Barring injury New Zealand's top ranked doubles player Michael Venus will play at the ATP World Tour Finals in London next month.
Tour officials at the Shanghai Masters have confirmed while the top seven ranked teams on the Emirates ATP rankings after this month's regular season finale in Paris qualify for the O2 Arena, one place is reserved for a Grand Slam champion not in the top seven.
Venus and partner Ryan Harrison are currently ranked seventh in the race, but even if they fail to win another match, are guaranteed their place in the prestigious field.
That's because they are the French Open champions and the other three grand slam winning teams this year have already qualified for the World Tour Finals, in the top three in the rankings.
The ATP tour saves a place for a team who are Grand Slam champions as long as they are ranked between 8 and 20 after Paris. There's no way Venus and Harrison can slip outside the world's top 20 teams with only a handful of tournaments remaining in the season.
