Sania Mirza and her American partner Bethanie Mattek-Sands on Thursday reached the first final of the new season when their opponents -- Daniela Hantuchova and Katarina Srebotnik -- conceded the semifinal match at the WTA Brisbane International, in Brisbane.

The unseeded Indo-American pair was leading 5-1 in the opening set when Hantuchova found it unable to continue due to a groin injury.

Sania and Bethanie had shocked second seeded pair of Liezel Huber and Maria Jose Martinez Sanchez 6-2 6-3 in the second round of the $1000,000 event.
