Let's be clear though. You DO need a fourth starter even for a five game series. (Unless you want #1 to pitch game four on short rest, which I don't, because you don't want to stress #1 so early in the playoffs. A pitcher can be 100% effective on short rest; the effect of the short rest comes the next start.) But the point is, you don't really need to win game 4, if #1, #2, and #3 are doing their job (or for that matter just #1 and #2).
