The new year begins with the outdoor hard court United Cup being played in Australia. Greece takes on debutants Japan in Group E which also includes Great Britain. Can the resurgent Naomi Osaka get Japan off to a good start with a victory over Maria Sakkari? Read our match prediction below.
The tournament is being played in Perth and Sydney. This group is being staged in Perth and the group winners will qualify for the last eight but there's also a place for the best runner-up in each city.
Naomi Osaka is up to 16th in the world rankings after beginning 2025 down at 57th. Last year ended with her making it to the quarter-finals in Osaka but then withdrawing. The 28-year-old will hope for an injury free 2026.
One tournament was won by Osaka last year but that was played on clay.
Maria Sakkari has only won two of her five previous matches against Osaka. The 30-year-old began last year ranked 32nd but is down to 52nd last year. Both of her matches in the 2025 United Cup were lost as Greece failed to make it out of the group stage.
The former top ten player ended 2025 poorly with just one main draw win in her last four tournaments.
We tip more than 19.5 games to be played.
