A day after Victoria Azarenka collapsed on court during a singles match at the U.S. Open, she and partner Dinara Safina pulled out of women's doubles. Azarenka and Safina were originally scheduled to face the ninth-seeded pair of Cara Black and Anastasia Rodionova in the first round of doubles Thursday. But the tournament said Black and Rodionova instead would play Alberta Brianti and Urszula Radwanska.
