MADRID, Spain - Sara Errani and Roberta Vinci continued their recent strong form with a routine defeat of Svetlana Kuznetsova and Samantha Stosur on Wednesday to secure a quarterfinal berth at the Mutua Madrid Open.
After capturing their fourth Grand Slam title at January's Australian Open, Errani and Vinci went through a bit of a drought by their standards by not reaching a final for five straight events. But then at their last tournament in Stuttgart, the leaders on the Road To Singapore leaderboard did not surrender more than three games in a set en route to the title.
Errani and Vinci posted another dominant scoreline against Kuznetsova and Stosur, 6-3, 6-1, avenging a loss to the Russian-Australian duo in their Indian Wells opener in March. Kuznetsova lost a tight three-setter to Agnieszka Radwanska in singles earlier in the day. The second-seeded Italians, who won the title here in 2012, next take on Vania King and Zheng Jie.
No.1 seeds Hsieh Su-Wei and Peng Shuai, who had fallen in their opener in their last two events and who lost in the first round here last year, got back on the winning track with a 6-4, 6-1 victory over Francesca Schiavone and Sílvia Soler-Espinosa.
Hsieh and Peng's quarterfinal opponents will be fifth-seeded Cara Black and Sania Mirza, who converted on six of seven break point opportunities in their 6-4, 6-1 triumph over Chan Hao-Ching and Chanelle Scheepers - their 15th win in their past 18 matches.
"We got the win last week in Portugal, so we're getting matches under our belt," Black said. "We had a tough match today, tough opponents. We're happy we came out and played really well. We're looking forward to the next match."
"We had to adapt to the conditions pretty quickly because we just got here on Sunday, but it's been good," Mirza said. "Today was a much better match than yesterday. And hopefully we can keep getting better as the tournament progresses."
Also advancing by a 6-4, 6-1 score were sixth-seeded Americans Raquel Kops-Jones and Abigail Spears, who overcame a 3-0, two-break deficit in the first set against Klara Koukalova and Monica Niculescu. Their quarterfinal opponents, Garbiñe Muguruza and Carla Suárez Navarro, were 7-5, 6-2 upset winners over fourth-seeded Kveta Peschke and Katarina Srebotnik.
