Drey Jameson has thrown 3,702 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, compared to other RHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair and has some natural sinking action. Their slider results in more flyballs compared to other pitchers' sliders, is much harder than usual and has some two-plane movement. Their change is thrown extremely hard, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their sinker is blazing fast, results in somewhat more groundballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their cutter (take this with a grain of salt because they've only thrown 1 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 and has surprisingly little cutting action.
