Singapore: Indo-Swiss pair of Martina Hingis and Sania Mirza played true to their No. 1 rankings as they beat Garbiñe Muguruza and Carla Suárez Navarro 6-0, 6-3 in the final of the BNP Paribas WTA Finals in Singapore for ninth title of the year.

The top seed pair is now unbeaten in 22 matches, stretching back six tournaments.

Mirza-Hingis broke Muguruza in the second game and there was no lokking back for the top seeds thereafter. They won the first set 6-0. The second set was more competitive, but there was to be no denying the Swiss-Indian duo, as they won it 6-3. The top seeds took just an hour and seven minutes to rout Spanish eighth seeds in the title clash.

This is the pair’s ninth title together this season, having also won in Beijing, Wuhan, Guangzhou, US Open (New York), Wimbledon (London), Charleston, Miami and Indian Wells. Their only loss in a final was at Rome.

Meanwhile, this is Martina’s 50th WTA doubles title, a milestone only 15 players have reached yet.
