Stanilas Wawrinka became the oldest US Open men’s champion when he defeated world number one Novak Djokovic to claim a third Grand Slam title on Sunday.
The 31-year-old third seed, triumphed 6-7, 6-4, 7-5, 6-3.
It has been 46 years since 35-year-old Ken Rosedale won in 1970 and the first over 30 to take the title since Pete Sampras in 2002.
It was the Swiss player’s first New York title, following his 2014 Australian Open triumph and 2015 Roland Garros crown.
Djokovic, the 2011 and 2015 champion, had been seeking a third Slam of the year and 13th major of his career.
Earlier on Saturday, Angelique Kerber won the women’s event, marking her rise to world number one with a gritty victory over Karolina Pliskova for her second Grand Slam title of the year.
Germany’s Kerber, the second seed, rallied from a break down in the third set to beat the hard-hitting 10th-seeded 6-3, 4-6, 6-4.
She added the US Open crown to the Australian Open title she claimed in January.
