Australia has an honorary co-captain for its Boxing Day test - seven-year-old Archie Schiller, who has put his congenital heart battles aside for an amazing time at the Melbourne Cricket Ground.
Just a year ago, Archie was breathing through a tube in a hospital bed after his third heart operation. But on Wednesday, he joined the Australian test team on the MCG as they took on India.
Thousands of cricket fans watched as he received his baggy green cap from off-spinner Nathan Lyon and he also shook hands with the Indian captain Virat Kohli at the coin toss.
And when he was asked on the match broadcast what his advice to the Australian team was, he replied: "Hit sixes and get wickets".Archie was his granted his dream to "to captain Australia" by Cricket Australia and the Make-A-Wish Foundation charity. Archie was diagnosed with a heart condition at birth and underwent open-heart surgery at three months and he has undergone 13 surgeries in total.
