Australia will hope Mitchell Starc does not need to be at his best on day three of the third Test against Sri Lanka, with the bowler planning an early start to cheer on his Olympian sibling from afar.
Brandon Starc will make his Olympic debut in men's high jump qualifying in Rio on Sunday.
Australia are 141-1 in their first innings, chasing Sri Lanka's 355, in the dead rubber in Colombo, the tourists having already gone 2-0 down to lose the series.
Mitchell Starc is due to bat at number eight, meaning the 26-year-old will not be called upon early on Monday unless the visitors, who have struggled against spin on the subcontinent, suffer another collapse at the Sinhalese Sports Club Ground.
"I'm glad we're batting so I'll be able to get up about 5am and watch the brother over in Rio do his thing in the high jump," he said.
"Pretty excited and proud of the younger brother to represent his country at an Olympics. He sounds pretty excited as you would be in your first Olympic Games.
"He's worked his butt off to get there, so I'm very proud of him, and I'm sure he'll do himself and his country proud."
Brandon Starc finished 12th in the high jump at the 2015 World Championships in Beijing.
