Novak Djokovic got a full match in but barely a full workout as the world number one romped past unseeded Carlos Berlocq of Argentina 6-0, 6-0, 6-2 on Thursday to charge into the third round of the U.S. Open.
Not that the 24-year-old Serb was complaining after an arduous though brilliantly successful season that has produced a 59-2 record to rival the greatest of all tennis campaigns.
"The first two sets were ideal. I could not play better," the top seed Djokovic said. "I was ending the points when I needed to. I was making a lot of winners. My serve was okay. The return was great.
"I felt fantastic on the court. Everything seems fun and seems enjoyable when you're playing such good tennis."
Djokovic had won his first round match when Irish qualifier Conor Niland retired trailing 6-0, 5-1, suffering a case of food poisoning.
Djokovic spent a bit more time against Berlocq, with the greatest suspense being whether the soft-hitting Argentine would be able to win a game from the top seed. Berlocq broke through in the 15th game and won a standing ovation from the crowd in a match in which the off-court friends played some entertaining rallies and traded gentlemanly volleys from close range.
Roger Federer, Caroline Wozniacki and Serena Williams had earlier swept into the third round with the same sort of ruthless performances that made them the king and queen of tennis.
Federer, already a five-time champion on the hardcourts of New York, demolished Israel's Dudi Sela 6-3, 6-2, 6-2 in 77 minutes. Williams was just as unforgiving. She thrashed Michaella Krajicek of the Netherlands 6-0, 6-1 in less than an hour, racing around like the court like a teenager instead of a 29-year-old on the comeback trail.
One way to get faster is you can pretend there's a check for a million dollars there tax-free, and just go run it down," she explained.
Sixth seeds Sania Mirza and Mahesh Bhupathi made a shock first-round exit from the mixed doubles event but Somdev Devvarman and his partner entered the men's doubles second round.
Sania and Bhupathi lost 3-6, 6-7 (5) to the Czech pair of Lucie Hradecka and Frantisek Cermak in a contest that lasted a little over an hour.
However, Somdev, who lost in the men's singles opening round against Andy Murray, ensured that India didn't go winless on day four. He and his Filipino partner Treat Conrad Huey defeated Russians Igor Andreev and Igor Kunitsyn 6-3, 6-4 to enter the men's doubles second round.
