Venus Williams managed to make it to the mixed doubles final with Bob Bryan, ensuring an American presence, but was outplayed by the number 9 ranked pair of Andy Ram and Vera Zvonareva.
Also the Bryan brothers claimed the Men's doubles Title, ensuring Bob Bryan picked up a winner and runner up plate.
When Andy Murray played Baghdatis, maybe he was tired from his mixed doubles match earlier in the day, that contributed to his game being not on a par with that when he played Andy Roddick, and lead to his exit from the singles draw (and mixed doubles), maybe he can't yet play two matches back to back and needs to work on his fitness. John McEnroe was saying that he can play good tennis for 2 hours then he begins to tire.
I think there could be an upset in the Men's singles, and Nadal will push Federer all the way for the title. Federer is expected to win, Nadal is the underdog so there won't be so much pressure on him.
