Indian tennis ace Sania Mirza and her partner Martina Hingis on Sunday lifted the US Open 2015 women's doubles title at the Flushing Meadows.
The top seeded Indo-Swiss pair beat Casey Dellacqua-Yaroslava Shvedova 6-3, 6-3.
Hingis, the Swiss former-world number one and Sania, 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 US 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 US Open doubles title coming 17-years after she won her first in 1998 with Jana Novotna.
Sania and Hingis took just less than an hour and half to outclass their Australian and Kazakhstan opponents.
The fourth-seeded pair were of no match to the top game displayed by Sania and Hingis as they sailed their way through yet another achievement.
Sania's ground-strokes from the back of the court and Hingis' agility at the net was too good for their rivals.
Sania now has five Grand Slam titles in her collection.
She won three Mixed Doubles trophies, the last one coming at this very venue with Bruno Soares in 2014.
In an extraordinary season, Hingis has won five Grand Slam titles this season, taking her overall number to 20. She won three titles with Paes and two with Sania.
"It's a great year for us. It's already been a great year for me. I became world number one. We were a solid team and were in with a chance in all Slams. We are happy to come through. I won mixed doubles here last year, great to come bak and win this," Sania said after her win and also thanked the Indians out there in stands who came out to support them.
An elated Hingis said,"from the start we hit it off. Our games complement each other. Sania won her first Wimbledon, for me it is bonus. I volley better than what I used to. (in her singles days)"
Shvedova committed a double fault in the second game at 30-all to give top seeds a break point and then a superb return from Sania brought another opportunity but the fourth seeds saved both chances.
The top seeds did not have to wait much for next chance as they broke Dellacqua at love to take a 3-1 lead. But the advantage slipped soon as Sania was broken in the fifth.
Shvedova, who is getting married on Tuesday, surrendered her serve one more time, letting Sania and Hingis just walk away with the set.
Shvedova was far from the player she is as she was down by three break points in the very first game of the second set. Top seeds grabbed the opportunity and consolidated lead with a solid hold.
Sania fired two stunning service winners on Dellacqua's serve as the Australian was broken at love in the seventh game. Hingis hit an overhead volley winner on the first match point after Shvedova's double fault at 40-all.
Last month, Sania, who is married to Pakistan cricketer Shoaib Malik, was honoured with the prestigious Rajiv Gandhi Khel Ratna Award - India's highest sporting honour.
