Misiorowski Secures Extension

Brewers have secured Misiorowski through five seasons beyond 2026, giving them leverage for an extension.
At 24, he enters his second MLB season, his first full campaign after a 2025 promotion.
Team officials will use any contractual tool and prefer an early extension over arbitration to lock in lower cost.

The mural is visible from the ballpark, linking the cityscape with the Brewers’ brand.
Misiorowski threw a record 105.5 mph pitch despite his front foot sliding.

History

Historical Context

On September 7 1974, Nolan Ryan’s 100.9 mph fastball for the California Angels became the first speed-measured pitch, sparking teams to chase velocity. Since the mid-2000s MLB fastball averages have risen, with 100-plus-mph pitches climbing from 214 in 2008 to 3,848 in 2023. Today Jacob Misiorowski’s 105.5 mph delivery for Milwaukee echoes that legacy.
