Tyler Duffey has thrown 9,103 pitches that have been tracked by the PITCHf/x system between 2015 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (90mph), also mixing in a Change (81mph), Curve (80mph), Slider (80mph) and Sinker (91mph). He also rarely throws a Slow Curve (72mph).
In 2024, compared to other RHP:
Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has slightly below average velo. Their change generates an extremely high number of swings & misses compared to other pitchers' changeups, results in many more groundballs compared to other pitchers' changeups, has slight armside fade, has slightly below average velo and has some natural sink to it. Their curve generates fewer whiffs/swing compared to other pitchers' curves, has a sharp downward bite and is slightly harder than usual. Their slider comes in below hitting speed, sweeps across the zone, generates a high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 18 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action and is an extreme flyball pitch compared to other pitchers' sinkers. Their slow curve (take this with a grain of salt because they've only thrown 1 of them in 2024) is a real yakker that's separated from their other curveball due to its big drop and slow speed.
