Detroit Tigers
Although they have not thrown an MLB pitch in 2024, Luis Castillo threw 90 pitches that were tracked by the PITCHf/x system in 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (94mph) and Slider (84mph), also mixing in a Change (88mph). He also rarely threw a Sinker (93mph).
In 2022, compared to other RHP:
Their fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, generates fewer whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their slider has exceptional depth and generates more whiffs/swing compared to other pitchers' sliders. Their change (take this with a grain of salt because they've only thrown 13 of them in 2022) is thrown extremely hard, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their sinker (take this with a grain of salt because they've only thrown 3 of them in 2022) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has some natural sinking action.
