Venus Williams won a maiden Billie Jean King Cup title and a $400,000 prize with victory at Madison Square Garden in New York City.
The American took the showpiece four-player tournament by beating Svetlana Kuznetsova in the semi-finals and US Open champion Kim Clijsters 6-4 3-6 7-5 in the final.
Williams arrived in off the back of retaining her Acapulco crown and held off a brave fightback by Clijsters to win a decisive break in game 12 of the final in front of a near-12,000 strong crowd.
"I always feel really confident on match point, so I love getting to that match point," said the world number five. "At quadruple match point I felt nice."
