Joe Maddon complained about conditions in the infield at Wrigley Field after a recent concert.
"Since the AC/DC concert we've had a little bit of trouble," Maddon said Monday night. "I don't know if they [the band] were out there taking ground balls in 9-inch heels."
The subject came up after an error by Starlin Castro, which Maddon blamed on a bad hop.
"They totally messed up our infield," Maddon said. "I've seen a bad hop at third, a bad hop at second. Prior to that I've not seen one bad hop all year."
It's unclear how much the infield was affected by the concert held last week but the Cubs completely ripped up the outfield grass and replaced it with new sod. There have been more complaints about the new outfield grass.
"Infield is OK," Castro said. "The grass on the outfield is bad. … It's not even. Some long, some short. It's not what it used to be."
