体坛英语新闻：Top seeds Djokovic and Williams enter fourth round at Wimbledon

LONDON, June 29 (Xinhua) -- Top seeds Novak Djokovic and Serena Williams both claimed comfortable wins in their third round match and booked berths of last 16 at Wimbledon here on Saturday.

Djokovic committed only three unforced errors on his way to beating Jeremy Chardy 6-3, 6-2, 6-2 with a performance of near flawlessness.

Frenchman Chardy, who made a career-best run to the Australian Open quarterfinals this year, had to wait until he was trailing 4-1 in the third set before the 2011 Wimbledon champion would throw in a double fault, his first unforced error of the match.

The Serb dropped six points on serve throughout, with 38 winners to Chardy's 18.

"When everything works well it's a fantastic feeling," Djokovic said. "I felt great from the start till the end. I had that super focus, you know, and tried to be out there every point and not allow him to come back to the match or to have any chance."

"That was incredible for me. I enjoyed every moment of it, especially at the end. I managed to read his serve. Everything went well. So when you play that well, obviously you feel great, you feel confident," he said. "This kind of performance came in the right time for me."

Djokovic will next face German veteran Tommy Haas for a place in the quarterfinals.

Williams breezed past 42-year-old Kimiko Date-Krumm of Japan 6-2, 6-0.

Kimiko, who made her Wimbledon debut 24 years ago, had announced her first ambition was to extend the proceedings beyond the one-hour mark. And the match lasted one hour one minute.

Serena paid tribute to the Japanese, the oldest woman in the Open era to reached the third round at Wimbledon. "I never thought I would play into my thirties, which is why I have so much respect for Kimiko. She is so fit and so good."

Fourth seed David Ferrer fought a hard battle before beating 26th seed Alexandr Dolgopolov 6-7(6), 7-6(5), 2-6, 6-1, 6-2 in three hours and 12 minutes.

"It was a very hard match, very tough," said 31-year-old Ferrer. "Dolgo is never easy to beat. I tried to fight a lot to be focused in the bad moments and finally I won."
