It got a bit dicey toward the end, but Elena Vesnina managed to pull off an upset of one of the tour's hottest players today in New Haven. She defeated 9th seed Sam Stosur 3-6, 6-3, 6-4. Though she has had her ups and downs, this has been a really good season for Vesnina.
Also advancing to the quarterfinals today were 3rd seed Flavia Pennetta, who played a close match against Iveta Benesova, and 2nd seed Caroline Wozniacki, who defeated Anastasia Pavlyuchenkova. Agnieszka Radwanska retired against Virginie Razzano because of an inflamed wrist tendon, and top seed Svetlana Kuznetsova had to fight for almost two hours and forty minutes to ward off Yanina Wickmayer.
