The question I have now is whether he actually pitched good last year.
A 4.34 ERA for a guy who pitches in a pitcher's park didn't use to be considered good at all.
He had a 3.0 fWAR because of a 3.57 FIP, I guess. But I question whether fWAR for a pitcher is all that reliable. His bWAR was 0.8, which sucks for that number of innings.
