Chad Campbell kept chipping away at par Friday in the Bob Hope Chrysler Classic, shooting a 4-under 68 for a four-stroke lead after three rounds in Palm Desert, Calif.

He went to 19-under 197 through 54 holes of the 90-hole event. Scott Verplank had a 65 and John Senden a 68 to tie for second.

Phil Mickelson, who won the Hope in 2002 and 2004 and is making his first start of the year, had a 68 that left him six shots off the lead. Pat Perez tied him for fourth at 13 under, shooting a 70.

A model of consistency, Campbell finally had his first bogey of the tournament on his 17th hole of the day, No. 8 on the Arnold Palmer Course at PGA West. That ended a string of 60 consecutive holes without a bogey dating to his runner-up finish in Hawaii last weekend.

He has had two bogeys in 96 holes, and couldn't clearly recall the last one before the Hope.

"Honestly, I don't remember," Campbell said. "I'm sure it was in Hawaii, the final round somewhere."

The latest was vivid in his memory, of course.

"I hit a bad tee shot, in the fairway bunker, then I caught it a little heavy and hit it in the bunker short of the green, then missed about a 20-footer for par," Campbell said. "It was just kind of a nightmare hole for me."

The players rotate among four courses for the opening four days of the Hope, with the first 72 holes a pro-am before the field is reduced to the 70 low-scoring pros and ties for the final round.

Campbell will play the fourth round over the new Classic Course at Northstar, considered the most difficult of the four courses and the site of Sunday's final 18 holes. Gusting wind had made the layout especially difficult earlier in the week.

"Obviously, it's been the hardest course," Campbell said. "I'm looking forward to playing it. If the wind is not blowing, you can make some birdies. In turn, if the wind is blowing, a couple under is a great score."

Campbell had taken a four-shot lead with a second-round 66 at La Quinta Country Club as Perez, who opened with a 60, struggled to a 73 during a windy second round at the Classic Course. Perez followed with a 2-under round at Bermuda Dunes Country Club on the third day to remain in the hunt.

MASTERCARD CHAMPIONSHIP: At Kaupulehu, Hawaii, Tom Watson, Loren Roberts and Don Pooley matched the course record with 9-under 63s in calm conditions to share the first-round lead in the Champions Tour's season-opening MasterCard Championship.

Watson, Roberts and Pooley tied the Hualalai record set by Tom Kite in 2002 and also matched by Fuzzy Zoeller (2003) and Craig Stadler (2004).

ABU DHABI GOLF CHAMPIONSHIP: At Abu Dhabi, United Arab Emirates, South Africa's Charl Schwartzel shot a 6-under 66 to take a one-stroke lead. Denmark's Soren Hansen and Argentina's Ricardo Gonzalez (68) were tied for second, Vijay Singh (68) and Chris DiMarco (67) topped a group at 6 under, and Sergio Garcia (69) was 5 under.

WOMEN'S WORLD CUP: At Sun City, South Africa, Annika Sorenstam and Liselotte Neumann shot a 7-under 65 in best-ball play to give the Swedes a share of the first-round lead with South Korea's Meena Lee and Bo Bae Song in the Women's World Cup.
