The fifth seeded Indo-Zimbabwean pair defeated eighth seeded Czech-Chinese team 6-4 3-6 10-7 in an hour and 37 minutes in the semi-final of the USD 5,946,740 hard court event.
It will be first final of the 2014 season for Sania and Cara, who had won two back-to-back titles to end the previous season.
Before this event, in four tournaments this season, they twice suffered a first round exit and reached quarterfinals of the other two, including Australian Open.
They now await winners of the other semifinal between Su-Wei Hsieh/Shuai Peng and Svetlana Kuznetsova/Samantha Stosur.
