Marina Erakovic has advanced to the doubles quarter-finals at the French Open after a third round victory with partner Cara Black.
The duo beat Australian Sam Stosur and Italy's Francesca Schiavone 6-4, 7-5.
The defeat was Schiavone's second of the day after the 2010 singles champion lost in the third round to Victoria Azarenka 6-3, 6-0. Stosur was also knocked out of the singles yesterday.
Erakovic and Black will next face second seeds Andrea Hlavackova and Lucie Hradecka of the Czech Republic for a spot in the semi-finals.
The Kiwi and the Zimbabwean have proven a formidable partnership in recent months after reaching back-to-backs finals leading up to Roland Garros. They made both the Madrid Open and Internationaux de Strasbourg finals last month, the first time since 2008 that Erakovic reached a doubles final on clay.
