Djokovic rolls into U.S. Open third round as Roddick announces retirement

Defending champion Novak Djokovic marched into the third round of the U.S. Open on Friday with a 6-2 6-1 6-2 victory over world number 112 Rogerio Dutra Silva.

The Serb was a class above the 28-year-old Brazilian as he stormed to victory in one hour, 39 minutes.

Second seed Djokovic dropped just two games in his opening-round win and Dutra Silva managed only three more as the Serb ripped his game apart.

Djokovic made just 14 unforced errors as he cruised through to a meeting with France's Julien Benneteau or American wildcard Dennis Novikov.


Roddick to retire, Federer and Serena play on

30-year-old Andy Roddick stunned the tennis world by announcing that the U.S. Open would be his last tournament on Thursday but there was no sign of the end of the road for his contemporaries Roger Federer and Serena Williams on day four at Flushing Meadows.

Top seed Federer absolutely dominated German Phau to win 6-2 6-3 6-2 in the opening match of Thursday's night session before paying tribute to Roddick, who he defeated in three Wimbledon finals.

Serena also remained on course for a fourth U.S. Open crown with an easy 6-2 6-4 victory over Maria Jose Martinez Sanchez.

Roddick's announcement of his impending retirement came shortly after France's fifth seed Jo-Wilfried Tsonga produced his worst match of the year to be the first big-name casualty of the men's draw.

The former world number one and U.S. Open champion said he realized during his first-round victory over Rhyne Williams that he had lost the desire to remain on tour.
