I'm benching him. #1 WHIP, ERA finally under 4, hell no.
Believe it or not, Contreras didn't face Boston at home last year in a start, period. There's just something about him and Boston for some reason.
The hot/cold thing really might have some effect, because if you look at his splits, he's a better player in the daytime (when it's usually warmer). It might be because Cuba's hotter, so he's more used to warm weather. I may be reaching here with the weather stuff, but I'm still going to bench him.
