Lady Antebellum had the honor of singing the national anthem at Game 2 of the World Series in San Francisco on Thursday.

The Grammy-winning trio, comprised of Charles Kelley, Hillary Scott and Dave Haywood, sang to open the game between the San Francisco Giants and Texas Rangers. They followed R&B star John Legend, who performed for the opening game on Wednesday, October 27. Kelly Clarkson will follow Lady A at Game 3 of the series, which will be held in her home state of Texas.

"Honored to be asked to sing the national anthem tomorrow night at game 2 of world series," Dave tweeted on Wednesday. "My only question is who do we root for?!"

Turns out they are having to make much bigger decisions than what sports team to cheer on. After opening for several big acts, including Tim McGraw and Martina McBride, the band decided to take their own show on the road earlier this year -- and quickly realized the enormity of this step in their career. "It's a lot more responsibility than I think you realize until you start embarking on it and making all these decisions," Hillary tells The Boot. "It makes us appreciate the people we've opened for over the years a lot more. You just have to think about every little thing from what people are eating to the set list. Everything. It runs the gamut."

The band are certainly having a jam-packed fall. In addition to criss-crossing the country with their tour, the trio are making the awards show circuit. First they'll hit the CMA Awards on November 9, where they are up for six trophies, including Entertainer of the Year, and they will also perform. At the American Music Awards held on November 21, Lady A are nominated for five awards, which ties them with rapper Eminem for the most nods. They also tie Easton Corbin in nominations, with seven, for the first American Country Awards, which will be held December 6 in Las Vegas.
