Seattle Mariners

Pitch Repertoire At-A-Glance

Gregory Santos has thrown 1,792 pitches that have been tracked by the PITCHf/x system between 2021 and 2024, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2024, they have relied primarily on their Slider (90mph) and Sinker (99mph).


In 2024, compared to other RHP:
Their slider is thrown extremely hard, generates fewer whiffs/swing compared to other pitchers' sliders and results in many more groundballs compared to other pitchers' sliders. Their sinker is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical and has some natural sinking action.
