Hadn't thought about the fact that it is now October. Phillies finish September 11-14, their second losing month (they were 11-11 in April and 11-18 in May).
4-2 in October should do it. 5-1 obviously clinches it. 3-3 means that they need two Brewers losses which I think is reasonable. But they really blew their best chance to make the last series largely moot, and the weather may not help in that regard either.
