From the Chicago Tribune’s Paul Sullivan :

The Cubs are preparing to discipline the Wrigley Field DJ who played an inappropriate song after Aroldis Chapman’s appearance during Sunday night’s game.

The ’90s song, “Smack My Bitch Up” by the English band the Prodigy, came on the PA system after Chapman left the mound in the top of the ninth inning.

Chapman served a 30-game suspension with the Yankees this year after an alleged domestic violence incident in which Chapman was accused of choking his girlfriend and firing eight bullets in his garage. Chapman was not arrested and no charges were filed.

A source said the DJ would be disciplined for what the team said was accidental timing, and a statement would be released later today.
