Serena Williams took just 61 minutes to book her place in the fourth round of the French Open as she destroyed Sorana Cirstea 6-0 6-2 at Roland Garros.
The American world No 1 extended her winning streak to 27 matches with another dominant performance in Paris.
Romanian Cirstea, the 26th seed, needed eight matches and 33 minutes to make her mark on the scoreboard, a feat that was greeted by sympathetic cheers from the crowd.
After her dismal start Cirstea even had two break points to lead 3-2 in the second set but Williams simply stepped on the accelerator again to clinch the victory.
Williams has dropped just six games in three matches as she goes in search of the 16th Grand Slam title of her career.
The 31-year-old, who won her only French Open title in 2002, will now play either Czech Petra Cetkovska or Italy's Roberta Vinci.
