Last year he was certainly better than a middle of the rotation pitcher with a 4.8 fWAR and 3.12 xFIP... granted that's obviously been the outlier year. Still he's already at 0.9 fWAR this year... not sure if I'd freak out about the K-rate after just 59 innings although he's never been a huge strikeout pitcher. The thing that interests me more is that he never walks anyone.
