A man at a baseball game who ridiculed the dead mother of the Arizona Diamondbacks' Ketel Marte has been banned by the White Sox and Major League Baseball indefinitely, the league confirmed Wednesday.

The fan who taunted Arizona Diamondbacks second baseman Ketel Marte about his deceased mother on Tuesday night at Rate Field has been banned by the Chicago White Sox, sources told Jesse Rogers of ESPN. Additionally, the fan has been banned indefinitely from all MLB ballparks.

Once the team found out what had happened, it worked with MLB to identify and punish the fan in question. Though the White Sox didn't release the fan's name, they said that the 22-year-old would be banned from all MLB ballparks indefinitely.
