New Zealand's top-ranked doubles player Michael Venus and his South African partner Raven Klaasen have just failed in their quest to reach the semi finals at the ATP World Tour Finals in London.
The sixth seeds have been beaten 6-3 7-6 (5) by the second-seeded Colombian pair of Robert Farah and Juan Sebastian Cabal in 1 hour 24.
The defeat ends Venus and Klaasen's impressive first season together in which they reached the Wimbledon final, won one title in Marseille in February but reached three other finals including their first ATP Masters 1000 final together in Toronto.
Venus and Klaasen got off to the worst possible start today after Venus held serve, Klaasen was broken in his opening service game and the Colombians served impeccably in the first set, dropping just three points on serve. Serving to stay in the set at 3-5 Venus was broken and Farah and Cabal clinched the opener 6-3.
