Jackson Stephens has thrown 3,850 pitches that have been tracked by the PITCHf/x system between 2017 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (92mph), Fourseam Fastball (92mph) and Slider (85mph), also mixing in a Cutter (89mph) and Curve (76mph). He also rarely throws a Change (87mph).
In 2025, compared to other RHP:
Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers and has some natural sinking action. Their fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has less armside movement than typical and has essentially average velo. Their slider is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, results in more flyballs compared to other pitchers' cutters and has strong cutting action. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, has sweeping glove-side movement, results in more flyballs compared to other pitchers' curves, has a sharp downward bite and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 4 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
