PGA champion Hubert Green birdied his final hole for an eight-under-par 63 Thursday and a one-stroke lead in the first round of the $500,000 Phoenix Open.
"A fun round of golf," said the 39-year-old veteran, who scattered nine birdies across his card, including a 20-footer on his last hole at the Phoenix Country Club.
At 64 were defending champion Calvin Peete, former PGA champion Hal Sutton, Australian Greg Norman and Larry Mize.
Norman inadvertently violated a standard of golf etiquette when he drove the green on a 320-yard par-four hole, hitting into a crouched Jack Nicklaus, who was studying a birdie putt.
"I saw the ball out of the corner of my eye and stepped back from the putt," Nicklaus said. After a moment he returned to the putt and made it, for one of the few birdies he was able to convert on the warm, sunny day.
