Scott Feldman has thrown 18,456 pitches that have been tracked by the PITCHf/x system between 2007 and 2015, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2015, he has relied primarily on his Cutter (89mph), Sinker (91mph) and Curve (75mph). He also rarely throws a Change (85mph) and Fourseam Fastball (90mph).
Basic description of 2015 pitches compared to other RHP:
His cutter is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters, generates fewer whiffs/swing compared to other pitchers' cutters and has strong cutting action. His sinker has less armside run than typical and results in somewhat more groundballs compared to other pitchers' sinkers. His curve has slight glove-side movement and has slightly below average velo. His change generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has slight armside fade. His fourseam fastball (take this with a grain of salt because he's only thrown 18 of them in 2015) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has slightly below average velo.
