'Racism is as American as baseball' banner unfurled over Fenway Park's Green Monster

"Racism is as American as baseball," the sign said.

A Red Sox spokesman said security removed the four fans who held the sign, according to The Associated Press. One fan reportedly said the group drew inspiration from Black Lives Matter.

The Red Sox issued the following statement:

“During the 4th inning of tonight’s game, four fans unfurled a banner over the left field wall in violation of the club’s policy prohibiting signs of any kind to be hung or affixed to the ballpark. The individuals involved were escorted out of Fenway Park.”
