When is the tournament?
The United Cup is an 18-team, mixed-team competition. The 11-day tournament begins on Dec. 29 and will be played across three cities, Sydney (Sydney Olympic Park Tennis Centre), Brisbane (Queensland Tennis Centre) and Perth (RAC Arena).
Teams in Sydney and Brisbane will play on outdoor hard courts. Perth will feature an indoor hard court. All three venues will use the Dunlop Australian Open balls.
What is the format?
The group stage will be played from Dec. 29 to Jan. 3. Each city will host two groups of three countries, competing in a round-robin format. Played over two days, ties will consist of two ATP and two WTA singles matches between the No.1-ranked players and No.2-ranked players and one mixed doubles match. If the tie is locked at 2-2 after singles, the mixed doubles match will decide the winner.
The winner of each of the two groups will advance to the City Final on Wednesday, Jan. 4 to determine which team will advance to the United Cup Final Four. The fourth team will be the City Final runner-up with the best record from its three matches.
The Final Four will have a travel day on Thursday, Jan. 5. The semifinals will be played across two days on Friday, Jan. 6 and Saturday, Jan. 7 in Sydney.
When is the final?
The United Cup final will be played on Sunday, Jan. 8 beginning at 1:00 p.m. in Sydney.
How have the groups been drawn?
Six countries qualified based on the ATP ranking of their No.1 player, six countries qualified based on the WTA ranking of their No.1 singles player and six countries qualified based on the best combined ranking of their No.1 ATP and WTA players. Australia received entry as the host nation.
The top six seeds are No.1 Greece, No.2 Poland, No.3 United States, No.4 Spain, No.5 Italy and No.6 France.
Who is playing and where?
The United Cup features a star-studded field that includes WTA World No.1 Iga Swiatek, reigning Australian Open champion Rafael Nadal, and WTA Finals champion Caroline Garcia. The all-star duo of Maria Sakkari and Stefanos Tsitsipas lead the top-seeded Greek squad, while World No.3 Jessica Pegula, Madison Keys and Taylor Fritz head up a strong United States team.
