Ryne Harper has thrown 440 pitches that have been tracked by the PITCHf/x system between 2014 and 2019, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2019, he has relied primarily on his Slider (76mph) and Fourseam Fastball (90mph), also mixing in a Curve (69mph). He also rarely throws a Change (76mph).
Basic description of 2019 pitches compared to other RHP:
His slider comes in below hitting speed, sweeps across the zone, has exceptional depth and results in more flyballs compared to other pitchers' sliders. His fourseam fastball has heavy sinking action, is straight as an arrow and has below average velo. His curve comes in below hitting speed, generates a very high amount of groundballs compared to other pitchers' curves, has a sharp downward bite and has slight glove-side movement. His change (take this with a grain of salt because he's only thrown 5 of them in 2019) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, dives down out of the zone and results in more flyballs compared to other pitchers' changeups.
