Cara Black of Zimbabwe and Liezel Huber of the United States beat Lisa Raymond of the U.S. and Samantha Stosur of Australia 6-3, 7-6 (6) Sunday to win their first U.S. Open women's doubles championship.

"I'm not sure if I should sing the anthem or do a cartwheel or just encourage you guys to vote," Huber told the crowd during an on-court interview.

She was born in South Africa and became a U.S. citizen last year.

It's the fourth Grand Slam tournament title, and 20th title overall, as a team for the top-seeded Black and Huber. They also won Wimbledon in 2005 and 2007, and the Australian Open in 2007.

They didn't drop a set at Flushing Meadows.

Black also won this year's U.S. Open mixed doubles title, pairing with Leander Paes to beat Huber and Jamie Murray.

Black and Huber had to save two set points Sunday, when they trailed 6-4 in the tiebreaker. But they won the last four points of the match.

The 10th-seeded Raymond and Stosur, the 2005 U.S. Open champions, also were the runners-up at Wimbledon this year, losing to Venus and Serena Williams in that final. The Williams sisters didn't enter the U.S. Open doubles event.

In the junior finals, CoCo Vandeweghe of the U.S. defeated Gabriela Paz Franco of Venezuela 7-6 (3), 6-1 for the girls' title, and Grigor Dimitrov of Bulgaria beat Devin Britton of the U.S. 6-4, 6-3 for the boys' title.

The 16-year-old Vandeweghe is the niece of Kiki Vandeweghe, the general manager of the NBA's New Jersey Nets.
