For the second time in two tries, Venus and Serena won the doubles gold, beating a team from Spain here Sunday at the Olympic tennis complex. They did the same thing eight years ago in Sydney. And they did it in similar fashion Sunday. Sunday's final was 6-2, 6-0 over Anabel Medina Garrigues and Virginia Ruano Pascual. The final in Sydney was 6-1, 6-1 over the Dutch team of Kristie Boogert and Miriam Oremans.
