Gregory Santos

Chicago White Sox

Pitch Repertoire At-A-Glance

Although they have not thrown an MLB pitch in 2023, Gregory Santos threw 663 pitches that were tracked by the PITCHf/x system between 2021 and 2022, including pitches thrown in the MLB Regular Season and Fall/Winter Ball. In 2022, they relied primarily on their Slider (88mph) and Fourseam Fastball (99mph), also mixing in a Sinker (99mph). He also rarely threw a Change (92mph).


In 2022, compared to other RHP:
His slider is thrown extremely hard, generates more whiffs/swing compared to other pitchers' sliders and has some two-plane movement. His fourseam fastball has heavy sinking action, is thrown at a speed that's borderline unfair, has much less armside movement than typical and results in many more groundballs compared to other pitchers' fourseamers. His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, generates a very high amount of groundballs compared to other pitchers' sinkers and has surprisingly little armside run. His change (take this with a grain of salt because he's only thrown 2 of them in 2022) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
