NEW YORK (Reuters) - Top seeds Martina Hingis and Sania Mirza beat Casey Dellacqua and Yaroslava Shvedova 6-3 6-3 to win the U.S. Open doubles title on Sunday and cap off a perfect visit to Flushing Meadows.
Hingis, the Swiss former-world number one and her Indian partner Mirza, tore through the doubles tournament without dropping a set to claim back-to-back grand slams after their victory at Wimbledon.
It has been a productive and busy visit to New York for Hingis who also captured the U.S. Open mixed doubles title with India's Leander Paes.
Having only joined forces in March, Mirza and Hingis have enjoyed a successful partnership reaching six finals in 12 events and winning two majors.
After easily taking the first set Hingis and Mirza broke to open the second and apart from a late wobble were never really threatened by the Australian Dellacqua and Kazakhstan's Shvedova.
For Hingis it was her second U.S. Open doubles title coming 17-years after she won her first in 1998 with Jana Novotna.
