CHICAGO -- A 22-year-old fan has been banned indefinitely from all MLB ballparks after yelling something about Arizona Diamondbacks second baseman Ketel Marte's late mother during Tuesday night's game against the Chicago White Sox, according to a source. Marte's mother, Elpidia Valdez, died in a car accident in the Dominican Republic in 2017. "We commend the White Sox for taking immediate action in removing the fan," said MLB in a statement. It's not the first incident this season of a fan yelling something inappropriate at a player on the field. The White Sox avoided being swept in the series finale Wednesday with a 7-3 victory.
