Roger Federer won his record 15th Grand Slam title Sunday, outlasting Andy Roddick for his sixth Wimbledon championship in a marathon match that went to 16-14 in the fifth set. Federer served a career-high 50 aces and overcame the resilient American 5-7, 7-6 (6), 7-6 (5), 3-6, 16-14 to break the record of major titles he shared with Pete Sampras and enhance his reputation as perhaps the greatest player in history.
