The fan who yelled at Ketel Marte about his late mother was a 22-year-old Chicago White Sox fan. This fan shouted something derogatory and deeply personal about Marte's mother, who passed away in a car accident in 2017. The incident happened during a game against the White Sox, and the fan was immediately ejected and then banned indefinitely from all MLB ballparks. Diamondbacks manager Torey Lovullo confronted the fan during the game to protect Marte. The exact words the fan yelled were reported by Marte as something along the lines of "Last night I sent a message to your mother," which brought Marte to tears on the field. The White Sox and MLB took swift action to remove and ban the fan, condemning such behavior as unacceptable in baseball and society.
