PARIS (AFP) - Serena Williams coasted into the last 16 of the French Open on Friday with a 6-0, 6-2 win over Sorana Cirstea of Romania.
In another Roland Garros mismatch involving the in-form top seed, the 31-year-old American was in control from the start on the Suzanne Lenglen showcourt, winning the first set in just 23 minutes.
Cirstea was facing an embarrassing whitewash, but she rallied briefly at the start of the second set and even had two break points to lead 3-2.
But she failed to take either of these and Williams simply stepped on the accelerator again to race away and end the remaining pockets of resistance from the Romanian.
The win was the 27th in a row for Williams - the best unbeaten run of her career - and it took her into a fourth-round match against the winner of the tie between Roberta Vinci of Italy and Petra Cetkovska of the Czech Republic.
She has dropped just six games in three matches as she campaigns for the 16th Grand Slam title of her career, but just the second in Paris where she last won in 2002.
Williams reached the semi-finals at Roland Garros the following year and since then has fallen four times at the quarter-final stage, but last year she was upset in the first round by Frenchwoman Virginie Razzano.
