The ATP Cup is an international outdoor hard court men's tennis tournament between competing nations, which will premiere in January 2020. The tournament will be played across three Australian cities over ten days in the lead up to the Australian Open and will feature teams from 24 countries.
The Inaugural tournament is scheduled to take place between 3 and 12 January 2020, being played in Sydney, Brisbane and Perth. The finals of the competition will take place in Sydney between 2020 and 2022.
The teams that participate in the Cup are determined by the singles ranking of their best player. On the week after the US Open, 18 teams are announced, based on the best player singles ranking. For a country to qualify, it must have at least three players with ATP ranking, and two of them with singles ranking. The next six teams are announced the week of the ATP Finals. If the host didn't qualify on the first deadline of September, it will be awarded a wild card, leaving only five spots for the November deadline.
The tournament will feature the 24 teams divided in six groups of four teams each. The teams will face in ties composed of two singles match and one doubles match. The match between the No. 2 of each team will open the tie, then the No.1 of each team, and the doubles match closing the tie. The doubles match will be played regardless whether the tie is decided or not.
The winner team of each group will be joined by the two best second places in the quarterfinals of the tournament for consecutive knock-out rounds until a champion team is crowned.
