Roger Federer claimed his record 15th grand slam crown and sixth Wimbledon title as he beat Andy Roddick 5-7 7-6 7-6 3-6 16-14 in an epic final on Sunday. Federer had been tied for grand slam wins with Pete Sampras, who watched the spellbinding clash on Centre Court. The second seed was pushed to the very limits by his big-serving opponent, with the climax coming in a marathon 30-game fifth set, CNN reported.
