India's Rohan Bopanna and his doubles partner Florin Mergea booked their place in the World Tour Finals last four on Tuesday with a straight sets win at London's O2 Arena.

The eighth-ranked side beat home favourite Jamie Murray of Great Britain and Australia's John Peers 6-3, 7-6 (7/5), the fourth-ranked pairing, to secure a semi-finals spot.

Bopanna and his Romanian partner beat US identical twins Bob and Mike Bryan, the reigning champions, in their opening group game Sunday.

They have a third and final group game remaining against Italian partnership Simone Bolelli and Fabio Fognini before the semis.

"It's great to actually play with these guys and see the best guys playing in one of the best arenas, one of the best courts in the world," said Peers.

"It's actually a fantastic experience."
