The reigning French Open men's doubles champions are going their separate ways.
Michael Venus' partnership with American Ryan Harrison has come to an end, having won two tennis titles this year, highlighted by their success at Roland Garros in June.
Venus says he wants a playing partner who he can regularly practice with.
"You know, Ryan's top 50 in singles and that's his main priority, and he wants to continue to develop that, so it makes it tough to do both."
Michael Venus will next year partner South African Raven Klaasen, who's recently split with American Rajeev Ram.
Venus and Klaasen will start their partnership at the season-opening Brisbane International before playing at the ASB Classic in Auckland the following week.
Venus says Klaasen is a very athletic player and is quick around the net.
"I think our games will match up well, but it's one of those things, you don't really know until you try it."
