One week ago, rock legends AC/DC played a concert at Chicago's Wrigley Field. The stage was set up in the outfield grass and thousands of fans gathered along the infield dirt to watch the show. Six days later, the Cubs committed three errors but still beat the Brewers 9-5. After the game, Cubs manager Joe Maddon told the Chicago Tribune that AC/DC and not his players were the cause for the miscues.

“Since the AC/DC concert, we’ve had a little bit of trouble. I don’t know if they were out there taking ground balls before the game, or if they had 9-inch heels or spikes. They totally messed up the infield, and it has nothing to do with the groundskeepers. I’ve seen a bad hop at third, and a bad hop at second. I didn’t see one bad hop all year.”

The timing could not be any worse since the Cubs are fighting for a playoff spot with just twp weeks left in the season. One Tribune columnist even called for an end to concerts at Wrigley Field during baseball season.
