Third seeds Sania Mirza and Shahar Peer survived a scare from Tatiana Poutchek and Anastasia Rodionova before advancing to the doubles quarter-finals of the US $600,000 Bank of West Classic tournament in Stanford.
The Indo-Israeli pair beat the unseeded Belarussian-Russian duo 6-1, 0-6, 11-9 in over an hour at the WTA Tour hard court tournament on Wednesday.
Sania and Peer will meet the Uzbek-German team of Akgul Amanmuradova and Angalika Bachmann.
Sania, who is aiming for a second successive doubles title after her triumph in Cincinatti with Bethanie Mattek last week, and Peer failed to convert two breakpoints in the third set which saw them being broken thrice.
But they got their act together in the super tie-breaker to advance to the quarters.
