|Defending champion Stosur serves to her opponent|
Julia Goerges and Nadia Petrova defeated Alisa Kleybanova and Yan Zi 2-6, 6-4, 10-3 in the first round of doubles play. Petrova won the doubles championship in both 2009 and 2010, but until yesterday, she had never played doubles with Goerges. In fact, as of Monday, Petrova and Goerges had never even practiced together, and Petrova was understandably concerned about the defense of her title. The Russian, who is also the 7th seed in singles, was troubled by an episode of vertigo in Miami, and is still undergoing treatment. She won her second round singles match easily yesterday morning.
Top seeds Caroline Wozniacki, Sam Stosur and Jelena Jankovic all won in straight sets on Wednesday, and 10th seed Daniela Hantuchova dropped only one game in her second round match.
