SYDNEY — John Daly hit seven balls into the water on the 11th hole and stormed off the golf course at the Australian Open. Already with a tarnished reputation Down Under, he might have gone too far with Australia’s golf hierarchy.

Daly was banned from playing in the Australian PGA in two weeks.

And he might not be welcome back.

“It’s very disappointing for the tournament ... that he has treated the championship this way,” Trevor Herden, Golf Australia’s director of tournaments, said Thursday. “It is a bit of a habit.”

Daly was 7 over after 10 holes in the first round after becoming upset on the 10th hole when he hit a practice ball out of a bunker, believing it was his tee shot. The two-shot penalty and a three-putt that followed gave him a triple bogey.

On the 11th, he hit ball after ball into the water, some landing in the center of the pond, before a tour official joined him. Moments later, Daly shook hands with playing partners Craig Parry of Australia and American Hunter Mahan and walked off the course.

He would have been hitting his 16th shot if he had more golf balls.

“Once I saw two go in, I think the effort went down pretty fast,” Mahan said. “It doesn’t do anyone any good for John to do what he did. It’s unfortunate, J.D. is a pleasant guy.”

Parry was mostly sympathetic towards Daly, saying he had the right club to reach the green, but the wind was stronger than Daly realized.

“I like John, he’s a great guy,” Parry said.

Daly said on Twitter, “when u run out of balls u run out of balls. yes, I shook my player’s partners hands & signed my card w/rules official.”

In a text message to The Associated Press, Daly said he hasn’t had confidence in his game since he was injured five years ago.
