How about THIS playoff scenario?
From todays NY Times online:
Assuming there is no makeup game Monday, if the Mets, Brewers and Phillies finish with the same record after 162 games, the Mets and the Phillies will play a one-game playoff Monday in Philadelphia to determine the N.L. East champion. The loser of that game would host the Brewers on Tuesday to decide the wild-card winner.
So who would the Cubs get and when would they play? Still on Wednesday?
