Djokovic clinches US Open Title Over Federer

After stopping Federer in four sets in this year's Wimbledon final, Djokovic did the same on Sunday, prevailing against an inspired opponent and a hostile crowd in Arthur Ashe Stadium to underscore his status as the world's No. 1 player.

Djokovic's 6-4, 5-7, 6-4, 6-4 victory gave him a second US Open singles title and a 10th grand slam singles crown, moving him into a tie with Bill Tilden for seventh place on the career list.

Federer remains on top of that pecking order with 17, but Djokovic has prevented him from adding to his record total.

He is playing remarkable tennis at age 34, but Djokovic, at 28, is in his prime and remains one of the great tennis conundrums for any opponent with his tactical versatility and peerless defensive skills.

"A massive challenge," Federer conceded after his latest defeat.
