India's Leander Paes and the Czech Republic's Lukas Dlouhy are out of the ATP World Tour Finals doubles with a straight set loss to American Bryan brothers, Bob and Mike.

Paes and Dlouhy went down 3-6, 4-6 in a Group B match here Wednesday evening.

The Bryans broke the Indo-Czech pair's serve twice in the 84-minute match and won 78 per cent of points on serve.

Paes and Dlouhy had lost their first match to Lukasz Kubot and Oliver Marach and do not have a chance to qualify for the semi-finals.

'It was bit of a rough outing in the last two matches,' Paes said. 'Its a bit strange because we won two Grand Slams this year and the last two days we've been pretty much off rhythm. Could put it down to many reasons. But, at the end of the day it's something we need to look at in the drawing board.'

The Bryan brothers are well poised to finish the year on No.1 ranking, with rivals Daniel Nestor and Nenad Zimonjic's defeat Tuesday evening.

The Americans will be crowned the top doubles team if they win their remaining matches and claim the title.
