LONDON, July 5 (Reuters) - Switzerland's Roger Federer beat Andy Roddick in one of the most extraordinary finals ever seen at Wimbledon on Sunday, holding off an incredible challenge from the American to win 5-7 7-6 7-6 3-6 16-14.

The final set alone of an unforgettable Centre Court duel lasted 95 minutes before Roddick's mishit forehand gave Federer his sixth Wimbledon title and the record of 15 grand slam titles he so cherished.

Fittingly, Pete Sampras, the only other man to have previously won 14 slams, was sat in the Royal Box as a match of unrelenting drama stretched into a fifth hour.

"Andy I want to say you're going to come back and win one, I'm sure," Federer said on court as a shattered Roddick contemplated his third defeat to Federer in a Wimbledon final.

"Today I was on the lucky side. It feels funny to have the trophy back. It feels great. It was a crazy match, my head's still spinning. It's an unbelievable moment in my career."
