Rohan Bopanna and Aisam-ul-haq Qureshi suffered their second defeat in the ATP World Tour Finals, beaten by second seeds Michael Llodra of France and Nenad Zimonjic of Serbia in Group A, in London, on Tuesday.
The fifth seed 'Indo-Pak Express' lost 6-7(6), 3-6.
Bopanna and Qureshi, who have just one match left to play in the group, committed as many as seven double faults compared to one by their opponents.
Both pairs won one of the two break-points they got in the first set, which went to the tie-breaker, where Llodra and Zimonjic cashed in on the mistakes of the Indo-Pak pair to nose ahead.
In the second set, the French-Serbian converted two of the five break-points they forced to snatch the set and match.
Bopanna and Qureshi, who lost to Max Mirnyi and Daniel Nestor on Sunday, dropped to a 38-25 season record, highlighted by three titles.
They played great tennis this year, winning three doubles ATP Tour titles -- at the Paris Masters, Stockholm Open and Gerry Weber Open. They also reached the semi-finals of the 2011 US Open before falling to Polish stars Marius Fyrstenberg and Marcin Matkowski in straight sets.
On Monday, Leander Paes and Mahesh Bhupathi suffered a 6-7(6), 1-6 defeat at the hands of Sweden's Robert Lindstedt and Horia Tecau of Romania in their first round Group A match.
The top two teams from the two groups make it to the semi-finals.
