Michael Venus wins in Dubai, Artem Sitak into Sao Paulo semisGETTY IMAGES Michael Venus and Raven Klaasen are backing up last week's success in Marseille. It was close throughout and Venus and Klaasen relied on some clutch serving to win, saving seven of eight break points against them. Venus and Klaasen are on a five-match winning streak after initially taking some time to gel as a new team. Meanwhile, New Zealand doubles player Artem Sitak has continued his fine form by reaching the semifinals at the ATP 250 tournament in Sao Paulo. Sitak and Koolhof broke again at the start of the second set and went on to complete a comfortable win.
