In the middle of the fourth inning of the Red Sox-Athletics game on Wednesday night, a sign was unfurled from the front row of Section 6 of Fenway Park’s Monster Seats.
“Racism is as American as baseball,” it read.
The sign remained visible for approximately two minutes before security personnel removed both the sign and four people — two men and two women, all roughly between the ages of 25 and 30 – from Fenway Park.
