Australia's Ashleigh Barty and Casey Dellacqua have been dumped out of the French Open quarterfinals in straight sets by second-seeded Italians Sara Errani and Roberta Vinci.

The seventh-seeded Australians had high hopes of reaching the semifinals but were routed 6-0, 6-1 on Tuesday.

Errani and Vinci go on to face unseeded pair Lucie Hradecka and Michaella Krajicek or New Zealand's Marina Erakovic and Spaniard Arantxa Parra Santonja, who play their quarterfinal on Wednesday.

The top seeds, Su-Wei Hsieh of Taiwan and Peng Shuai of China, recovered from a rocky second set to beat Zimbabwe's Cara Black and India's Sania Mirza 6-2, 3-6, 6-3.
