Allenby booed, jeered upon return to golf after Hawaiian mystery

Robert Allenby has battled headaches and a few boos on the notorious Phoenix Open party hole in his first round since his mysterious misadventure in Hawaii.

Two days after saying he was preparing mentally for one of the toughest weeks of his life, the Australian carded a one-under 70 to be tied for 42nd, six shots from the lead.

Ryan Palmer sits alone at seven-under 64, one stroke ahead of fellow Americans Keegan Bradley, Bubba Watson and Daniel Berger.

Allenby drew only a few boos and comments on the rowdy par-3 16th stadium hole and the crowded 18th, enjoying mostly quiet, apathetic galleries.

On Tuesday, the 43-year-old stood by his story that he was robbed and beaten after missing the cut two weeks ago in the Sony Open, basing the account on what he remembered and what he was told by a homeless woman who came to his aid.

He said he has "no memory" from about 11.06pm to 1.27am that night.

Honolulu police are investigating it as second-degree robbery. No arrests have been made.

"I was a little bit nervous going into 16," Allenby said. "I wasn't really sure what to expect. But I just knew it was going to be loud. I was just like, 'You know what? Just go with the flow and have fun with it. Just don't let it get to you.'

"And they were actually really good. I was actually really surprised.

"They were fantastic. There was nothing mean at all. ... I think some of the comments were actually pretty funny."

Allenby bogeyed the par-4 11th - his second hole of the day - after hitting his approach over the green, birdied the par-5 13th with a delicate downhill chip to three feet, and bogeyed the 16th after hitting into the right front bunker.

On his final nine, he made an eight-foot birdie putt on the par-3 fourth and a 14-footer on the par-4 sixth.

"Felt a little bit nervous on the first nine holes," Allenby said. "Just understandable with what's been going on, and very hard to put it all to the side when you're out there. I tried my absolute best and I think I did a really, really good job overall."

Allenby, who has 22 worldwide titles - his last victories in consecutive weeks in 2009 in the Nedbank Challenge in South Africa and Australian PGA - said he played through headaches in Phoenix.

"For some reason I had really bad headaches in my left eye before I teed off and I don't know if that was just nerves, anticipation, what it was," Allenby said.

"But I took some (pain relievers), just to sort of take the edge off a little bit. It sort of went away a little bit. But it was there. It could be allergies, as well, with the desert."

Aaron Baddeley and Geoff Ogilvy were the best of the Australians at three-under while Tiger Woods was tied for 104th at two-over.
