Sydney: At one stage seemingly set to lose the final, Sania Mirza and Martina Hingis came up with a stupendous performance to earn a fantastic come-from-behind victory and clinch the Sydney International title at the Ken Rosewall Arena on Friday.

The top seeds were down and almost out when they were trailing 1-6, 2-5 against French third seeds Caroline Garcia and Kristina Mladenovic. But the Indo-Swiss combine staged a remarkable come-back to eventually win the second set 7-5 and the super tie-break 10-5 in an hour and 14 minutes at the NWS Tennis Centre.
