Jacob Misiorowski, the Milwaukee Brewers’ right-handed pitcher from Grain Valley, Missouri, is known for his 103mph fastball, but he’s still working to perfect it amidst other pitches. Manager Pat Murphy emphasizes that having a fast pitch doesn’t guarantee success; rather, it’s about commanding what you can command.
Misiorowski showcased his skills this season at Triple-A Nashville, striking out 80 and allowing only 38 hits in 63 1/3 innings. However, his biggest challenge lies in reducing walks – an area where he trails some notable MLB stars. To address this, Misiorowski has made significant improvements, lowering his walk rate to 4.4 per nine innings.
The Brewers have been instrumental in helping him develop his craft, and the organization is confident in his potential. Despite struggling initially in spring training games, Misiorowski worked tirelessly on all his pitches, setting up his blazing fastball. The 23-year-old needs to refine his release point to consistently throw strikes, but with time, he’s expected to mature.
Fans have taken notice of the big prospect, and his nickname remains a topic for discussion. “Swing And Mis” or perhaps “Big Jake” could be fitting monikers for the towering right-hander. As Misiorowski continues to hone his skills, fans can’t wait to see him succeed in Milwaukee.
