Martina Navratilova's bid to become the oldest woman to win a US Open title was ended when she and Svetlana Kuznetsova were beaten in the women's doubles final.
Navratilova was going for her 59th Grand Slam title
Spain's Virginia Ruano-Pascual and Argentina's Paola Suarez, seeded second, beat Kuznetsova and Navratilova 6-2 6-3 to capture the title.
Navratilova, 46, would have been the oldest female title winner of the event, breaking the mark set by Margaret Osborne duPont, who was 42 when she won the 1960 mixed doubles crown in a pre-Open era competition.
But under cloudless skies on the Arthur Ashe stadium court the American winner of a record 171 doubles and 166 singles titles and her Russian partner were outplayed by the defending champions.
"They never really let us into the match. We tried our best and it is just a great bonus to be here," Navratilova said.
"If you guys have anything to do with it then I guess I will be back," she told the cheering crowd.
Having lost in the final at the last three Grand Slams this year, Suarez and Ruano-Pascal were relieved to win.
"We really wanted to win one this year," Ruano Pascual said. "We play very good today, one of the best matches these two weeks."
Navratilova first played at the US Open 30 years ago. She won the doubles title on six occasions, with Pam Shriver in 1983, 1984, 1986 and 1987, with Hana Mandlikova in 1989 and with Gigi Fernandez in 1990.
She also won four US singles titles in 1983, 1984, 1986 and 1987.
This year, as a doubles player only, she has won five titles and with her mixed doubles wins at the Australian Open and Wimbledon with Leander Paes became the oldest player to win any Grand Slam title.
