Mirza and Zheng fell behind an early break but quickly got back and from 3-3 in the first set, they won six of the next seven games to capture the first set and take control of the second.
They did have a bit of trouble closing it out, as at 5-2 in the second set, Medina and Srebotnik won two games in a row and then got to deuce on Mirza's serve before the Indo-Chinese duo finished off the triumph on their fifth match point.
"We didn't start the tournament too well, winning a couple of what you might call ugly matches. But we kept getting better with each match. It was great to play our best match in the final," Mirza said.
"It's tough with this format. It's relentless. There's really no margin of error with the deuce points, the super tie-break. It's just a toss-up sometimes. Even today's match was 63 64, but it was much tighter with the deuce points. The last set we won three deuce games," she said. It was Sania's fourth final of the year and 25th 0overall.
Sania, the only Indian woman to win a Grand Slam title, had won two titles this season before this triumph. Both the previous titles came with American partner Bethanie Mattek-Sands.
