Seattle Mariners
Matt Brash has thrown 3,434 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2025, they have relied primarily on their Slider (86mph) and Sinker (97mph), also mixing in a Change (90mph). He also rarely throws a Fourseam Fastball (96mph) and Curve (83mph).
In 2025, compared to other RHP:
Their slider sweeps across the zone, has exceptional depth and results in somewhat more groundballs compared to other pitchers' sliders. Their sinker is basically never swung at and missed compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, has an obvious tail, results in many more groundballs compared to other pitchers' sinkers and has some natural sinking action. Their change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups and dives down out of the zone. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has well above average velo. Their curve (take this with a grain of salt because they've only thrown 3 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' curves, is much harder than usual, results in more flyballs compared to other pitchers' curves and has slight glove-side movement.
