Federer and Roddick among quarterfinalists at Wimbledon

WIMBLEDON, England (AP) — Five-time champion Roger Federer advanced to the quarterfinals on a day Wimbledon went indoors.

Some 90 minutes after Federer was done Monday, rain halted play with Amelie Mauresmo leading top-ranked Dinara Safina, 6-4, 1-4, and officials ordered the new retractable roof closed for the remainder of the match. Safina rallied to win, 4-6, 6-3, 6-4.

Federer hit 23 aces, never lost serve and beat familiar foil Robin Soderling 6-4, 7-6 (5), 7-6 (5). Federer improved to 11-0 against Soderling, including a victory in the French Open final three weeks ago to complete a career Grand Slam.

This time the No. 2-seeded Federer came through on a handful of key points. He earned the only service break of the match in the ninth game of the opening set, when Soderling committed five unforced errors to fall behind for good, 5-4.

Soderling led in the final tiebreaker but double-faulted on the next-to-last point, then hit an errant return.

“Today was hard to get through a really dangerous match,” Federer said. “Not many rallies, so maybe not as much fun for the people. But I stayed calm, waited for my chance.”

The Williams sisters remained on course to play an all-family final for the second year in a row.

Five-time champion Venus led 6-1, love-1 when Ana Ivanovic retired with a left thigh injury. Two-time champion Serena beat Daniela Hantuchova 6-3, 6-1. Venus beat Serena in last year’s final.

American 17-year-old Melanie Oudin’s surprising run ended when she lost to No. 11-seeded Agnieszka Radwanska, 6-4, 7-5.

In men’s play, No. 6-seeded Andy Roddick hit 24 aces, never faced a break point and defeated No. 20 Tomas Berdych 7-6 (4), 6-4, 6-3.

“I’m having so much fun,” said Roddick, a two-time runner-up to Federer. “I love playing here. It really is an honor, and that’s something that is never lost on me.”

Roddick’s opponent Wednesday will be 2002 champion Lleyton Hewitt, who rallied from a two-set deficit for the sixth time in his career to beat No. 23 Radek Stepanek, 4-6, 2-6, 6-1, 6-2, 6-2.

No. 22 Ivo Karlovic hit 35 aces and beat No. 7 Fernando Verdasco 7-6 (5), 6-7 (4), 6-3, 7-6 (9). The 6-foot-10 Karlovic, who has yet to lose his serve in four matches, will face Federer on Wednesday.

No. 4 Novak Djokovic broke seven times and beat Dudi Sela 6-2, 6-4, 6-1.

Soderling had only two break-point chances against Federer — both at 4-all in the third set — and failed to put either return in play. Federer lost just eight points on his first serve and committed only eight unforced errors in the match.

Federer said he has regained the confidence he lacked early this year.

“No signs of panics, what I maybe had, you know, six months ago when I played. I would just feel uneasy. I wouldn’t be exactly sure what the right plays were. Now I feel perfect.”

He needs three more victories this week for his 15th major title, which would break the record he shares with Pete Sampras.

Ivanovic said she hurt her thigh hitting an ace to erase a break point in the opening game of the second set.

“I didn’t feel anything up until that point,” she said. “When I landed, I just felt a sharp pain on my inner thigh, and I couldn’t step on my leg ever since.”

Ivanovic took a 10-minute break to have her thigh taped by a trainer. She returned for two more points, but after hitting a service winner to take the game, she began crying as she walked to her chair and told the umpire she was retiring.

Then she hugged a sympathetic Williams.

“I don’t even know the last time that I had these circumstances,” Williams said. “I don’t think ever in a Slam. I think she was in a lot of pain. You know me — I’m one of those players, I just only pay attention to what’s going on my side of the net. But today I felt really sad for her actually. She was really upset. This is Wimbledon. It’s the last place you want to have an injury that you can’t overcome. So I’m wishing her a lot of luck in her recovery.”
