Clayton Kershaw has been the best pitcher in baseball for at least the last five seasons. He will be 28 in a couple weeks and could theoretically just be entering his prime, which has to be a terrifying proposition for hitters elsewhere.
2015 recap
Kershaw had a strange 2015 season. Coming off an MVP 2014 campaign, Kershaw struggled (by Kershaw standards) out of the gate. In his first nine starts, Kershaw went 2-3 and allowed 56 hits in 58 1/3 innings. He allowed six home runs in his first nine starts, after allowing nine total homers in 2014.
