A fan who heckled Arizona Diamondbacks second baseman Ketel Marte during a game against the Chicago White Sox at Rate Field on Tuesday night has been banned indefinitely from all major league stadiums, a person with direct knowledge of the decision told The Associated Press.

Marte was seen in tears on the field after the spectator yelled a derogatory comment about Marte’s late mother during a seventh-inning at-bat in Arizona’s 4-1 win over Chicago.

According to a White Sox spokesperson, the security staff at the ballpark relayed that the 22-year-old fan was “very apologetic and remorseful after the fact, and admitted to being very inappropriate and stupid with his comments.” Another person confirmed to the AP that Major League Baseball had banned the fan from all big league stadiums. That person spoke on condition of anonymity because the punishment wasn’t announced by the league.
