The Indian challenge at the BNP Paribas Open ended after Leander Paes [ Images ] and Mahesh Bhupathi [ Images ] lost their respective second-round doubles matches at the US $4.5 million tennis tournament in Indian Wells.

Paes and his Czech partner Lukas Dlouhy [ Images ], seeded fourth, went down 6-7 (6), 6-7 (5) to Argentines Juan Martin Del Potro [ Images ] and David Nalbandian [ Images ].

In another match, the third seeded pair of Bhupathi and Bahamian Mark Knowles [ Images ] were stunned 6-7 (2), 4-6 by the unseeded Israeli-Belarussian duo of Max Mirnyi [ Images ] and Andy Ram [ Images ].

The twin losses rounded off a disappointing Indian campaign at the hard-court event, where Sania Mirza [ Images ] couldn't go past the second round in women's singles and crashed out of doubles in the first round itself.
