Kansas City Royals
Although they have not thrown an MLB pitch in 2024, Tyler Duffey threw 8,947 pitches that were tracked by the PITCHf/x system between 2015 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Fourseam Fastball (92mph), Curve (81mph) and Slider (81mph), also mixing in a Sinker (92mph). He also rarely threw a Change (83mph) and Slow Curve (71mph).
In 2023, compared to other RHP:
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, has essentially average velo and has slightly less natural movement than typical. Their curve generates a very high amount of groundballs compared to other pitchers' curves, has a sharp downward bite and is slightly harder than usual. Their slider sweeps across the zone, results in more flyballs compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their sinker generates a high number of swings & misses compared to other pitchers' sinkers, results in somewhat more flyballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their change generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their slow curve (take this with a grain of salt because they've only thrown 5 of them in 2023) is a real yakker that's separated from their other curveball due to its big drop and slow speed.
