In Day Four action at the 2011 U.S. Open, the top seeds on both the men's and women's sides of the draw played under the lights of Arthur Ashe Stadium and both advanced to the next round.
On the men's side, top-seeded Serbian Novak Djokovic was a 6-0, 6-0, 6-2 winner over Argentina's Carlos Berlocq.
"The crowd got involved in the third set ... it was great," said Djokovic of his match against Berlocq. "We needed that in the match. "Berlocq started playing better. He started making some winners, some good shots. And the crowd felt that was the point of the match where they should get energized and get involved in the match."
Djokovic moves his record on the year to an amazing 59-2, and advances to face Russian Nikolay Davydenko who defeated Italy's Potito Starace, 6-2, 6-4, 7-5. Davydenko is a four-time Grand Slam semifinalist, including twice at the U.S. Open.
"Nikolay has been a top five player for a couple years. I think he's underrated ... one of those players that people are not talking about too much," said Djokovic of his next-round opponent. "He deserves more credit than he really gets. He's a really good player and has won many titles in his career. He definitely cannot be underestimated. If he is on a roll, he can be very dangerous because he plays very fast."
Women's top-seed Caroline Wozniacki of Dernmark was a 6-2, 6-0 winner over Arantxa Rus from The Netherlands. Awaiting Wozniacki in the next round is American Vania King who was a 6-2, 6-0 winner on Court 17 over the number 29 seed, Australian Jarmila Gajdosova.
"She's definitely getting a lot of balls back, and it's important to stay aggressive, but not too aggressive," said Wozniacki of her next round opponent King. "I just need to dictate, but have control over the points. King is definitely a player that is not easy to beat and I'm looking forward to the match."
Other highlights of the day on the men's side included the number three-seed Roger Federer of Switzerland defeating Israel's Dudi Sela, 6-3, 6-2, 6-2; France's Gael Monfils, the number seven seed, was upset by Spain's Juan Carlos Ferrero, 6-7, 7-5, 7-6, 4-6, 4-6 in a five-hour-plus marathon; the number eight seed, American Mardy Fish, was a 6-2, 6-2, 6-4 winner over Tunisia's Malek Jaziri at Louis Armstrong Stadium; and the number nine seed, Tomas Berdych of the Czech Republic was a 7-5, 6-0, 6-0 winner over Italy's Fabio Fognini.
On the women's side of the draw, the number 28 seed, American Serena Williams continued her comeback with a dominating 6-0, 6-1 win over Michaella Krajicek from The Netherlands; the number seven seed, Francesca Schiavone from Italy was a 6-1, 6-1 winner over Croatian Mirjana Lucic; the number four seeded Victoria Azarenka from Belarus was a 6-4, 6-3 winner over Argentina's Gisela Dulko; and the number 11 seed, Serbian Jelena Jankovic, advanced with a 6-3, 6-4 win over Australian Jelena Dokic.
