Seattle Mariners
Luis Castillo has thrown 24,398 pitches that have been tracked by the PITCHf/x system between 2017 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (95mph) and Slider (84mph), also mixing in a Sinker (95mph) and Change (87mph). He also rarely throws a Cutter (91mph).
In 2026, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, results in somewhat more flyballs compared to other pitchers' fourseamers, has slight armside run and has slightly above average velo. Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, has an obvious tail, has well above average velo and results in somewhat more flyballs compared to other pitchers' sinkers. Their change has an obvious armside fade, dives down out of the zone, generates fewer whiffs/swing compared to other pitchers' changeups and is slightly firmer than usual. Their cutter (take this with a grain of salt because they've only thrown 5 of them in 2026) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action, has well above average velo and has some natural sink.
