Milwaukee Brewers
Bruce Zimmermann has thrown 6,117 pitches that have been tracked by the PITCHf/x system between 2020 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (90mph), also mixing in a Curve (81mph), Change (82mph), Slider (86mph) and Sinker (90mph). He also rarely throws a Cutter (87mph).
In 2025, compared to other LHP:
Their fourseam fastball has less armside movement than typical, has some natural sinking action, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their curve generates fewer whiffs/swing compared to other pitchers' curves, is much harder than usual, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. Their change dives down out of the zone and generates more whiffs/swing compared to other pitchers' changeups. Their slider has primarily 12-6 movement, generates fewer whiffs/swing compared to other pitchers' sliders, is much harder than usual and results in somewhat more groundballs compared to other pitchers' sliders. Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, generates a high number of swings & misses compared to other pitchers' sinkers, has less armside run than typical and has some natural sinking action. Their cutter (take this with a grain of salt because they've only thrown 11 of them in 2025) has heavy sink, is an extreme flyball pitch compared to other pitchers' cutters, generates more whiffs/swing compared to other pitchers' cutters and has little cutting action.
