Although he has not thrown an MLB pitch in 2015, Scott Feldman threw 17,557 pitches that were tracked by the PITCHf/x system between 2007 and 2014, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2014, he relied primarily on his Cutter (88mph), Sinker (90mph) and Curve (76mph). He also rarely threw a Change (85mph), Fourseam Fastball (89mph) and Slow Curve (68mph).
Basic description of 2014 pitches compared to other RHP:
His cutter is basically never swung at and missed compared to other pitchers' cutters and has strong cutting action. His sinker has less armside run than typical and has slightly below average velo. His curve results in somewhat more flyballs compared to other pitchers' curves, has slight glove-side movement and has slightly below average velo. His change generates fewer whiffs/swing compared to other pitchers' changeups, results in somewhat more groundballs compared to other pitchers' changeups and has slight armside fade. His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and has below average velo. His slow curve (take this with a grain of salt because he's only thrown 3 of them in 2014) is a real yakker that's separated from his other curveball due to its big drop and slow speed.
