Although he has not thrown an MLB pitch in 2019, Matt Stites threw 928 pitches that were tracked by the PITCHf/x system between 2012 and 2016, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2016, he relied primarily on his Fourseam Fastball (93mph), also mixing in a Slider (86mph).
Basic description of 2016 pitches compared to other RHP:
His fourseam fastball (take this with a grain of salt because he's only thrown 6 of them in 2016) 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 and has some added backspin. His slider (take this with a grain of salt because he's only thrown 1 of them in 2016) is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has much less depth than expected.
