Vera Zvonareva into the quarters

And, more importantly for tennis fans who don't want another late night with school and work commencing tomorrow, Zvonareva cleared the Ashe Stadium court in a tidy 67 minutes. Her 6-1, 6-2 win over unseeded Andrea Petkovic was never in doubt, and the No. 7 seed Zvonareva, the runner-up at Wimbledon in July, will face Kaia Kanepi in the quarterfinals.

Now, after a short break, Roger Federer will take the court for his fourth-round match with Jurgen Melzer.
