Yeah, there's almost no such thing as a pitcher able to pitch back-to-back games in the playoffs. For whatever reason the fatigue metrics just don't tolerate pitchers being used in back-to-back games in the playoffs much. I can't figure this one out either.
Also, Moore's IP/G is garbage and you can pretty much guarantee he's going to break down in the 5th inning if you try to start him. But that's not your issue -- it's ultimately just small sample size, on that one. Every pitcher is going to have bad games, and Moore isn't exactly Addie Joss out there.
