Today in the third round, Andy Roddick of the USA defeated Andreas Seppi of Italy 6-2, 7-5, 7-6(7-4). Roddick could meet third seeded Novak Djokovic of Serbia in the quarterfinals and defending champion Roger Federer of Switzerland in the semifinals.

On the other half of the men's draw, Sam Querrey of the USA and Fish could face each other in the quarterfinals, but both must first get past two of the toughest fighters in the draw. In tomorrow's fourth round, Fish meets the powerful and athletic Frenchman Gael Monfils while Querrey takes on world number one Rafael Nadal of Spain.

In women's play tomorrow, both of America's Williams sisters, Venus Williams and Serena Williams will play fourth round matches. Should both of the sisters win, they would then face off in the quarterfinals; an early meeting due to a slip in both of their rankings. Serena however will move from three to one in the WTA Tour rankings should she take the US Open title.

Roddick won the US Open title in 2003. Venus Williams struck victory in 2000 and 2001, while Serena Williams won in 1999 and 2002.
