The superb run of New Zealand's Michael Venus and his American partner Ryan Harrison has ended in the semi-finals at the ATP Finals in London.
The French Open champions have been beaten in straight sets, 6-1, 6-4 by the world's number one ranked team, Lukasz Kubot and Marcelo Melo.
Venus and Harrison entered the semi-final at the O2 Arena unbeaten after three impressive wins in round robin and were full of confidence. They had beaten the Pole and Brazilian in the second round of the French Open on the way to their maiden Grand Slam title.
However Kubot and Melo served superbly throughout and dominated the match. They got off to a flying start, racing through the first set 6-1 with two breaks of serve, converting two of their five break point chances in the opening set.
Venus and Harrison did get two break points of their own but were unable to capitalise in the opener.
