8th seeds Bethanie Mattek-Sands and Yan Zi began their Australian Open quarterfinal match yesterday by staying close to the 2nd-seeded Williams sisters until almost the end of the set, something no other team has done. Mattek-Sands and Yan went on to win the second set, but then the Venus and Serena Williams went up an early break in the third. When they were up 5-1, the match appeared to be almost over, but then Mattek-Sands and Yan won three games in a row. The Williams sisters were able to prevail, however, with a 6-4, 4-6, 6-4 score.
In other quarterfinal matches, top seeds Cara Black and Liezel Huber defeated Victoria Azarenka and Svetlana Kuznetsova 6-3, 6-3, and 6th seeds Lisa Raymond and Rennae Stubbs defeated 13th seeds Gisela Dulko and Flavia Pennetta 4-6, 6-2, 6-2.
