Tennis - ATP Cup
An international outdoor hard court men's tournament which effectively took over the January slot in the calendar occupied by the Hopman Cup from 2020. However, it is played across three Australian cities (Sydney, Brisbane and Perth) over ten days and features teams from 24 countries split into six groups of four. The highest ranked players in each team play a singles match against each other, as do the other players in each side and then a doubles match rounds off each tie. The top two teams in each grpoup qualify for the quarter-finals.
