BEIJING, China - Top-seeded Kveta Peschke and Katarina Srebotnik and second-seeded Liezel Huber and Lisa Raymond were both pushed but advanced to the quarterfinals of the China Open on Tuesday.

Peschke and Srebotnik took on wildcards Karolina and Kristyna Pliskova three days after the 19-year-old Czech twins picked up their first WTA win together. After a surprising second set loss, Peschke and Srebotnik seized control early in the match tie-break en route to a 62 46 104 triumph.

As for Huber and Raymond, they took on Chan Yung-Jan and Lucie Hradecka, getting the first set's only break at 6-5 on Chan's serve and the second set's only break at 3-2 on Hradecka's serve in recording a 75 63 victory. Their win streak is now up to 11 matches and includes titles at the US Open and last week in Tokyo.

"Happy to get my first win in Beijing today. Third time's the charm, I guess," tweeted Raymond, who lost her opener here in 2008 alongside Chuang Chia-Jung and in 2009 with Rennae Stubbs.

Also moving on were No.7 seeds Peng Shuai and Zheng Jie, 62 63, over María José Martínez Sánchez and Klara Zakopalova. A seeded duo was beaten for the first time this week, with Raquel Kops-Jones and Abigail Spears upending No.6 seeds Iveta Benesova and Barbora Zahlavova Strycova, 61 64. It was not a huge shock, though, as the Americans had already defeated the Czechs once this year and have posted some impressive results recently, including a run to the final in Carlsbad in August and a title in Québec City in September.

The three teams still in contention for the two spots remaining in the draw for the TEB BNP Paribas WTA Championships - Gisela Dulko and Flavia Pennetta, Vania King and Yaroslava Shvedova and Victoria Azarenka and Maria Kirilenko - are all in action Wednesday.
