Leander Paes advanced in men's doubles but it was curtains for Sania Mirza who crashed out of the women's singles event after a straight-set loss to 12th seed Italian Flavia Pennetta in the second round of the BNP Paribas Open here today.

Fourth seeds Paes and his Czech partner Lukas Dlouhy carved out a hard-fought 6-4, 3-6, 10-8 win over unseeded Austrians Julian Knowle and Jurgen Melzer in the opening round.
