Wimbledon:Serena Williams clinically booked her place in the last 16 of Wimbledon with a straight sets victory over Roberta Vinci on Centre Court.
The two-time Wimbledon champion and number two seed blew her unseeded Italian opponent away 6-3 6-4 inside 67 minutes and will face Daniela Hantuchova for a place in the quarter-finals.
Speaking after her victory over world number 53 Vinci, Williams said: "I don't think I played great today at all.
"I'm just glad to have got through it and go onto the next match."
Unseeded Slovakian Hantuchova, who knocked out Briton's Laura Robson in the first round, recorded a 6-4 6-3 win over doubles partner Ai Sugiyama in their first round match on Court 18.
Russian fourth seed Elena Dementieva brushed past compatriot Regina Kulikova with an emphatic 6-1 6-2 victory in their third round clash.
Dementieva, a semi-finalist at SW19 last year, will play another Russian, Elena Vesnina in the next round after she ousted Slovakia's Dominika Cibulkova 7-5 4-6 6-4.
Dementieva said afterwards: "I think it was a good match, we'd never played before but I felt from the beginning I was very focused and aggressive and satisfied with the way I was playing.
"Even though it was 6-1 6-2 we had some tough rallies in the second set and I think it was a good test for the next round.
"It was great being in the semis here for the first time last year and hopefully that experience will help me."
There was early disappointment for number seven seed Vera Zvonareva on day five when she was forced to pull out of her third-round match against Virginie Razzano due to an ankle injury.
Eastbourne runner-up Razzano, the 26th seed, will play either French compatriot Marion Bartoli or Francesca Schiavone in the fourth round.
Number 10 seed Nadia Petrova produced an inspired comeback to overcome Argentina's Gisela Dulko on Court Three.
The feisty Russian battled back to win 3-6 6-3 6-4 and will meet eighth seed compatriot Victoria Azaranka next up.
Azarenka saw off Sorana-Micaela Cirstea 7-6 6-3 on Centre Court to keep her hopes of a maiden Grand Slam title alive.
