Drey Jameson has thrown 3,873 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Slider (87mph) and Fourseam Fastball (99mph), also mixing in a Change (90mph) and Sinker (96mph). He also rarely throws a Cutter (91mph).
In 2025, compared to other RHP:
Their slider generates a high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, is much harder than usual, has primarily 12-6 movement and has some two-plane movement. Their fourseam fastball is thrown at a speed that's borderline unfair and has some natural sinking action. Their change is thrown extremely hard, dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their sinker is basically never swung at and missed compared to other pitchers' sinkers, is blazing fast, has slight armside run and has some natural sinking action. Their cutter (take this with a grain of salt because they've only thrown 4 of them in 2025) has heavy sink, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has well above average velo.
