New Zealand's top ranked doubles player Michael Venus and his South African doubles partner Raven Klaasen have lost a tight final at the Japan Open ATP 500 tournament in Tokyo.
The world number 14 ranked Kiwi and Klaasen have been beaten by 4th seeds ex Kiwi Ben McLaughlin and German Jan Lennard Struff 6-4, 7-5 in 1 hour 22.
McLaughlin hails from Queenstown but has a Japanese mother and represents Japan. He was the defending champion in Tokyo.
McLaughlin and Struff won four of five deciding points in the match and weren't broken while Venus and Klaasen won three more points 63 to 60, but dropped serve once in each set. They will rue a failure to convert any of their five break point opportunities
Venus and Klaasen have now won just one of their five ATP finals this year, in Montpellier in February. Since then they have lost the finals at s-Hertogenbosch, Wimbledon, Toronto and now Tokyo.
Despite the defeat Venus and Klaasen have consolidated their place in the race to qualify for the season ending ATP World Tour Finals in London.
