Doubles title for Williams
Serena and Venus too strong for Peschke and Srebotnik
Venus and Serena Williams landed their fourth consecutive grand slam doubles title with a 6-2 6-3 victory over Kveta Peschke and Katarina Srebotnik at the French Open.
The Americans wrapped up victory in 73 minutes to win their 12th grand slam title together, adding to last year's trophies at Wimbledon and Flushing Meadows as well in Melbourne in January.
The sisters become only the third partnership in the history of the women's game to hold all four slams at the same time.
Martina Navratilova and Pam Shriver did it in 1983-84, while Gigi Fernandez and Natasha Zvereva repeated the feat in 1992-93.
The top seeds will become the number one-ranked doubles pairing on Monday, meaning Serena will be only the sixth woman to hold top spot in singles and doubles at the same time.
