Sania Mirza and Rohan Bopanna won their respective doubles matches in contrasting styles to make it an all-win day for the Indians at the Australian Open here on Wednesday.

Sania and her Australian partner Alicia Molik, seeded sixth, won a two-hour battle against the unseeded Greco-German pair of Eleni Daniilidou and Jasmin Woehr 6-3, 4-6, 6-4 to advance to the second round.

In men’s doubles action, Bopanna teamed up with American-Indian Rajeev Ram to oust British-American duo of James Auckland and Sam Querrey 6-1, 7-6 (4).

Bopanna and Ram will next be up against the winners of the match between fifth-seeded Leander Paes and Paul Hanley and the unseeded pair of Luis Horna of Peru and Austrian Stefan Koubek.

Sania and Molik will take on Russians Nadia Petrova and Elena Vesnina, who breezed past local favourites Sophie Ferguson and Trudi Musgrave 6-3, 6-4.

The sixth seeds had no trouble in pocketing the opening set in just over half an hour, capitalising on their opponents poor serve and several unforced errors.

However, Sania and Molik were in for a shock in the second set as Daniilidou and Woehr broke them twice in the 40-minute contest to draw even and take the match into a third set.

The decider was also an even battle but Sania and Molik came out trumps after breaking their rivals thrice out of the six chances they got besides being slightly ahead in the overall winners tally.

In contrast, Bopanna and Ram were in fine form as they held serve and broke Auckland and Querrey twice to take the opening set in just 25 minutes.

The second set was a bit more testing but the Bopanna and Ram came through after their opponents failed to convert their chances.
