introduction for the 23-year-old, 6-foot-7 flamethrower in Thursday night’s 6-0 win over the Cardinals at American Family Field.

“Of course I don’t want to leave like that. I felt like I could have kept going,” Misiorowski said. “I cramped up, and stuff happens. I saw the picture and it looks bad, but it feels good, it feels great.”

For most of the night, it was great.

“I’ve been playing this day out in my head forever,” Misiorowski said. “I thought I was going to give up a few hits, get your welcome to The Show. But I kind of rolled with it, and now we’re here.”

Making Milwaukee’s most highly anticipated pitching debut since at least 2017, when Josh Hader started slinging fastballs out of the bullpen, or perhaps as far back as the day Olympic hero Ben Sheets arrived in 2001, Misiorowski worked five-plus innings without allowing a hit or a run, worked around four walks and struck out five before his abrupt exit in an outing that was every bit as electric as advertised from the very first pitch.

By night’s end, he had fired 14 pitches at 100.0 mph and above, the fourth most by a starter in an MLB debut in the pitch-tracking era. Before Thursday, all of the Brewers’ starters had thrown eight triple-digit pitches in that time, and six of them belonged to Megill as an opener. The only true starters to do it both registered exactly 100.0 mph with exactly one pitch: Wily Peralta in 2013 and Brandon Woodruff in '19.

Jacob Misiorowski on his MLB debut
Making Milwaukee’s most highly anticipated pitching debut since at least 2017, when Josh Hader started slinging fastballs out of the bullpen, or perhaps as far back as the day Olympic hero Ben Sheets arrived in 2001, Misiorowski worked five-plus innings without allowing a hit or a run, worked around four walks and struck out five before his abrupt exit in an outing that was every bit as electric as advertised from the very first pitch.

The only true starters to do it both registered exactly 100.0 mph with exactly one pitch: Wily Peralta in 2013 and Brandon Woodruff in '19.

Then came The Miz.

“It’s just incredible pitches coming at you,” said catcher William Contreras, who helped calm Misiorowski when a crowd of 27,687 stirred as the duo walked in from the bullpen. “I know that the velo is there going into it, but it definitely surprises you when you see it consistently coming in 101, 102 [mph]. After that, he had to lock in and not try to do too much. Just pitch.”

Following that brilliant debut in quick order:

Brewers demoted Civale from rotation
Civale demanded trade
He was traded to the White Sox.

The Sox are on the rise. Civale is a nice addition to the Sox staff. They need starting pitchers with experience. Can't hurt.
On second thought, Vaughn could be a nice addition for the Brewers. Not a blockbuster trade, but a pretty even exchange.

joez - good chance Civale is then flipped by the White Sox at the trade deadline. In the meantime Civale can showcase himself every 5 days.

Good chance of that happening TFIR.

Red Sox trade Devers to Giants in stunning blockbuster (source)

24 minutes ago

In a shocking blockbuster over a month before the July 31 Trade Deadline, the Red Sox traded star slugger Rafael Devers to the Giants for Jordan Hicks, Kyle Harrison and more, a source told MLB.com's Mark Feinsand on Sunday evening. The clubs have not confirmed the deal.

Civale is a back of the rotation inning-eater, not much more than that.

Is Junior Caminero the one that got away from the Guardians? Hey, Hoynsie

Hey, Hoynsie: Looking back at the last few years, are there any trades that the Guardians wish that they could have back? — Ryan Moran, Austin, Texas.

Hey, Ryan: Every president of baseball operations or general manager has a personal list of bad deals that they’ve made.

Near the top of the Guardians’ list is the trade of third baseman Junior Caminero to the Rays for right-hander Tobias Myers on Nov. 19, 2021. Caminero, 21, is hitting .256 (77 for 301) with 20 homers, 51 RBI and a .811 OPS this season for the Rays.

