Roger Federer fought off a brave challenge from 35-year-old Andre Agassi on Sunday to beat the American 6-3, 2-6, 7-6, 6-1 and retain his U.S. Open title.
Seventh seed Agassi rocked the Swiss world number one by recovering from a set down to level the match and lead 4-2 in the third set, but Federer rebounded to become the first man in the professional era to win both Wimbledon and the U.S. Open in consecutive years.
"For me this is probably the most special Grand Slam final in my career," Federer said. "To play against Andre here in New York, it's a dream.
"I had to play my best match of the tournament, like I did last year, and like I always seem to do. I don't know how I do it, but it feels great."
Federer won the first set thanks to one break but Agassi, playing some of the best tennis of his career, roared back to level the match and then lead 4-2 in the third.
Federer broke back in the next game, though, and after winning the tiebreak 7-1, he stormed through the fourth set to win his sixth Grand Slam title.
Agassi, who came through three back-to-back five-set battles to reach the final, was pipped in the opening set but, with the crowd roaring him on, held in the first game of the second set and then played an almost flawless game to break Federer for the first time.
