Novak Djokovic produced an impeccable performance to beat Juan Martin del Potro in the US Open final and win his 14th Grand Slam title.
The 31-year-old Serb won 6-3 7-6 (7-4) 6-3 to earn his third triumph in New York and equal American great Pete Sampras' haul of major trophies.
Djokovic, who won Wimbledon in July, will climb to fourth in the world after back-to-back Grand Slam victories.
Only great rivals Roger Federer (20) and Rafael Nadal (17) have won more.
Argentine third seed Del Potro, 29, was playing his first Grand Slam final since winning the 2009 US Open, having almost quit the game in 2015 because of multiple wrist injures.
