Sania Mirza and her partner Chuang Chia-jung of Taiwan rallied to stun eighth seeds Maria Kirilenko and Flavia Pennetta in a gruelling three-setter for a place in the women's doubles quarter-final of the $4.5 million Miami Masters.

Sania and Chuang shocked the fancied Russian-Italian pair 4-6, 7-6 (5), 10-4 to enter the last-eight stage. The unseeded Indo-Taiwanese duo will next take on the winners of the match between the Argentine-Israeli team of Gisela Dulko and Shahar Peer and the Spanish combine of Anabel Medina Garrigues and Ruano Pascual.
