Summary
- Rookie Jacob Misiorowski hits 104 MPH in first MLB postseason pitch
- Misiorowski's debut averages over 102 MPH, joining elite company
- Brewers gain a power weapon that could swing the playoff series

On October 7th, 2025, the Milwaukee Brewers unleashed one of baseball's most electric arms on the national stage. Rookie Jacob Misiorowski, making his first appearance in the MLB postseason, stepped onto the mound at American Family Field in Game 2 of the 2025 NLDS and immediately lit up the radar gun.
Misiorowski's first pitch registered at 103 MPH, instantly making headlines across the league. Facing Kyle Tucker in his debut at-bat only heightened the intensity of the moment. The young right-hander continued to build momentum, with his next two pitches clocking in at 103.4 and 103.7 MPH, drawing audible gasps from the crowd.
The instant velocity put Misiorowski into elite company, as only a handful of pitchers have reached 104 MPH in postseason play since Statcast began tracking in 2008. The Brewers' 23-year-old rookie did it in his very first appearance, averaging over 102 MPH in the opening frame.
This performance has already become one of the defining images of the 2025 MLB postseason. For the Brewers, it signals the arrival of a potential October difference-maker and gives their bullpen a power weapon that could swing the series. Fans and media alike are now watching to see what Misiorowski does next.
