The Milwaukee Brewers have 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. His 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 MLB took to its official X (formerly known as Twitter) account to showcase the historic pitch with a video that quickly went viral. The league highlighted just how impressive the debut was with a simple but telling caption.
