Washington Nationals
Although they have not thrown an MLB pitch in 2023, Francisco Perez threw 327 pitches that were tracked by the PITCHf/x system between 2021 and 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (93mph) and Slider (83mph). He also rarely threw a Change (85mph) and Curve (76mph).
In 2022, compared to other LHP:
His fourseam fastball has less armside movement than typical and has slightly above average velo. His slider results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. His change (take this with a grain of salt because he's only thrown 4 of them in 2022) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups, has a lot of backspin and is slightly firmer than usual. His curve (take this with a grain of salt because he's only thrown 2 of them in 2022) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has a sharp downward bite.
