The dream run has continued for Kiwi tennis player Michael Venus at his maiden ATP Tour Finals in London.

After seeing off the defending champions, Venus and his American doubles partner Ryan Harrison have clinched a spot in the semi-finals.

They smashed Finland's Henri Kontinen and Australian John Peers first up in straight sets - now Venus and Harrison have posted a comeback super tiebreak win over higher-ranked French pair Nicolas Mahut and Pierre-Hugues Herbert.

After dropping the first set to the sixth seeds in a tiebreak, they won the second 6-4 - then thrashed the Frenchmen 10-5 in the super tiebreak.

"We had a bit of momentum going after that second set," Venus told Newshub.

"Super tiebreakers, anything can happen and we took care of our service points and got a hold of some returns and got up early and managed to keep that momentum going and just ran away with it a little bit."

The New Zealand-US combination won the French Open back in June - and while Venus would love to add the season-ending showpiece to his breakout year, the 30 year old isn't looking beyond his next match.

"That would kind of be a dream come true for the year I've had, to be able to finish on a high like that," he said.

"But one match at a time, one point at a time - there's a long way to go and lots of things that we need to take care of and put ourselves in a position to hopefully be there at the end of the tournament."

Venus and Harrison play Dutchman Jean-Julien Roger and Horia Tecau of Romania in their final pool match before the playoffs.
