Francisco Pérez has thrown 1,480 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 (83mph), also mixing in a Fourseam Fastball (92mph), Sinker (92mph) and Change (87mph). He also rarely throws a Curve (76mph).
In 2024, compared to other LHP:
Their slider has some two-plane movement. Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical and has essentially average velo. Their sinker is basically never swung at and missed compared to other pitchers' sinkers, has surprisingly little armside run, results in somewhat more flyballs compared to other pitchers' sinkers and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 15 of them in 2024) is thrown extremely hard, is an extreme flyball pitch compared to other pitchers' changeups and has slight cut action. Their curve (take this with a grain of salt because they've only thrown 7 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has a sharp downward bite.
