Arizona Diamondbacks
Shelby Miller has thrown 15,925 pitches that have been tracked by the PITCHf/x system between 2012 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (95mph) and Splitter (87mph), also mixing in a Slider (83mph). He also rarely throws a Cutter (89mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, results in somewhat more flyballs compared to other pitchers' fourseamers, has slight armside run and has slightly above average velo. Their splitter has an obvious armside fade, is much firmer than usual, results in many more groundballs compared to other pitchers' splitters and has some natural sink to it. Their slider sweeps across the zone and has some two-plane movement. Their cutter (take this with a grain of salt because they've only thrown 2 of them in 2025) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has strong cutting action.
