Spain's Virginia Ruano Pascual and Argentine Paola Suarez confirmed their status as the world's number one women's pair by winning their fourth French Open doubles title on Sunday.
The top seeds, playing their sixth consecutive final at Roland Garros, beat second seeds Cara Black of Zimbabwe and Liezel Huber of South Africa 4-6, 6-3, 6-3.
Ruano Pascual and Suarez have now played 13 Grand Slam finals together, winning eight.
Black and Huber, playing their first Grand Slam doubles final together and teaming up at a major tournament for the second time, had a great start but their experienced opponents then took control of the match.
"We had to fight hard," said Ruano Pascual. "They played very well. They gave us many problems in the beginning. As the match progressed we understood how we had to play. We changed our game and it worked."
Ruano Pascual, 31, and Suarez, 28, have won 28 titles as a team. They had triumphed in Paris before in 2001, 2002 and last year.
"We've been playing together for a very long time," said Ruano Pascual.
"We know each other very well. We know exactly what the other one is going to do at each moment. We feel good together even outside the court and that brings us a lot."
