Peschke and Srebotnik, the No.2 seeds, arrived in Paris short of their very best form. However, judging by the early rounds, they are certainly finding their feet; they are yet to drop a set and produced their best performance of the week during a comprehensive 60 62 win over Renata Voracova and Klara Zakopalova.
Also advancing in the bottom half of the draw were No.3 seeds Vania King and Yaroslava Shvedova. Although the duo won two majors in 2011, Roland Garros is just their second tournament together this year - Shvedova has opted to play with fellow Kazakh Galina Voskoboeva in the lead up to the Olympics.
There has been no sign of rustiness in the first week, though, exemplified by their 64 62 third round triumph over Peng Shuai and Zheng Jie. Next up will be an intriguing last eight encounter with Maria Kirilenko and Nadia Petrova.
Meanwhile, in the top half, the Australian pairing of Jarmila Gajdosova and Anastasia Rodionova ended the run of Kaia Kanepi and Zhang Shuai.
Earlier in the week Kanepi and Zhang caused one of the upsets of the tournament as they stunned No.1 seeds Liezel Huber and Lisa Raymond in the first round. But on Sunday they finally ran out of gas, losing a tight two-setter to the No.14 seeds, 64 75.
