Oakland Athletics
Although they have not thrown an MLB pitch in 2024, Duane Below threw 1,226 pitches that were tracked by the PITCHf/x system between 2011 and 2013, all of them occuring in the MLB Regular Season. In 2013, they relied primarily on their Fourseam Fastball (91mph) and Slider (86mph), also mixing in a Change (85mph) and Curve (80mph).
In 2013, compared to other LHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo, has slightly less natural movement than typical and has some added backspin. Their slider (take this with a grain of salt because they've only thrown 16 of them in 2013) is basically never swung at and missed compared to other pitchers' sliders and is much harder than usual. Their change (take this with a grain of salt because they've only thrown 6 of them in 2013) is an extreme flyball pitch compared to other pitchers' changeups, has a lot of backspin and is slightly firmer than usual. Their curve (take this with a grain of salt because they've only thrown 6 of them in 2013) is an extreme flyball pitch compared to other pitchers' curves, has primarily 12-6 movement, generates fewer whiffs/swing compared to other pitchers' curves and is much harder than usual.
