Wozniacki dominant, Zvonareva out

Caroline Wozniacki looked every inch the world number one as she dismissed Virginie Razzano in their second-round match on Wimbledon's Court Two.

The 20-year-old Dane, looking to dispel the theory that the top-ranked woman rarely challenges at a grand slam, needed just an hour and 11 minutes to take an impressive 6-1 6-3 victory.
Her serve worked well throughout but it was the quality of her groundstrokes - in particular her backhand - that caught the eye and she only made one unforced error on her way to the win.
Razzano, whose first-round win over Sania Mirza was her first since the death of her fiance last month, served out the opening game with some ease and showed little sign that she was about to lose the next six to go a set down.
She even played the point of the second game, smashing a winner after drawing Wozniacki into a lob, but she lost her serve in the third when she netted after her opponent earned a break point by coming to the net.
The break was cemented with some more impressive serve-volleying, and another break duly followed when Razzano netted after a gruelling rally.
Wozniacki's backhand was working like a dream and was pinning Razzano behind the baseline, with 4-1 quickly becoming 5-1 before the set was won with a third break of serve, teed up by a wonderful point where she defended doggedly before chasing down a drop shot and punched home a forehand winner.
The top seed's winning streak ended at seven games early in the second set as Razzano clung on to her serve, but the Frenchwoman's forehand let her down in the next game as Wozniacki held again.
Razzano, the world number 96, had to be encouraged up from the floor by the crowd midway through the fourth game after she netted with a simple volley, an error that allowed Wozniacki back to 30-30 on her way to a fourth break of the match.
And with Wozniacki giving nothing away on her serve, there was no way back for Razzano, even though she saved three match points during a game that had to be halted when a ball from a neighbouring match flew on to the court.
Tsvetana Pironkova produced a major upset at Wimbledon for the second year running as she beat Vera Zvonareva to set up a fourth-round clash with her superstar victim from last year - Venus Williams.
Pironkova, from Belarus, has struggled up to live up to the acclaim which followed her straight-sets win over Williams in 2010.
But she showed off her class when she beat Russian number two seed Zvonareva 6-2 6-3 on Court Two in a repeat of last year's semi-final, avenging the result from that match.
Williams, the five-time champion, is determined there will be no repeat of last year's shock defeat to Pironkova when the pair meet again on Monday in the last 16.
Britain's hopes for a local champion in the ladies singles were crushed on Friday after Elena Baltacha and Laura Robson both bowed out at the hands of Peng Shuai and Maria Sharapova respectively.
Number nine seed Marion Bartoli avoided an upset as she came from a set down to see off Lourdes Dominguez Lino, while Victoria Azarenka of Belarus beat Slovakian 25th seed Daniel Hantuchova 6-3 3-6 6-2.
Other notable names to fall were Svetlana Kuznetsova, the 19th seed, who was beaten by Yanina Wickmayer, and Andrea Petkovic, who was dumped out in straight sets by Ksenia Pervak.
On Court 18, title dark horse Petra Kvitova swept past Roberta Vinci.
Nadia Petrova beat Kateryna Bondarenko on Court 14 in Friday's other completed match while Francesca Schiavone and Tamira Paszek's match was going with serve in the third set when rain brought a halt to their match on Court 12.
