Arizona Diamondbacks
Although they have not thrown an MLB pitch in 2024, Brad Ziegler threw 10,424 pitches that were tracked by the PITCHf/x system between 2008 and 2018, including pitches thrown in the MLB Regular Season and Spring Training. In 2018, they relied primarily on their Sinker (85mph), also mixing in a Slider (74mph) and Change (77mph).
In 2018, compared to other RHP:
Their sinker is so slow that it is substantially gravitational, has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and has less armside run than typical. Their slider comes in below hitting speed, sweeps across the zone, has much less depth than expected, generates more whiffs/swing compared to other pitchers' sliders and results in many more groundballs compared to other pitchers' sliders. Their change comes in below hitting speed, has surprising cut action, dives down out of the zone and generates a high number of swings & misses compared to other pitchers' changeups.
