Alex de Minaur led Australia to the ATP Cup semi-finals in 2020 and the young Aussie will return to the team competition this year. The 21-year-old will carry the hopes of the home nation alongside Australian No. 2 John Millman.
Millman, who captured his maiden ATP Tour title in Nur-Sultan last year, will also be making his second appearance in the competition. De Minaur and Millman are joined by doubles stars John Peers, career-high of No. 2 in the FedEx ATP Doubles Rankings, and 2020 Australian Open finalist Luke Saville (w/Purcell).
