over a hundred years of postseason glory aside, the Cubs still have a 40+ victory advantage in the all-time regular season series matchup with the Cards. Granted, this years Cubs stink pretty bad (although they did improve over the weekend by trading Marlon Byrd).
Other than Volstad in the 3rd game, the Cubs have some decent pitching matchups with Garza going up against Garcia and Samardzija with Wainwright in the first two games. Garcia has been pretty solid this year but Wainwright has been struggling.
Who knows, it's baseball. Stranger things have happened.
