Clayton Kershaw has thrown 25,931 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 Fourseam Fastball (94mph) and Slider (89mph), also mixing in a Curve (74mph). He also rarely throws a Change (88mph).
Basic description of 2015 pitches compared to other LHP:
His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is straight as an arrow, generates more whiffs/swing compared to other pitchers' fourseamers, has good "rising" action and has well above average velo. His slider is thrown extremely hard, generates more whiffs/swing compared to other pitchers' sliders, results in many more groundballs compared to other pitchers' sliders and has less than expected depth. His curve has an exceptional bite, generates more whiffs/swing compared to other pitchers' curves, has primarily 12-6 movement and has slightly below average velo. His change (take this with a grain of salt because he's only thrown 15 of them in 2015) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and has an extreme amount of backspin.
