Australia's Samantha Stosur has fallen short of the US Open doubles title, losing the final in New York today.
Zimbabwe's Cara Black completed a US Open doubles double, joining South African-born American Liezel Huber to defeat Stosur and American Lisa Raymond 6-3 7-6 (8-6).
Top seeds Black and Huber won their eighth doubles title of the year and first US Open crown.
"It's unbelievable. It's hard to find words to describe it," Black said.
Black teamed with India's Leander Paes to win the US Open mixed doubles crown with a 7-6 (8-6) 6-4 triumph over Huber and Britain's Jamie Murray in Thursday's final.
"Playing that match against her was one of the toughest matches I've ever had to play," Black said.
"I really wanted to win this one for her."
Huber and Black won the final four points of the match, saving two set points to level the tie-breaker before Huber hit a forehand winner and Raymond send a forehand long to give Huber and Black the $US420,000 ($A518,198) top prize.
Huber became a US citizen last year and said winning the title rivaled the day she became an American as the most special of her life.
"I'm proud to be an American," she said. "This is the second-proudest day for me."
Raymond and Stosur won the 2005 US Open doubles crown. Raymond also won the title in 2001 with Aussie Rennae Stubbs.
