I think the Cubs nice (and surprising) start of 12-7 got most fans optimism up. They weren't as good as that start indicated. Since then, they're 7-15 which is pretty bad. But not completely unexpected. I didn't like the sweep at Florida, exacerbated by the 1-run losses. But even worse was losing 3 of 4 to the Nats, especially after winning game one. A little bit of luck and that 7 game stretch could've been a little different. Otherwise, they really have played, series wise, not too unsuspectingly.
They came home and one the Florida series, lost the series to the Cards (not really surprising), lost the series to the Twins (one of the best starting rotations in baseball), and have now lost to the Astros in game 1. They'll probably lose this series and the next at Philly before coming home. And they have a decent shot of winning the home series against the Mets and Reds before facing TB.
I can see them going 7-7 in there next 14 to close out the month 3 games under. The schedule should even out a bit after that. Let's hope anyway.
