Brad Keller has thrown 12,026 pitches that have been tracked by the PITCHf/x system between 2018 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (87mph) and Cutter (93mph), also mixing in a Splitter (90mph), Sinker (92mph) and Curve (83mph).
In 2024, compared to other RHP:
Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has exceptional depth and has short glove-side cut. Their cutter is thrown at a speed that's borderline unfair, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters, generates a high number of swings & misses compared to other pitchers' cutters and has good "rise". Their splitter is thrown extremely hard, generates a high number of swings & misses compared to other pitchers' splitters and is an extreme flyball pitch compared to other pitchers' splitters. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 13 of them in 2024) generates more 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.
