Seattle Mariners
Luis Castillo has thrown 18,360 pitches that have been tracked by the PITCHf/x system between 2017 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (95mph) and Slider (85mph), also mixing in a Sinker (95mph) and Change (88mph).
In 2024, compared to other RHP:
Their fourseam fastball generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action, has well above average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slight armside run. Their slider (take this with a grain of salt because they've only thrown 12 of them in 2024) has exceptional depth, is an extreme flyball pitch compared to other pitchers' sliders and has primarily 12-6 movement. Their sinker (take this with a grain of salt because they've only thrown 17 of them in 2024) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, has an obvious tail, is blazing fast and results in somewhat more flyballs compared to other pitchers' sinkers. Their change (take this with a grain of salt because they've only thrown 14 of them in 2024) has an obvious armside fade, dives down out of the zone, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
