Atlanta Braves
Aaron Bummer has thrown 5,861 pitches that have been tracked by the PITCHf/x system between 2017 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (82mph) and Sinker (93mph), also mixing in a Fourseam Fastball (94mph). He also rarely throws a Cutter (88mph), Curve (82mph) and Change (85mph).
In 2024, compared to other LHP:
Their slider sweeps across the zone, generates more whiffs/swing compared to other pitchers' sliders and has some two-plane movement. Their sinker has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and has well above average velo. Their fourseam fastball has heavy sinking action, generates more whiffs/swing compared to other pitchers' fourseamers and has well above average velo. Their cutter has heavy sink, is an extreme flyball pitch compared to other pitchers' cutters, has slightly above average velo and has strong cutting action. Their curve is thrown extremely hard, is an extreme flyball pitch compared to other pitchers' curves, generates fewer whiffs/swing compared to other pitchers' curves and has slight glove-side movement. Their change (take this with a grain of salt because they've only thrown 12 of them in 2024) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, is an extreme flyball pitch compared to other pitchers' changeups and is slightly firmer than usual.
