(CNN) -- Serena Williams wasted little time in reaching the fourth round at Wimbledon on Friday as she dispatched Roberta Vinci of Italy 6-3 6-4 in a little over an hour.
A pumped up Serena wasted little time in dispatching Italian Vinci in straight sets.
The world number two was not at her best in the match on Court Two, but gave her Italian opponent few opportunities in their first meeting.
The two-time champion had dropped only nine games in her opening two matches on the grass at SW19 and quidkly moved a break of service ahead in the first set.
But Vinci took advantage of a double fault to break back only to be broken again on her own delivery in the next game.
The world number 53 held service on the next two occasions to force Williams to serve out for the opener, taking it with a thumping forehand after just 29 minutes.
Vinci was broken again at the start of the second set as Williams opened up a 4-1 lead before losing her service for the second time with another double fault.
The battling Vinci saved two match points before the American superstar wrapped it up in 67 minutes.
Williams will now play Daniela Hantuchova in the last 16 after the unseeded Slovakian beat her doubles partner Ai Sugiyama of Japan 6-4 6-3 in their third round clash.
Russian fourth seed Elena Dementieva also made the fourth round in fine style with a 6-1 6-2 demolition of compatriot Regina Kulikova, who was the last qualifier in her half of the draw.
But another Russian, seventh seed Vera Zvonareva, suffered an ankle injury, which forced her to pull out of her third round meeting with Virginie Razzano of France, the 26th seed.
Yet another Russian, 10th seed Nadia Petrova, ended the run of Maria Sharapova's conqueror Gisela Dulko 3-6 6-3 6-4, while eighth seed Victoria Azarenka of Belarus saw off Romanian Sorana Cirstea, the 28th seed, 7-6 6-3.
Meanwhile, 2007 Wimbledon runner-up Marion Bartoli of France, the 12th seed, has bowed out of the competition after losing 7-6 6-0 to Italy's Francesca Schiavone.
