Australian Masters:An out-of-sorts Tiger Woods battled to a share of the lead after the third round of the Australian Masters, as his rivals failed to capitalise on an off day for the world number one.

Woods held a three-stroke lead going into the third round and seemed set to charge ahead after draining a monster birdie putt on the par-four second. But that was almost as good as it got for the 14-times major champion, who said he felt lucky to escape with an even par 72.

Woods ended the day joint leader with local hopes Greg Chalmers and James Nitties on 10 under par at the co-sanctioned event. Jason Dufner and Cameron Percy are two shots further back.

"I was very fortunate, somehow I found a way to shoot even par today because it certainly should have been a lot worse than that," Woods told reporters at Kingston Heath Golf Club.

"I hit some really good shots out there as well but also I hit some just terrible golf shots and it was either-or, there was no grey area today."

After recovering to shoot a four-under 68 after a mid-round slump with the driver a day earlier, Woods's troubles were more prolonged on Saturday, the American finding bunkers on the sixth and eighth, and the fairway of the 10th when he was playing nine.

His frustration boiled over at one stage, his driver ending up in the hands of a spectator after Woods pounded it into the turf after a poor tee shot.

Woods said his troubles stemmed from a bad warm-up in the morning and his frustrations were compounded by some "atrocious" putting on surprisingly soft greens.

"I didn't hit the ball very good on the range and the golf course wasn't very good either," he said.

"As dry as (the greens) were yesterday, they were just really soft today, making ball marks, the balls were spinning back. It was a different golf course than we certainly would have thought."
