Sania Mirza and Rohan Bopanna set up a mixed doubles quarter-final clash against each other at the Australian Open after winning their respective matches, in Melbourne.
Bopanna and his Canadian partner Gabriela Dabrowski knocked out the fifth-seeded team of Yung-Jan Chan and Lukasz Kubot 6-4, 5-7, 10-3 in their second round match.
Later, Sania and her partner Croatian Ivan Dodig, seeded second, overcame stiff resistance from Saisai Zheng and Alexander Peya to triumph 2-6, 6-3, 10-6.
Austrian Peya served a double fault at 5-5 in the decisive Super Tie-Breaker but after that the second seeds reeled off five straight points to seal the issue.
One Indian is now certain to feature in the semi-finals and if Leander Paes manages to win his quarter-final with partner Martina Hingis, the semi-final will again feature two Indians.
Paes and Hingis are up against local favourites Samantha Stosur and Sam Groth.
