Over the last 365 days, Clayton Kershaw has been baseball’s best pitcher. That isn’t a particularly enlightening sentence given that he’s almost certainly been the league’s best pitcher over the last several years, as well. At this point, the question isn’t really if Kershaw is the best pitcher, but rather if he is the best overall player, Mike Trout included. Kershaw has truly been that phenomenal.
To put some numbers behind it, consider: since May 26, 2015, Kershaw has thrown 253.1 regular-season innings (34 starts) and produced a 39 ERA- and 42 FIP-, thanks in part to a 34.8 K% and 3.3 BB%. By our WAR model, that’s equivalent to an 11-WAR season. It’s closer to 12 WAR if you use runs allowed as the primary input instead of FIP.
We all have our own favorite Kershaw fun fact, but here’s one that’s been bubbling to the surface lately. Full disclosure: I’ve been partially responsible for said bubbling.

Some context: since 1961, there have been just a handful of qualified starters to record less than a 40 ERA- in a single season and the only two qualified seasons under 40 FIP- belong to Pedro in 1999 and Kershaw in 2016. Those Pedro years are often considered the modern gold standard of starting-pitcher dominance. He was 60% better than league average for two full seasons.
