Last year the Kiwi playing with American Ryan Harrison won all three round robin matches before losing in the semi finals.

The top two teams in each group advance to the semi finals.

Oliver Marach and Mate Pavic, who have clinched the year-end No. 1 ATP Doubles Team Ranking lead Group Knowles/Nestor.

Henri Kontinen and John Peers, winners of the ATP Finals title for the past two years, will serve as doubles alternates at the season finale.

It's a lucrative end to the season for Venus who has so far earned $543,000 US dollars in prize money after reaching the Wimbledon final and final of the Toronto Masters 1000 tournament. Each pair earn $100,000 USD as an appearance fee in London with $38,000 US for each round robin win. A semi final match win would earn $103,000USD and winning the final $200,000.

Going through the tournament unbeaten would earn the pair $517,000 USD.
