LONDON, England - No.2 seeds Sara Errani and Roberta Vinci find themselves in familiar territory, late in the stages of a Grand Slam, after fending off No.6 seeds Ashleigh Barty and Casey Dellacqua in doubles quarterfinal play at Wimbledon on Thursday.
Errani and Vinci made good on five of seven break points in their 6-4, 2-6, 6-0 victory over the Australians, who are three-time Grand Slam runners-up - including here last year.
Errani and Vinci are now 3-0 in their head-to-head with Barty and Dellacqua, having also beaten them in the 2013 Australian Open final and this year's French Open quarterfinals. Wimbledon is the only major that four-time Grand Slam champions Errani and Vinci have yet to capture.
A day after shocking No.1 seeds and defending champions Hsieh Su-Wei and Peng Shuai, Babos and Mladenovic converted on all six of their break points in their 6-3, 3-6, 6-4 defeat of Alla Kudryavtseva and Anastasia Rodionova.
Wednesday's action also saw Pektovic and Rybarikova win their quarterfinal encounter against 10th-seeded Julia Goerges and Anna-Lena Groenefeld, 6-1, 7-6(6). They are the only team left yet to drop a set this fortnight.
All of the duos except Errani and Vinci will be contesting their first Grand Slam semifinal. In fact, Hlavackova and Zheng are playing in just their second WTA-level event together, Babos and Mladenovic their third and Petkovic and Rybarikova their third.
