Although he has not thrown an MLB pitch in 2016, Collin McHugh threw 7,084 pitches that were tracked by the PITCHf/x system between 2011 and 2015, including pitches thrown in the MLB Regular Season, the MLB Postseason and Fall/Winter Ball. In 2015, he relied primarily on his Cutter (88mph), Fourseam Fastball (91mph) and Curve (74mph). He also rarely threw a Change (83mph) and Slider (78mph).
Basic description of 2015 pitches compared to other RHP:
His cutter has some natural sink and has strong cutting action. His fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers and has slightly below average velo. His curve has below average velo, has a sharp downward bite and has slight glove-side movement. His change is a prototypical pitch with few remarkable qualities. His slider (take this with a grain of salt because he's only thrown 2 of them in 2015) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement.
