Mary J. Blige sang the national anthem before Game 1 of the MLB World Series between the Boston Red Sox and St. Louis Cardinals. Obviously, she was not the focal point of the night's events, but she still showcased her powerful vocals to the crowd at Fenway Park, belting her heart out and proving why she is considered one of the greats. Of course, this was not her first time singing the national anthem during the World Series; she did so at Yankee Stadium back in 2009.

Meanwhile, the Red Sox defeated the Cardinals in Game 1, 8-1.
