Greg Norman, who has made a lively debut at the Augusta National Golf Club, isn't the slightest bit edgy about going into the final day of his first Masters Tournament in third place, just two strokes behind Tom Watson and one behind Jack Nicklaus.

Nervous? Are you kidding? This guy shoots sharks as a hobby.

After regestering a bumpy (four birdies, four bogeys) even par round of 72 today to go with his 69 and 70 of the first two days, Norman was asked what he likes to do to relax. "I do a lot of fishing and shark shooting, if you've ever heard of that," said the affable, 26-year-old Australian.

No one had, so Norman explained.

Moreton Bay, near his home just outside Adelaide on Australia's Gold Coast, is the world's largest breeding ground of sharks. Last year he bought a 25-foot boat to do some fishing there, but most of what he caught was eaten by sharks before it could be pulled from the 120-foot-deep water.

"I have a friend I normally go pig hunting with, so we decided to take our hunting rifles out with us on the boat and shoot sharks as they came to the top. It's a nice little sport," he said."I believe I'm the only one who does it."

What does he do with a shark after he kills it?

"What would he do with you?" responded Norman, 26, with a grin as bright as his platinum hair. "He'd just leave you there. We just leave them there for the other sharks to eat."

Is this sport dangerous?

"The sharks come around the boat, obviously, and they get a feeding frenzy, eating other sharks that have been shot," he said. "But they're not going to attack you or the boat, hopefully. Of course, if I'm not back here next year, you know what happened."

Moreton Bay is inhabited by many types of sharks, including one that was measured from photos to be 29 feet, 6 inches long. A shark hunter caught it on a four-foot stainless steel hook the size of a man's wrist, but the shark broke the hook and got away. Norman said he hasn't gone after that big boy, but he never backs off a 12- or 15-footer.

What odds would he put on himself bagging both Watson and Nicklaus -- "pretty big sharks," as he called them -- at Augusta National on Sunday?

"I suppose I'd have to be a pretty good shot, wouldn't I?" said Norman, a mighty hitter who has assurance in his short game.

Stranger things can happen on the final day of the Masters.

"I'm sitting in a pretty good position," said Norman, a confident 6-foot-1, 182-pounder who took up golf at 17 after competing in swimming, surfing and football. "I don't have much pressure because not that many people over here know about me. I can enjoy myself and go out there and play some golf. If I can shoot a good round, who knows? Maybe I can set a few things on fire."
