Is Max Scherzer the World’s Best Pitcher?

In the 2015 Bill James Handbook, Bill James introduced his new formula to determine the World’s Best Pitcher at any given time. The system is based on Game Scores and weighs positive and negative recent performances more heavily than older performances. As of the publication of the Handbook, Clayton Kershaw was the No. 1 pitcher in baseball by a substantial margin, and even in the Stat of the Week update from November that reflected Madison Bumgarner’s dominant playoff performance, Kershaw was still well clear of the field.

So far in 2015, Kershaw has been a little less dominant than his usual self. That combined with some excellent pitching performances from some of his peers, one in particular, has radically closed the gap:

Specifically, Max Scherzer has flown up the rankings this year thanks to his 1.79 ERA and his league-leading 9.3 strikeouts per walk. Following his no-hitter, Scherzer has pulled close to even with Kershaw. Kershaw is still No. 1, but that title is at jeopardy for the first time since June 1, 2014, when Scherzer briefly held the title. Kershaw has been so dominant for so long, that the last starter other than Scherzer to have the title over him is Justin Verlander back in early 2013! A change could happen as soon as Thursday when Scherzer and the Nationals take on the Braves.
