PARIS, France - A few hours after she scored her first Top 5 win in singles to advance to the Roland Garros semifinals on Tuesday, Sara Errani secured a place in the doubles quarterfinals alongside fellow Italian Roberta Vinci.

Errani and Vinci's 63 61 defeat of Janette Husarova and Sabine Lisicki took just over an hour, which surely was a relief to Errani after a tough two-setter in singles against Agnieszka Radwanska. The third round triumph was Errani and Vinci's ninth straight win here, and 2012 French Open singles runner-up and doubles champion Errani has now won 20 of her last 21 singles and doubles matches here. Next up for the No.1 seeds are Varvara Lepchenko and Zheng Saisai.

Also booking a quarterfinal berth were 10th-seeded Kristina Mladenovic and Galina Voskoboeva, who had the most lopsided scoreline of the day, 61 61, over Oksana Kalashnikova and Alicja Rosolska. The French-Kazakh duo won 21 out of their 24 first serve points and saved the one break point against them in the 57-minute rout. Next up for them are fourth-seeded Ekaterina Makarova and Elena Vesnina, whom they beat handily in the quarterfinals of Madrid last month in their best win to date in terms of ranking.

No.11 seeds Anastasia Pavlyuchenkova and Lucie Safarova also advanced to Wednesday's quarterfinals, albeit in less satisfying style over Bethanie Mattek-Sands and Sania Mirza - who retired down a set but up a break because of a right thigh injury suffered by Mattek-Sands. Awaiting the Russian-Czech pairing are No.3 seeds Nadia Petrova and Katarina Srebotnik.

In mixed doubles action, Liezel Huber and Marcelo Melo reached the quarterfinals, where they will take on Lisa Raymond and Bruno Soares. Interestingly enough, Huber has won 10 WTA titles with Raymond, including the 2011 US Open and WTA Championships. And Melo and Soares have won four ATP World Tour titles together. On top of that, Soares just defeated Melo in men's doubles third round play on Tuesday.
