Non-MLB
Although they have not thrown an MLB pitch in 2024, David Huff threw 6,827 pitches that were tracked by the PITCHf/x system between 2009 and 2016, including pitches thrown in the MLB Regular Season and Spring Training. In 2016, they relied primarily on their Fourseam Fastball (91mph) and Change (82mph), also mixing in a Cutter (89mph) and Slider (80mph).
In 2016, compared to other LHP:
Their fourseam fastball generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their change is basically never swung at and missed compared to other pitchers' changeups, has slight cut action, has a lot of backspin and results in somewhat more groundballs compared to other pitchers' changeups. Their cutter (take this with a grain of salt because they've only thrown 14 of them in 2016) is an extreme flyball pitch compared to other pitchers' cutters, generates fewer whiffs/swing compared to other pitchers' cutters, has surprisingly little cutting action, has well above average velo and has some natural sink. Their slider (take this with a grain of salt because they've only thrown 11 of them in 2016) generates an extremely high number of swings & misses compared to other pitchers' sliders, has exceptional depth, results in more flyballs compared to other pitchers' sliders and has below average velo.
