First pitchers: Dirk, Bush, Staubach

We already knew Mavericks superstar Dirk Nowitzki would be throwing out the ceremonial first pitch before Saturday's Game 3 of the World Series. Now we know who will take part in the rest of the pregame ceremonies for Games 3-5 at Rangers Ballpark.

Former President George W. Bush, an ex-owner of the Rangers, will throw the first pitch to Rangers CEO Nolan Ryan before Sunday's Game 4. Cowboys legend Roger Staubach will do the honors before Monday's Game 5, with Rangers Hall of Famer Kenny Rogers on the receiving end.

The Rangers also announced who will be on national anthem duty. Game 3 goes to country artist Ronnie Dunn. Game 4 will be handled by actress/singer Zooey Deschanel. Actress/singer Demi Lovato, a North Texas native, will sing before Game 5.
