Mason Miller has thrown 1,438 pitches that have been tracked by the PITCHf/x system between 2022 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (101mph) and Slider (88mph). He also rarely throws a Change (92mph) and Sinker (98mph).
In 2024, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider has exceptional depth, generates a high number of swings & misses compared to other pitchers' sliders, has short glove-side cut and is much harder than usual. Their change (take this with a grain of salt because they've only thrown 7 of them in 2024) is thrown extremely hard, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their sinker (take this with a grain of salt because they've only thrown 2 of them in 2024) is basically never swung at and missed compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has some natural sinking action.