Camiinero has a chance to be just the fourth 21-year-old to hit 40 homers in a season. Ronald Acuna Jr., Mel Ott and Eddie Matthews are the only three players to do it.

Myers, who never made it past Triple-A Columbus with the Guardians, is with Milwaukee and won nine games last year.

Sox just shutout the Giants 1 -0. Sox may have foind their closer in Grant Taylor. 8 games, 10 k's, tossing between 95 and 101 mph. Sox will be a spoiler the second half of the season. First half is an audition period moving players in and out. Starting to put together a nice team of unknowns.

Getz seeing Major League core emerging: 'I like the group that we have here'

5:11 PM CDT

CHICAGO -- In looking at the White Sox roster after a 3-1 loss to the Giants Friday, tomorrow or any time in the next month, it’s probably good advice to not commit all the players to memory.

There certainly will be trades between now and the Deadline on July 31.

Luis Aparicio Bobblehead Giveaway is this Sunday!
Maybe not extreme impact deals like All-Star hurler Garrett Crochet to Boston, where four players helping the White Sox in the present and the future were obtained in return. But general manager Chris Getz will be active.

A healthy Luis Robert Jr. remains at the center of potential moves. But anyone from outfielder Mike Tauchman, to right-handed reliever Steven Wilson, to today’s starter Adrian Houser could aid a contending team with a return enhancing the White Sox core at the heart of their latest rebuild.

As for that young core? Well, it’s OK to learn as much as possible about this group, because they are quickly becoming White Sox fixtures.

“I like the group that we have here,” said Getz during an early-week media session. “There could come a point, at some time, that we need to consider something to repurpose the talent on our roster. At this point, I want these guys to really enjoy being with the Chicago White Sox and getting comfortable at the Major League level here.”

What players make up this group? The roster features nine rookies in right-handed pitchers Sean Burke, Wikelman González, Shane Smith, Grant Taylor and Mike Vasil, left-hander Brandon Eisert, catchers Edgar Quero and Kyle Teel and infielder Chase Meidroth, leaving the White Sox tied with Miami for the most rookies in Major League Baseball (per STATS).

Teel, the White Sox No. 2 prospect per MLB Pipeline (No. 24 overall), joined Meidroth and González (No. 15) as part of that Crochet return, along with outfielder Braden Montgomery (No. 4). Montgomery, who has an .829 OPS, 10 homers and 16 doubles between stops at High-A Winston-Salem and Single-A Kannapolis, could be part of the White Sox Major League roster as soon as next season.

Having Teel, who knocked out three hits Thursday in a victory over Arizona, and fellow backstop Quero on the same active roster presents an interesting but pleasant issue for the White Sox, who need to find at-bats and games for both with them staying at catcher. Korey Lee, who turns 27 on July 25, also is behind the plate at Triple-A Charlotte.

So, the White Sox don’t need to make a definitive call on who is No. 1 or No. 2 behind the plate between Teel and Quero in their present state. As Getz mentioned, they are allowing them to develop together.

“We are always looking to do what’s best for this organization in the short term and long term,” assistant general manager Josh Barfield told MLB.com during a recent interview. “There are guys we identified that we feel really good about being part of the future here. We are pretty adamant on those guys being part of this thing going forward.”

That core includes Noah Schultz (White Sox No. 1, overall No. 13) and Hagen Smith (White Sox No. 3, overall No. 26), who are rated the top two left-handed pitching prospects in the game, per MLB Pipeline. Schultz struggled in his second start for Triple-A Charlotte on Friday, walking four, striking out four and allowing five runs in two innings, but still has a trip to the Majors potentially on the 2025 horizon, while Smith returns to the Barons’ rotation Saturday after being out since May 10 for a biomechanics reset and to deal with elbow soreness.

White Sox entire organization is terrible !

Maybe. But after the season they just had, they're rebounding nicely.. right now, they're playing as good or better baseball than the Guardians. I'm interested in seeing how they play in the second half.
