Non-MLB
Although they have not thrown an MLB pitch in 2024, César Vargas threw 685 pitches that were tracked by the PITCHf/x system between 2016 and 2023, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2023, they relied primarily on their Fourseam Fastball (94mph) and Slider (83mph).
In 2023, compared to other RHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has much less armside movement than typical, has some natural sinking action and has slightly above average velo. Their slider (take this with a grain of salt because they've only thrown 10 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' sliders, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders.
