Listen to Mary J. Blige on iHeartRadio

(Yahoo!) - Major League Baseball better get ready for a world-class performance!

Yahoo Music can exclusively reveal that Mary J. Blige has been tapped to sing the national anthem at Game 1 of the 2013 World Series on October 23, when the Boston Red Sox and St. Louis Cardinals take the field at Fenway Park.

Naturally, the nine-time Grammy Award winner is thrilled to step up to the plate and sing.

"It is an honor to have the opportunity to perform the National Anthem," Blige, 42, dished. "I've conducted countless performances across the globe throughout my illustrious career, but performing the anthem at Yankees Stadium during the 2009 World Series was beyond a thrill, and so I'm looking forward to again being a part of baseball's great history."

While she's clearly a fan of America's favorite pastime, the "Black Nativity" actress has also been busy working on a hobby of her own: her new holiday album, "A Mary Christmas," which she released October 15.

Baseball fans are surely in for a treat since Blige is known for belting out powerhouse performances. We're sure she'll knock this one right outta the park. The question is: will she be rooting for the Sox or the Cardinals?

The 2013 MLB World Series airs on Fox, with Game 1 launching at 7:30 p.m. ET.
