2nd seeds Liezel Huber and Nadia Petrova advanced to the U.S. Open semifinals today, with a 6-4, 3-6, 7-5 win over 5th seeds Lisa Raymond and Rennae Stubbs. Also advancing were 7th seeds Chan Yung-Jan and Zheng Jie. They defeated Bethanie Mattek-Sands and Meghann Shaugnessy 6-4, 6-4.
These U.S. Open doubles matches are quite entertaining. It's a shame so little attention is paid to them.
