Jalen Beeks has thrown 7,519 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 Fourseam Fastball (94mph) and Change (89mph), also mixing in a Slider (84mph). He also rarely throws a Cutter (87mph).
In 2025, compared to other LHP:
Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and has well above average velo. Their change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups and has some natural sink to it. Their slider results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their cutter (take this with a grain of salt because they've only thrown 5 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has some natural sink.
