Australian John Peers and New Zealander Michael Venus have become the sixth doubles team to qualify for the ATP Finals in London.
The Oceanian pair beat Austin Krajicek and Franko Skugor 6-4 7-6 (7-4) on Thursday to reach the Paris Masters quarter-finals.
After Sander Gille and Joran Vliegen's loss later in the day, the pair's place in the London showpiece was clinched.
Peers and Venus have enjoyed an excellent season, winning three ATP Tour titles - Dubai in February, the Hamburg European Open in September and the European Open in Antwerp in October.
Peers and Venus join Rajeev Ram and Joe Salisbury, Mate Pavic and Bruno Soares, Kevin Krawietz and Andreas Mies, Marcel Granollers and Horacio Zeballos and Wesley Koolhof and Nikola Mektic in London.
It gives 32-year-old Peers the chance to add to the ATP Final triumphs he enjoyed in 2016 and 2017 with Finland's Henri Kontinen, while Venus has the opportunity of winning his first after finishing runner-up with South African Raven Klaasen at last year's season finale.
