Sania Mirza had a rollercoaster day at the US Open as she advanced to the quarterfinals of women's doubles with an upset win over former champions Lisa Raymond and Samantha Stosur but crashed out of the mixed event after a straight-set loss in the last-eight stage in New York.
Sania and her American partner Bethanie Mattek rallied to shock the second seeded American-Australian pair 2-6, 7-5, 7-5 on Monday.
The 16th-seeded Indo-American duo will next take on fifth seeds Yung-Jan Chan and Chia-Jung Chuang of Chinese Taipei for a place in the semifinals.
However, the 20-year-old Hyderabadi's campaign came to a halt in the mixed doubles event. Sania and Mahesh Bhupathi were outplayed 4-6, 1-6 by the Belarusian pair of Victoria Azarenka and Max Mirnyi.
But Leander Paes made sure that the Indian challenge continued in the mixed competition. Paes and his American teammate Meghann Shaughnessy beat local favourites Ashley Harkeroad and Justin Gimelstob 6-3, 6-4 to advance to the semifinals.
They will now be up against the British-American pair of Jamie Murray and Liezel Huber, who defeated Poland's Agnieszka Radwanska and Mariusz Fyrstenberg 6-1, 6-2.
