Chapman served a 29-game suspension to begin the season under Major League Baseball’s new domestic violence policy. His girlfriend told police Chapman had pushed and choked her on Oct. 30. Chapman said there was an argument but he was pushed down by his girlfriend’s brother, then got a handgun and fired eight shots into a wall and window while locked in his garage.

Prosecutors declined to file charges, citing conflicting accounts.

Cubs President Crane Kenney apologized, saying the music selection showed “a lack of judgment and sensitivity to an important issue.” He said the Cubs will implement stronger controls to review and approve music before it is played.
