Green, who led by two strokes after each of the first two rounds, had a double-bogey seven on the 13th and bogeys at Nos. 14 and 15 to create a three-way tie for the lead. However, Green bounced back with a birdie on the 16th.
Australians Brett Rumford (68) and Gavin Coles (69), were tied for second. Adam Scott (69) was another shot back in fourth.
Green had only two bogeys in his opening two rounds, but lost four shots in three holes with his late collapse Saturday.
'I hit the ball pretty bad all day,' said Green. 'If I didn't have a putter and a sand iron, I would've been mid-80s. I had a good chance to put a good lead on and didn't execute that well.'
Scott said his round was 'mostly good.'
'The back nine is pretty tough in the wind in these conditions, and I thought I played pretty well,' Scott said.
Greg Norman, who needed a birdie putt on the 18th Friday to make the cut, shot a 68 and was tied for 23rd at 4 over. The highlight of his day came on the 393-yard, par-4 12th, when he holed his approach from 125 yards for an eagle.
'It was encouraging, solid,' Norman said. 'This is not an easy golf course.'
Norman said he didn't think he had a chance of catching the leaders.
'Back in my heyday if I was 10 (shots) back, I wouldn't be worried about it, I'd think I have a shot at it,' he said. 'I'm not in my heyday.'
