A Historic Milestone: All-Star After Only Five Games
Rookie pitcher Jacob Misiorowski has achieved what no Major League Baseball starter has ever done before: earning All-Star recognition after just five games. The 23-year-old Milwaukee Brewers sensation was announced as a replacement for Chicago Cubs’ Matthew Boyd, who will be inactive due to a scheduled start this weekend.
With a fastball that consistently reaches triple digits and a calm presence on the mound, Misiorowski has not only met expectations—he’s shattered them. He’s now the fastest player in modern MLB history to receive All-Star honors, a feat that cements his status as one of the most exciting young talents in professional baseball.
Setting the Standard: Record-Breaking Debut
Since being called up last month, Misiorowski has compiled one of the most dominant opening stretches in MLB memory:
- 11 consecutive no-hit innings to start his career
- A 4–1 win-loss record
- An ERA of 2.81
- An average fastball speed of 99.3 mph, with 89 pitches clocked at 100+ mph
According to MLB Stats, no starting pitcher in modern baseball—dating back to 1900—has matched this no-hit streak at the beginning of a career.
“I honestly have no words,” Misiorowski said after the announcement. “It’s an honor… I just wanted to say thank you for all the help you guys have given me.”
Breaking a 125-Year Record
Before Misiorowski, Paul Skenes of the Pittsburgh Pirates was the fastest modern All-Star pitcher, selected after 11 games. Prior to that, Mark Fidrych (1976), Hideo Nomo (1995), and Dontrelle Willis (2003) reached All-Star status in their 13th MLB appearances.
But none came close to five games.
Milwaukee manager Pat Murphy revealed the news just before Friday’s national anthem, then formally told the team after their 8-3 win over the Washington Nationals. The clubhouse erupted in applause as Misiorowski thanked teammates for their mentorship during his whirlwind debut.
Rookie All-Star Comparisons
| Player | Team | All-Star Selection After | Year |
| Jacob Misiorowski | Milwaukee Brewers | 5 games | 2025 |
| Paul Skenes | Pittsburgh Pirates | 11 games | 2024 |
| Mark Fidrych | Detroit Tigers | 13 games | 1976 |
| Hideo Nomo | LA Dodgers | 13 games | 1995 |
| Dontrelle Willis | Florida Marlins | 13 games | 2003 |
A Star Among Giants
Misiorowski’s dominant fastball, which has topped out at 103 mph (166 kph), makes him not only a rookie to watch but a serious threat to veteran hitters. His command and pitch diversity have drawn comparisons to top-tier pitchers despite his limited experience.
The Brewers’ front office had long signaled that Misiorowski was a top prospect. But the speed with which he’s ascended to All-Star status has stunned even seasoned analysts.
“To break a record this old tells you all you need to know,” said an MLB scout quoted by ESPN.
Elsewhere in the League: Cal Raleigh’s Record Slam
In other All-Star break headlines, Seattle Mariners slugger Cal Raleigh hit two more home runs on Friday—one of them a grand slam—bringing his season total to 38. This sets a new American League record for most home runs before the All-Star break, putting Raleigh just one behind Barry Bonds’ MLB record.
“Trying to go hit home runs is probably not going to help me,” Raleigh said. “I’m going to stay within myself.”
His performance propelled the Mariners to a commanding 12–3 win over the Detroit Tigers, reinforcing Seattle’s dominance in the AL.
What’s Next for Misiorowski?
Misiorowski’s inclusion in the All-Star Game lineup, which takes place Tuesday, will place him on a national stage alongside seasoned stars. Analysts believe this could be the start of a Rookie of the Year campaign—or even Cy Young consideration if he continues to dominate in the second half of the season.
The Brewers are currently in strong playoff contention. With Misiorowski in the rotation, their odds have improved, both statistically and in terms of clubhouse momentum.
