Well, Stras's ERA is worse than most of his ERA estimators (FIP, xFIP, SIERA) so he might actually improve down the stretch, but Gio's obviously going to give up more than one home run this year and the rest of our starters are due for some negative regression as well. Coors Field is a prime candidate for some of that to happen. Other than its obvious traits, the park also depresses strikeout rates by over 10%. That might help our hitters more than it hurts our pitchers though Edit:
Nope, though it's close. Our pitching staff has a collective 22.5 K% and our hitters have a 21.9 K%, so the pitchers should be hurt more in absolute terms. 21.9 still sucks though, no wonder everyone we face seems to be having a career night.
