Chicago Cubs
Brad Keller has thrown 14,331 pitches that have been tracked by the PITCHf/x system between 2018 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Cutter (97mph) and Slider (87mph), also mixing in a Sinker (96mph) and Splitter (92mph). He also rarely throws a Curve (85mph).
In 2025, compared to other RHP:
Their cutter is thrown at a speed that's borderline unfair, explodes on the hitter and has little cutting action. Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has short glove-side cut, is much harder than usual and has some two-plane movement. Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and is blazing fast. Their splitter is thrown extremely hard and is an extreme flyball pitch compared to other pitchers' splitters. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2025) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite and has primarily 12-6 movement.
