U.S Open

Today is the beginning of U.S. Open,I am wondering who will be the winner this year,I wonder if Federer will claim once again the title after so many disappointed matched,except he won the gold medal in double last Beijing Olympic,or Rafael Nadal can protect his new Number 1 status?but wait,Novak Djokovic is waiting for his 2nd grandslam as well. Honestly,i want Rafael Nadal to win this time,he has to prove himself that he can play in any court,not only in clay or in grass but in hardcourt as well.He won the single gold medal in the Olympic so I guess it is a good start for him. To those who loves tennis like me,let us witness once again the excitement that this game will bring to us.Since it is U.S. Open,i hope any american will reach the final.
