Novak Djokovic continued the defence of his US Open title with a routine straight-sets victory over Brazil's Rogerio Dutra Silva.

Second seed Djokovic, of Serbia, took just one hour and 39 minutes to secure a 6-1 6-2 6-1 second-round win.

Andy Roddick's retirement plans are on hold after the American comfortably beat Bernard Tomic 6-3 6-4 6-0.

Spain's David Ferrer, the number four seed, overcame Dutch qualifier Igor Sijsling 6-2 6-3 7-6 (14-12).

Djokovic has spent less than three hours on court in winning his first two matches, having eased past Italy's Paolo Lorenzi on Tuesday.

The Serbian said: "I didn't know much about my opponent; I'd never seen him play.

"Even if the scoreline doesn't indicate it, it was a tough match. I played well from the start to the end."

Roddick, who announced this week that he will retire at the end of the tournament, was cheered by a patriotic New York crowd when he walked on court at Arthur Ashe Stadium.

The spectators were on their feet at the end of the match, applauding the former world number one's dominant 87-minute victory over Australian teenager Tomic.

Roddick admitted he struggled to control his emotions when he watched a television feature about his career before the match.

"It got to me a little bit. I had to get away from that," said the 30-year-old, who hit 10 aces and 24 winners to book a third-round meeting with Italy's Fabio Fogini.

"That was a different kind of nerves than I've had before."

Tomic was accused of not trying by seven-time Grand Slam winner and TV commentator John McEnroe, and became involved in an angry exchange with a journalist at the post-match news conference.

Asked about McEnroes's comments, Tomic said: "He's probably right."

But when pressed, he responded: "That's how I play. If you think that's that, it's up to you. What is your name?" When the reporter told him, Tomic replied: "I'll remember you."
