Thank you for that information MrCleo. I just looked into that myself but you were a little faster on the draw. They split a 4-game set with the Marlins as well and that's really the only other time they failed to win a home series.
So out of 18 series at home, they have gone 14-3-1. One of the two series they dropped to the Brewers was the opening series at home this season back in March and running into April. Ironically it was Ryan Dempster, tonight's pitcher, on the mound in each of the Cubs two victories when they dropped those pair of three-game sets against Milwaukee at home.
