Australian selectors revealed on Monday that Test and one-day skipper Pat Cummins has a fractured wrist but should be fit for the World Cup as they also named an initial 18-man squad for the 2023 World Cup.
Marnus Labuschagne was a glaring omission, with Hardie and promising young spinner Tanveer Sangha included. The squad will be the same for the preceding five-match one-day series against South Africa.
Marsh will take the armband for the first three T20 matches since Aaron Finch's retirement. The World Cup squad will be slimmed down to 15 in early September.
Australia’s preliminary World Cup squad: Pat Cummins (capt), Sean Abbott, Ashton Agar, Alex Carey, Nathan Ellis, Cameron Green, Aaron Hardie, Josh Hazlewood, Travis Head, Josh Inglis, Mitchell Marsh, Glenn Maxwell, Tanveer Sangha, Steve Smith, Mitchell Starc, Marcus Stoinis, David Warner and Adam Zampa.
