Flushing Meadows, NY – Rain prevented the women's singles quarterfinals from commencing Tuesday at the 2011 U.S. Open, as both the day and night sessions were canceled at the USTA Billie Jean King National Tennis Center because of inclement weather.
Second-seeded 2010 U.S. Open runner-up Vera Zvonareva was scheduled to meet ninth-seeded 2010 French Open runner-up Samantha Stosur and 26th-seeded Italian Flavia Pennetta was supposed to face unseeded German Angelique Kerber on Day 9, but wet weather forced the postponement of the activities until Wednesday, where rain is in the forecast once again.
Zvonareva lost to Kim Clijsters in last year's finale in Flushing.
Two other women's quarterfinals will also be on the Day-10 schedule, as top- seeded Caroline Wozniacki is slated to meet 10th-seeded German Andrea Petkovic and 17th-seeded Russian Anastasia Pavlyuchenkova will take on 28th-seeded American great Serena Williams. Wozniacki was the 2009 U.S. Open runner-up to Clijsters, while the 13-time Grand Slam champion Williams is a three-time U.S. Open champion and a former runner-up in New York.
