Diamondbacks' second baseman Ketel Marte's mom died tragically. Elpidia Valdez passed away in a 2017 car accident in the Dominican Republic, according to My Stateline. Thus, it's not surprising that Marte is still emotional about the topic.

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.

The Chicago White Sox have indefinitely banned a fan from their home games after he brought Arizona Diamondbacks' Ketel Marte to tears after heckling him about his late mother.
