BOSTON — A Boston Red Sox fan was ejected from the team’s home field and banned for life on Tuesday for using a racial slur.

The incident took place before Boston’s game with Baltimore at Fenway Park, just one night after Orioles outfielder Adam Jones said he was racially abused and had peanuts thrown at him by the home crowd.

Red Sox fan Calvin Hennick, who has a mixed-race family, said he took his son to his first baseball game on Tuesday night.

Hennick wrote on Twitter that he was shocked when a fellow member of the Red Sox Nation made a racial slur in reference to a Kenyan woman who sang the pre-game national anthem.

Thinking he’d misheard, Hennick asked the man to repeat himself. And sure enough, the racist said he stood by his racist comments.

Hennick reported the man to security, who knocked the man out of the park and told him never to come back.

Red Sox president Sam Kennedy later said he was saddened by the incident and believed this was the first time the team had banned a fan for life, according to the Sox official website.

In a statement, the Red Sox said racism would not be tolerated at Fenway Park and the matter had been referred to the police.
