USTA Names Men's and Women's Olympics Teams

The United States Tennis Association today named the members of the men's and women's teams who will represent the United States at the London Olympics. As I predicted, Venus Williams and Serena Williams were named to the team in both singles and doubles. Interestingly, John Isner and Andy Roddick  (as well as Mike and Bob Bryan, of course) were named to the doubles team, so I wonder who will get to play with Serena in the new mixed-doubles competition?
