Cincinnati Reds
Although they have not thrown an MLB pitch in 2024, Zach Duke threw 15,212 pitches that were tracked by the PITCHf/x system between 2007 and 2019, including pitches thrown in the MLB Regular Season and Spring Training. In 2019, they relied primarily on their Sinker (89mph) and Slider (80mph), also mixing in a Curve (74mph) and Fourseam Fastball (88mph). He also rarely threw a Change (83mph).
In 2019, compared to other LHP:
Their sinker has heavy sinking action and has less armside run than typical. Their slider sweeps across the zone. Their curve has sweeping glove-side movement, results in somewhat more groundballs compared to other pitchers' curves and has slightly below average velo. Their fourseam fastball has heavy sinking action, is straight as an arrow, has below average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their change (take this with a grain of salt because they've only thrown 2 of them in 2019) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups.
