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

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

However, Sania lost 3-6, 4-6 after battling it out for over an hour against the Italian, who now leads the head-to-head record between the two players 3-2.

The loss ends Sania's campaign at the $ 4.5 million event as she has already been ousted from the doubles event after suffering a first-round defeat.

Paes and Dlouhy will take on another unseeded team of Argentines Juan Martin Del Potro [ Images ] and David Nalbandian [ Images ] in the second round.

Earlier in the tournament, the third seeded pair of Mahesh Bhupathi [ Images ] and Bahamas' Mark Knowles [ Images ] had edged past Russians Dmitry Tursunov [ Images ] and Igor Kunitsyn 7-5, 6-3 in their opening-round match.
