Seattle Mariners
Luis F. Castillo has thrown 624 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2025, they have relied primarily on their Fourseam Fastball (93mph), Slider (81mph) and Sinker (93mph), also mixing in a Change (87mph).
In 2025, compared to other RHP:
Their fourseam fastball has heavy sinking action, results in more flyballs compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their slider sweeps across the zone, has below average velo, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their sinker has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, has an obvious tail and generates fewer whiffs/swing compared to other pitchers' sinkers. Their change dives down out of the zone, is much firmer than usual and has slight armside fade.
