Casper Ruud has been runner-up at the US Open and twice at the French Open
Norway's Casper Ruud says he "probably won't be here the next day" if his wife goes into labour during the Australian Open.
Maria is heavily pregnant with their first child, a daughter.
Ruud, the 12th seed, beat Italy's Mattia Bellucci 6-1 6-2 6-4 in the first round in Melbourne on Monday.
"I have to thank Maria for letting me go in the first place. I know she's at home resting, getting ready," he said.
