In the super tie-break, Sania and Bethanie were down initially before scoring six points in a row and emerging as deserving winner with 10-7.
Sania and Bethanie, however, sealed the match in their favour by winning the crucial tie-breaker.
A visibly delighted Sania the match said, "We were just trying to attack more when we lost the second set. When we went down 4-Love, I think we went a little passive and defensive. When you play people like Nadia and Kata, you have to be offensive."
