Looking set for a straight sets victory are the top seeds, who dismantle the Czech pair in the first set, 6-3.

Hlavackova/Hradecka commit their first double fault! Hingis/Mirza have a solid 3-game lead in the first set. 4-1.

Under 10 minutes into the match, they're up 3-0 in the first set! Solid tennis from Mirza and Hingis.

The Indo-Swiss pair won back-to-back WTA titles in Guanghzou, Wuhan and Beijing and have been completely unstoppable since their US Open win.

The top seeded pair rose to World No. 1s earlier this year, and after multiple slam victories, they won back to back WTA tournaments as well.
