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.

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.

Just a day after a fan at Rate Field taunted Arizona Diamondbacks second baseman Ketel Marte about his mother, who died in a 2017 car accident, the Chicago White Sox and their fans showed support for the two-time All-Star during his first at-bat of Wednesday's game.
