Leander Paes and Swiss Martina Hingis became the first team since 1969 to win three Grand Slam mixed doubles titles in the same season at the US Open on Friday.

The fourth seeds defeated American duo Sam Querrey and Bethanie Mattek-Sands 6-4, 3-6, 10-7 to add the New York crown to their wins at the Australian Open and Wimbledon.

The only other team to win three majors in the same year were Marty Riessen and Margaret Court 46 years ago.

The 42-year-old Paes now has won nine Grand Slam mixed doubles titles, against Bhupathi’s eight.

It was his 17th title in total at the majors while Hingis, 34, now has 19 from five singles, 10 women's doubles and four mixed.

Hingis can win another this weekend as she will team up with India's Sania Mirza in the women's doubles final against Casey Dellacqua and Yaroslava Shvedova.
