Although he has not thrown an MLB pitch in 2020, Montana DuRapau threw 462 pitches that were tracked by the PITCHf/x system between 2016 and 2019, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2019, he relied primarily on his Fourseam Fastball (92mph) and Slider (87mph), also mixing in a Curve (81mph). He also rarely threw a Change (85mph).
Basic description of 2019 pitches compared to other RHP:
His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. His slider is an extreme flyball pitch compared to other pitchers' sliders, generates more whiffs/swing compared to other pitchers' sliders and has short glove-side cut. His curve is basically never swung at and missed compared to other pitchers' curves and is slightly harder than usual. His change (take this with a grain of salt because he's only thrown 11 of them in 2019) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has a lot of backspin and is slightly firmer than usual.
