As of the time of this post, Gio Gonzalez's WAR is 0.01 ahead of Max Scherzer. It's a pretty small difference, but when I look at the more traditional stats, it's really hard to see why they should even be close.
Gonzalez: 2.50 ERA, 1.14 WHIP, 163 K's in 179 IP
Scherzer: 2.32 ERA, 0.87 WHIP, 239 K's in 178 IP
I always thought that sabermetrics-oriented stats tended to favor pitchers who struck out more batters. Scherzer has way more strikeouts and far fewer baserunners allowed (as indicated by the WHIP). Can someone explain why their WARs are so similar despite this? In my view, there's a pretty huge difference in WHIP and K's. Also, there's a really big difference in their FIP values -- Gonzalez is at 3.89 while Scherzer is at 2.96. Why don't these differences show up in the WAR for each pitcher?
