2023 United Cup

The 2023 United Cup was the first edition of the United Cup, an international outdoor hard court mixed-gender team tennis competition held by the Association of Tennis Professionals and the Women's Tennis Association. Serving as the opener for the 2023 ATP Tour and the 2023 WTA Tour, it was held from 29 December 2022 to 8 January 2023 at three venues in the Australian cities of Brisbane, Perth, and Sydney. It was also the first mixed-gender team event to offer both ATP rankings and WTA rankings points to its players: a player was able to win a maximum of 500 points.
Team United States defeated team Italy in the finals, 4–0, to capture the inaugural 2023 United Cup. Tem United States swept team Poland in the [|semifinals] while team Italy lost one match in their defeat of team Greece.

Format

Each city hosted two groups of three countries in a round robin format in the first week of the tournament. Each tie consisted of two men's and two women's singles matches, and one mixed doubles match. There was one men's singles and one women's singles match in each day or session, with the mixed doubles match taking place in the second day or in the evening session.
The group winners in each host city played off for one of three semi-final spots with the highest ranked host city playoff loser, taking into account all ties, becoming the fourth semi-finalist.
There was a travel day allocated before the semi-finals and final take place in Sydney.

Qualification

18 countries qualified as follows:

Six countries qualified based on the ATP ranking of their number one ranked singles player.
Six countries qualified based on the WTA ranking of their number one ranked singles player.
The final six countries qualified based on the combined ranking of their number one ranked ATP and WTA players.

In exchange for being the host nation, Australia was guaranteed one of the spots reserved for teams with the best combined ranking should they have failed to qualify on merit, though this was not needed as Australia qualified in the second combined ranking spot.
Teams featured three or four players from each tour.

Venues

Brisbane, Perth and Sydney each hosted two groups of three countries in a round robin format and the [|host city finals] in the first seven days of the tournament. Sydney hosted the semifinals and the final on the last four days of the tournament.
