Seattle Mariners
Luis Castillo has thrown 24,964 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 (85mph), 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 heavy sinking action, results in more flyballs compared to other pitchers' fourseamers, has slight armside run and has slightly above average velo. Their slider has primarily 12-6 movement, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. Their sinker has heavy sinking action, has an obvious tail and has well above average velo. Their change has an obvious armside fade, dives down out of the zone and is much 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.
