Williams, who is competing in singles and with her sister Venus in women`s doubles, had repeatedly said she also wanted to play mixed doubles. Andy Roddick, John Isner and the Bryans all courted her as a partner. But she became coy about the subject in recent weeks and wasn`t on the list when teams were nominated Tuesday. Competition begins Wednesday with 16 teams, meaning only two victories are needed to reach the medal round. Agencies
