Swiss veteran Martina Hingis and India’s Sania Mirza won the WTA Finals doubles title on Sunday with a lopsided 6-0, 6-3 win over Spain’s Garbine Muguruza and Carla Suarez Navarro. Hingis and Mirza, who formed their partnership only in March, have now won nine titles including Wimbledon and the US Open, and swept all their matches at the season finale in Singapore. The top seeds took just 66 minutes to beat the Spaniards, who were seeded eighth.
