New York: Novak Djokovic moved into the third round of the US Open with an easy win over 112th-ranked Rogerio Dutra Silva of Brazil.
The defending champion won 6-2, 6-1, 6-2.
"Definitely doesn`t feel great, spending 15 minutes for one game in this heat," Djokovic said.
Nevertheless, Djokovic finished with more than twice as many winners, 29, as unforced errors, 14. He needed a little more than 90 minutes all told to make sure he would keep intact his record of never having lost to a player ranked outside the top 100 at a major tournament.
"I didn`t know much about my opponent. Never saw him play. So that could have been, you know, a difficulty at the start in order to figure out what his game plan is," Djokovic said. "But I have played well from the start to the end."
The second-seeded Serb has lost a total of seven games through two matches this year at the U.S. Open.
"Obviously, I want to spend (as little) time as possible on the court," Djokovic said. "I have played a lot of tennis, a lot of matches, through the course of this summer."
That includes a runner-up finish to Rafael Nadal at the French Open, and a semifinal loss to eventual champion Roger Federer at Wimbledon, following a title at the Australian Open in January.
Dutra Silva, who never has reached the third round at a Grand Slam tournament, was impressed by Djokovic`s play in Arthur Ashe Stadium.
"It`s tough to hurt him. I tried, many ways, to hurt him. And actually I can`t do that," Dutra Silva said with a smile. "I tried to play baseline. I tried to hit and hit the ball. I tried to play fast. It`s so tough."
Djokovic won 37 of 41 points on first serves and never faced a break point all match.
Dutra Silva said that while Djokovic`s first serves were hard to handle — the Serb did hit six aces — it was what happened once the ball was in play that was more problematic.
"When I put the ball in the court," Dutra Silva said, "I was in big trouble, you know?"
