In individual doubles rankings, Sania is now only 145 points away from becoming World No 1.

Sania Mirza achieved yet another career milestone by capturing her 25th WTA doubles title as she partnered Martina Hingis to win the Miami Open title in Key Biscayne, Florida, on Sunday.

The top seeded Indo-Swiss pair overcame a sluggish start to beat the second-seeded pair of Ekaterina Makarova and Elena Vesnina 7-5, 6-1.

Sania and Hingis were trailing 2-5 in the opening set but regrouped and turned tables on their fierce opponents by reeling off eight games in a row.

Sania-Hingis had previously beaten the same Russian team to win their first title at Indian Wells.

It has been an absolute dream start for Sania and Hingis as they are yet to lose a set since they began their partnership.

"We just tried to keep telling each other to enjoy the struggle. Last week everything came very, very easily to us -- we didn't lose more than four games in a set. Over here we were down, and we were panicking. It was like, 'Oh my God, we're not playing well.' We just weren't used to that," Sania said after the match.

Hingis credited the win to tips provided by Sania's farther Imran Mirza during the match.

"Today the coaching really turned it around -- your dad came on court," Hingis said to Sania.

"The most important thing is that we never stopped believing we're a great team. They played a great set to get us to that position, 5-2 down. Then we just tried to stay in there and get our chances. We just built on every point, which is what we did well last week too," the Swiss great, who now has 43 doubles title, said.

With this win, Sania and Hingis now will move to number three from nine in the Road To Singapore doubles leaderboard.

In individual doubles rankings, Sania is now only 145 points away from becoming World No 1.
