Arizona Diamondbacks
Although they have not thrown an MLB pitch in 2024, Steve Hathaway threw 268 pitches that were tracked by the PITCHf/x system in 2016, including pitches thrown in the MLB Regular Season and Spring Training. In 2016, they relied primarily on their Fourseam Fastball (93mph) and Curve (77mph), also mixing in a Change (85mph).
In 2016, compared to other LHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has some natural sinking action, has slight armside run and has slightly above average velo. Their curve results in somewhat more groundballs compared to other pitchers' curves and has slight glove-side movement. Their change (take this with a grain of salt because they've only thrown 16 of them in 2016) is an extreme flyball pitch compared to other pitchers' changeups and is much firmer than usual.
