Earlier, Leander Paes became the oldest man to win a grand slam title when he paired with Radek Stepanek to win the men's doubles title.
The 40-year-old Indian and his Czech partner, the fourth seeds, beat Alexander Peya of Austria and Brazil's Bruno Soares, the second seeds, 6-1 6-3.
Paes and Stepanek were winners of the 2012 Australian Open title and had ended the hopes of top seeds Bob and Mike Bryan, who were hoping to complete a calendar year grand slam, in the semifinals.
Paes had won the US Open title with Martin Damm in 2006 and Lukas Dlouhy in 2009 and now has eight men's doubles trophies at the majors as well as six mixed doubles crowns.
"I think the best advice I can give to anyone for doubles is get a partner from the Czech Republic!," Paes told the official tournament website.
"Radek helped me to get to be the oldest man to ever win a grand slam in the Open era. I thank him for that, and we are definitely not done. I'm going after 41 now, 42, and then 43."
