Tyler Duffey

Chicago Cubs

Pitch Repertoire At-A-Glance

Although they have not thrown an MLB pitch in 2023, Tyler Duffey threw 8,166 pitches that were tracked by the PITCHf/x system between 2015 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (92mph) and Curve (82mph), also mixing in a Sinker (92mph), Slider (84mph) and Change (78mph). He also rarely threw a Slow Curve (73mph).


In 2022, compared to other RHP:
His fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and has essentially average velo. His curve is much harder than usual, results in many more groundballs compared to other pitchers' curves, has a sharp downward bite and has primarily 12-6 movement. His sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and has some natural sinking action. His slider sweeps across the zone, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. His change comes in below hitting speed and results in more flyballs compared to other pitchers' changeups. His slow curve is a real yakker that's separated from his other curveball due to its big drop and slow speed.
