Schedule for the Brewers the rest of the way is so woof. At least the Pirates have been playing well of late. Cubs need a Brewers cool down somewhere.
Also, if the Cubs and Reds end up tied in the standings the Reds have the tie breaker. Have to keep winning games.
The odds are the Cubs play the Phillies or Brewers if they make the playoffs. The best option is to chase down the Brewers and play the 6th seed which will probably be the Dbacks, Marlins, Reds or Giants.
