Ellie Day – who is expecting their fifth child in early September – wants her husband to remain at East Lake Country Club in Atlanta this weekend if she goes into labour instead of returning home to Ohio.

"She said, 'You're not likely to make it back in time if I do go into labour'," Day told a U.S golf publication.

"We're having a home birth. She said I may as well just play the tournament and try to win."

The 35-year-old Queenslander missed the 2012 Open Championship with the arrival of his first-born son, Dash.

"I'm just hoping that Ellie holds out another week or two weeks and I can be there and spend some time with my family," Day, who finished joint-second in the recent Open Championship at Hoylake, said.

"I think if this was my first (child), I'd be a little bit more nervous about it."

Under the FedExCup finale scoring system, Day, a 13-time PGA Tour winner who ended a five-year drought in May by capturing first place at the AT&T Byron Nelson, will start nine shots behind Scottie Scheffler heading into action in Atlanta.
