Rogers Cup: Sania-Hingis stunned by unseeded American duo in quarters

Top seeded pair of Sania Mirza and Martina Hingis crashed out of the Rogers Cup after going down to Christina Mchale and Asia Muhammad in the quarterfinals of the women's doubles event here on Saturday.

The Indo-Swiss pair were far from their best as they were beaten 4-6, 3-6 by the unseeded American duo in a match that lasted 70 minutes.

Both Mirza and Hingis will take part in next month's Rio Olympics, where the former will partner India's Rohan Bopanna and Prarthana Thombare in the mixed doubles and women's doubles respectively.

Mirza and Hingis have had a mixed run so far this year as they won their last tournament at the Italian Open in May. Although the pair won the Australian Open this year, they crashed out of the French Open and Wimbledon in the third and quarterfinal rounds respectively.

Mirza and Hingis had been in sublime form last year and extended their winning streak to 41 this year before losing at the Qatar Open in February.
