Top seed Roger Federer of Switzerland sailed into the men's singles last 16 at the Wimbledon Championships by beating French veteran Arnaud Clement in straight sets on Friday.

The six-time Wimbledon champion crushed the 32-year-old Frenchman 6-2, 6-4, 6-2, going to face Austrian Jurgen Melzer in the fourth round.

Federer saved the only break point against him, hit 29 winners, made only 12 unforced errors and left Center Court to a rousing standing ovation.

"I get standing ovations 99 percent of the time - doesn't matter if the performance was great or not so great," he said. "I think they're happy to see me, and they love tennis. ... But of course, when I end up winning, and they give me a reception like this, it feels good at the heart."

Melzer, seeded 16th, came from one set down to defeated the 22nd seed Feliciano Lopez of Spain 4-6, 6-3, 6-2, 6-4.

One day after winning the longest tennis match in history, John Isner lost to unseeded Thiemo de Bakker of the Netherlands 6-0, 6-3, 6-2 in just one hour and 14 minutes.

Isner claimed an epic three-day victory over Nicolas Mahut, which lasted 11 hours, 5 minutes and went to 70-68 in the fifth set.

What's more, Isner served no aces Friday after hitting a record 112 against Mahut.

"I've never been this exhausted before," Isner said. "Mentally and physically, I was obviously a bit drained. I just didn't have much in the way of my legs. I was just low on fuel out there. Didn't really have a chance."
