Britain's Jamie Murray and Brazilian Bruno Soares have secured qualification for the ATP World Tour Finals doubles event at the 02 in London in November.
The pair ensured their place by winning their third-round match at the US Open against Brian Baker and Marcus Daniell 6-3 7-6 (9-7).
This year's event runs from 13-20 November.
But the pair won the Sydney International before the Australian Open and also reached ATP Tour finals in Monte Carlo and Toronto.
Murray, 30, will be making his second consecutive London appearance.
Last year, he and partner John Peers were eliminated in the group stage.
The tournament sees the top eight ranked pairings split into two groups with the top two from each pool making the semi-finals.
