Non-MLB
Although they have not thrown an MLB pitch in 2024, Roberto Osuna threw 5,170 pitches that were tracked by the PITCHf/x system between 2015 and 2020, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2020, they relied primarily on their Fourseam Fastball (94mph) and Cutter (90mph), also mixing in a Change (81mph), Sinker (94mph) and Slider (88mph).
In 2020, compared to other RHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. Their cutter generates a high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has good "rise", has slightly above average velo and has strong cutting action. Their change (take this with a grain of salt because they've only thrown 11 of them in 2020) generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has slightly below average velo. Their sinker (take this with a grain of salt because they've only thrown 7 of them in 2020) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run, has well above average velo and has little sinking action compared to a true sinker. Their slider (take this with a grain of salt because they've only thrown 7 of them in 2020) generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut and is much harder than usual.
