US Open 2015: Novak Djokovic beats Roger Federer in final

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 tennis majors.

Djokovic, 28, kept his nerve in front of a heavily pro-Federer crowd at Flushing Meadows.

The 34-year-old Swiss had been hoping to win his 18th major title and his first for three years.

In a raucous night session on Arthur Ashe Stadium, 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.

However Djokovic broke the Federer serve six times and saved 19 of 23 break points as he battled his way to a 27th win in 28 Grand Slam matches this year.
