Sania Mirza and Bethanie Mattek set up a quarter-final clash with American sisters Venus and Serena Williams after getting past the Uzbek-Belarussian pair of Akgul Amanmuradova and Darya Kustova in the third round of Wimbledon Championships in London.
The 13th seeded Indian-American pair was leading 4-6, 6-4, 2-0 when their opponents forfeited the match.
The Williams, seeded 11th and both of whom are already in the singles quarters, swept aside the fifth seeded Spanish pair of Anabel Medina Garrigues and Virginia Ruano Pascul 6-1, 6-4 in their third round match.
With Monday's win, Sania has reached Wimbledon doubles quarters for the first time.
The best that she had managed before this win was a third-round appearance last year, when she had teamed up with Israeli Sahar Peer.
