Los Angeles Dodgers
Clayton Kershaw has thrown 34,040 pitches that have been tracked by the PITCHf/x system between 2007 and 2018, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2018, he has relied primarily on his Slider (89mph) and Fourseam Fastball (91mph), also mixing in a Curve (73mph). He also rarely throws a Change (85mph) and Sinker (91mph).
Basic description of 2018 pitches compared to other LHP:
His slider is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has much less depth than expected and generates fewer whiffs/swing compared to other pitchers' sliders. His fourseam fastball is straight as an arrow, has good "rising" action and has essentially average velo. His curve has an exceptional bite, 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 10 of them in 2018) 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, is much firmer than usual and has an extreme amount of backspin. His sinker (take this with a grain of salt because he's only thrown 6 of them in 2018) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has virtually no sinking action reminiscent of a true sinker.
