Non-MLB
Although they have not thrown an MLB pitch in 2024, Ervin Santana threw 33,535 pitches that were tracked by the PITCHf/x system between 2007 and 2021, including pitches thrown in the MLB Regular Season and Spring Training. In 2021, they relied primarily on their Slider (84mph) and Fourseam Fastball (93mph). He also rarely threw a Change (87mph) and Sinker (93mph).
In 2021, compared to other RHP:
Their slider results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball has less armside movement than typical, has some natural sinking action and has essentially average velo. Their change is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual, has slight cut action and has a lot of backspin. Their sinker (take this with a grain of salt because they've only thrown 4 of them in 2021) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical and has slightly above average velo.
