New Zealand's Michael Venus and American doubles partner Ryan Harrison have made a stunning start to the ATP Finals in London.
The 8th seeded team have beaten the defending champions, Finland's Henri Kontinen and Australian John Peers 6-4, 7- 6 (8-6) in their opening round robin match.
"It was a great match and we created a lot of opportunities returning serve. We didn't capitalise early on but we kept on playing well and got there in the end," Venus said.
Played in front of 17,000 spectators at London's O2 Arena, Venus and Harrison who are making their debut at the season ending championships were far from overawed.
"Walking out there it was very cool but we just enjoyed the whole moment and occasion and we just have to keep doing that throughout the tournament," Venus said.
