Los Angeles Dodgers
Clayton Kershaw has thrown 22,383 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 (95mph) and Slider (87mph), also mixing in a Curve (75mph).
Basic description of 2015 pitches compared to other LHP:
His fourseam fastball is straight as an arrow, is blazing fast, generates fewer whiffs/swing compared to other pitchers' fourseamers and has good "rising" action. His slider (take this with a grain of salt because he's only thrown 17 of them in 2015) is thrown extremely hard, is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut and has less than expected depth. His curve (take this with a grain of salt because he's only thrown 8 of them in 2015) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has a sharp downward bite and has primarily 12-6 movement.
