World number one Novak Djokovic beat Roger Federer in four dramatic sets to win his second US Open and 10th Grand Slam title.
The Serb won 6-4 5-7 6-4 6-4 in New York, and will end the year with three of the four Grand Slam titles.
Djokovic, 28, held his nerve despite a heavily pro-Federer crowd at Flushing Meadows in New York.
The 34-year-old Swiss had been hoping to win his 18th major title and first for three years.
In a raucous New York night session atmosphere, after the start of play was delayed by more than three hours because of rain, Federer looked to have a real chance in the third set.
