Novak Djokovic vanquished long-time rival Roger Federer 6-4 5-7 6-4 6-4 to win the U.S. Open on Sunday to cap one of greatest grand slam seasons of all-time.

The victory gave Djokovic three of the year's four grand slam titles with a loss to Stan Wawrinka in the French Open final his only blemish.

It was the 10th career major for Djokovic but only his second U.S. Open.

The 28-year-old Serb had known more frustration than success on the Flushing Meadows hardcourts having previously reached the final five times and lifting the trophy just once in 2011.

It was more grand slam misery for the 34-year-old Swiss who, for the second consecutive grand slam, made to the final only to be denied an 18th title by Djokovic.
