LA QUINTA, Calif. -- Duffy Waldorf rolled in eight birdie putts, didn't make a bogey, and still had lots of company atop the leaderboard.
Waldorf's 8-under-par 64 in yesterday's opening round of the Bob Hope Chrysler Classic was only good enough to put him in a five-way tie for the lead.
Fred Funk, Robert Damron, Ted Purdy, and Joe Ogilvie also opened the five-day tournament with 64s.
Fred Couples, the 1998 champion, had a 65 and was in another group of five in the desert tournament where scores traditionally go extremely low.
Defending champion Phil Mickelson, who also won the event in 2002, shot a 66 and was tied with six others.
Only 13 of the 128 players went over par through the first 18 holes of the 90-hole event.
Mike Weir, the 2003 Hope champion, opened with a 71, leaving him tied for 93d.
The players rotate among four courses for the first four days of the pro-am, then the low 70 pros and ties play the final round at PGA West on Sunday.
Waldorf, looking for his first win in almost five years, began his round at PGA West by rolling in a 6-foot birdie putt on the first hole, then finished it with a fine shot out of the bunker and a 4-foot birdie putt on the final hole.
He was deadly accurate with his irons most of the day, usually leaving him within close birdie range.
"Accuracy and good putting for me today," Waldorf said.
Couples was pleased with his round, but cautious about getting too greedy. "You can't go around thinking you're going to shoot 7 under out here every day," he said after his round at Tamarisk Country Club. "What I'm trying to pay attention to is how I'm hitting the ball."
Mickelson, coming off a tie for 56th at Torrey Pines in his 2005 debut, said his play around the green needs improvement. "My short irons, certainly that's an area I need to work on a lot this week," said Mickelson, who beat Skip Kendall in a playoff to win the Hope last year.
David Duval shot a 10-over 82 at PGA West, 23 shots more than he took when he won the tournament on the final day six years ago, when he shot a tour record-tying 59 on the same course.
