NEW YORK, NY, USA - Just like in their first round doubles match, Serena and Venus Williams were pushed in the first set and just like in their opener, they eventually cruised to victory on Friday.
The Williamses recorded the exact same scoreline, 64 60, in beating No.15 seeds Klaudia Jans-Ignacik and Kristina Mladenovic as they did against Lindsay Lee-Waters and Megan Moulton-Levy two days prior. The serve proved the difference, as they never faced a break point and won 25 of 29 first serve points in advancing to the third round.
The reigning Wimbledon and Olympic champions are now 13-0 on the year, 20-2 all-time at the US Open and 104-8 at majors. They are seeking their 14th Grand Slam title, which would tie them with Gigi Fernández and Natasha Zvereva for second-most by a team in the Open Era.
Also advancing were No.1 seeds and defending champs Liezel Huber and Lisa Raymond, 62 75, over Jarmila Gajdosova and Alicja Rosolska. Huber, who has played in four straight finals here with wins in two of them, has now been victorious in 24 of her past 26 matches at Flushing Meadows.
Second-seeded Italians Sara Errani and Roberta Vinci posted a routine 64 62 triumph over Jill Craybas and Chanelle Scheepers. They now have 48 wins in 2012, one more than Huber and Raymond for most on the WTA.
No.5 seeds Vania King and Yaroslava Shvedova rallied from a 4-1 third set deficit in their 67(1) 76(4) 64 thriller over Nina Bratchikova and Alexandra Panova. The 2010 US Open titlists and 2011 runners-up improved to 13-1 here and 29-5 in Grand Slam play.
Other seeds advancing were sixth-seeded Russians Ekaterina Makarova and Elena Vesnina, ninth-seeded Americans Raquel Kops-Jones and Abigail Spears, 11th-seeded Julia Goerges and Kveta Peschke and 16th-seeded Hsieh Su-Wei and Anabel Medina Garrigues.
Iveta Benesova and Barbora Zahlavova Strycova and Anastasia Rodionova and Galina Voskoboeva joined Klaudia Jans-Ignacik and Kristina Mladenovic as seeds sent to the sidelines. The 10th-seeded Benesova and Zahlavova Strycova were defeated by Angelique Kerber and Tamira Paszek, and the 12th-seeded Rodionova and Voskoboeva mustered just three games versus Sabine Lisicki and Peng Shuai. The German-Chinese duo has only surrendered six games through two matches - fewest of those who are into the third round.
In mixed doubles action, Kim Clijsters kept her last US Open campaign alive by partnering Bob Bryan for a first round win. Also, No.1 seeds Huber and Max Mirnyi moved on, but No.2 seeds Raymond and Mike Bryan were upset.
