Non-MLB
Although they have not thrown an MLB pitch in 2024, Jumbo Díaz threw 2,974 pitches that were tracked by the PITCHf/x system between 2014 and 2023, including pitches thrown in the MLB Regular Season, The World Baseball Classic, Spring Training and Fall/Winter Ball. In 2023, they relied primarily on their Slider (83mph) and Fourseam Fastball (90mph), also mixing in a Change (85mph). He also rarely threw a Sinker (90mph).
In 2023, compared to other RHP:
Their slider (take this with a grain of salt because they've only thrown 13 of them in 2023) generates more whiffs/swing compared to other pitchers' sliders, results in many more groundballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 12 of them in 2023) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has less armside movement than typical and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 3 of them in 2023) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has slight cut action. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2023) 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 little sinking action compared to a true sinker and has slightly below average velo.
