Good news for the Cubs as they watch their ace, Jake Arrieta, finish off a complete game. He has been just as good with four days’ rest throughout his career as he has with five days off between starts — and far better in 2015 after four days off than after five. Bad news for the Cubs: Arrieta would need to sit out until Game 3 of the National League Division Series against the Cardinals to get four days’ rest. Last year’s NL wild-card-winning ace, Madison Bumgarner, also didn’t pitch again until Game 3 of the division series, but his rotation mates stepped up and helped him lift the Giants to the NLCS.
