Coolum, Australia ? John Daly threw his putter and ball into the water near the 18th green. Then he shook hands with his playing partners and walked alone up the fairway to his villa on the course.

Daly was through for the afternoon — and for the tournament — after shooting a 78 Friday to complete a sad, frustrating few days at the Australian PGA.

Playing a week after his mother’s death, Daly was disqualified for failing to sign his scorecard following a second round in which Jarrod Moseley shot a 6-under-par 66 to take the lead.

Moseley had a 13-under 131 total and was a stroke ahead of two-time Australian Open champion Aaron Baddeley (65). Peter Lonard was two strokes back after a 68.

Daly was upset with an official’s ruling on the 13th hole and played the final six holes in 9 over. He refused to sign his scorecard, resulting in his disqualification.

This sort of display was all too familiar for Daly, who on top of his meltdowns on the course has battled problems with drinking, eating and gambling.

“It was vintage Daly, but I forgive him,” tournament promoter Tony Roosenberg said. “It’s been a very difficult week for him.”

At the 1997 U.S. Open, Daly walked off the course after the second round without telling his partners. In 1992, at the Australian Masters, he was disqualified after failing to sign a scorecard. A year earlier in Jamaica, he was disqualified for signing an incorrect card.

Andrew Langford-Jones, the tour’s operations director, said the tour would discuss a possible fine for Daly for not signing his scorecard and for his play on the 18th fairway where he played a drop from a hazard.

Daly was playing his third straight week in the Asia-Pacific region. He was to fly to the United States for the funeral on Monday of his mother, Lou, who died last week from cancer at 65.
