According to a report in Brisbane Times and Sydney Morning Herald, Cummins believes Marsh can still change red-ball games, pointing to his impact at Headingley during the 2023 Ashes.
Marsh has made scores of 36, 53, eight, 60 and 84 from five ODIs in South Africa, showing quick-scoring touch. He is expected to play in the final ODI in Johannesburg, starting 9:30pm AEST Wednesday.
His potential return to Test colours would raise eyebrows, given his last Test appearance was December 2024 and Australian cricket faces mounting pressure to rejuvenate its ageing roster. However, there is a view within the team that a brutal calendar of Test matches against tough opponents in challenging locations is not the time to be experimenting with youth.
If recalled, Marsh could fill the No.3 position currently occupied by Marnus Labuschagne, or take on a middle-order enforcer role similar to the one Travis Head gave up to move to the top of the order last summer.
Marsh retired from first-class cricket for Western Australia last summer but has pointedly not retired from Tests, leaving the door ajar for a return.
