Miami (USA): Indian tennis star Sania Mirza and her Czech partner Barbora Strycova were stunned by unseeded giantkillers Gabriela Dabrowski of Canada and Xu Yifan from China in the women's doubles summit clash of the Miami Open in Miami.

Sania and Strycova, aiming for their third title together, lost 4-6 3-6 in a match that lasted little over an hour.

Before this tournament, she and Dabrowski had never been on the same court for a match -- as partners or opponents -- but practiced together at the BNP Paribas Open.

Prior to the final, Dabrowski and Yifan had knocked out eighth seeds Abigail Spears and Katarina Srebotnik besides upsetting three of the top-four seeds in succession.
