Non-MLB
Although they have not thrown an MLB pitch in 2024, Juan Pablo Perez threw 902 pitches that were tracked by the PITCHf/x system between 2007 and 2013, including pitches thrown in the MLB Regular Season and Spring Training. In 2013, they relied primarily on their Fourseam Fastball (94mph) and Slider (83mph). He also rarely threw a Change (88mph).
In 2013, compared to other LHP:
Their fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has well above average velo and has slight armside run. Their slider generates more whiffs/swing compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their change (take this with a grain of salt because they've only thrown 7 of them in 2013) is thrown extremely hard and results in more flyballs compared to other pitchers' changeups.
