LAS VEGAS, Nev. (AP) -- Chad Campbell made a double bogey on the par-5 16th hole, then birdied the 18th for a 4-under 67 and a share of the third-round lead with Scott Piercy in the Justin Timberlake Shriners Hospitals for Children Open on Saturday.

Piercy -- a Las Vegas local whose wife, Sara, delivered son Jett on Thursday -- had a 65 to match Campbell at 17-under 196 at TPC Summerlin.
Martin Laird (67) was a stroke back, and 2007 winner George McNeill (63), Jason Bohn (65), Jeff Klauk (66) and Bob Heintz (68) followed at 15 under.
After eagling the par-4 12th and adding birdies on 13 and 15, Campbell dropped two strokes with the double bogey on 16.
"I was pretty upset with myself after that kind of a bad shot," said Campbell, who won the last of his four U.S. PGA TOUR titles in 2007. "I was aiming 20 feet right of the hole, but pulled it toward the pin and low. Unfortunately, it didn't carry. That's the way it goes. But it was nice to end on a birdie."
Piercy, winless on the U.S. tour, had seven birdies and a bogey. He also topped the leaderboard after three rounds in his last start, but closed with a 73 to tie for 12th at Turning Stone on Oct. 3.
"It's definitely been a roller coaster," Piercy said. "I think early in the week it was the anticipation of having the baby. And I think emotionally that wears you down. Yesterday, I really felt emotionally drained. I had nothing in the tank.
"The golf course has been kind of a quiet retreat from everything; that I can just kind of punk up and down the fairway and take my time doing nothing."
McNeill had eight birdies in his bogey-free round.
"I have a good feeling when I come here," said McNeill, who missed the cuts in his previous four tour events. "It's always nice to go back to places you played well. That's what I feel like when I show up here. Obviously, my first year winning, and then last year I think I finished 15th."
Charley Hoffman (64) was in a group at 14 under with first-round leaders Troy Matteson (70) and Tom Pernice Jr. (68).
Rickie Fowler (69) was 13 under along with Kirk Triplett (66), U.S. Presidents Cup player Hunter Mahan (67), Greg Chalmers (67) and Ryan Moore (70).

INSIDE THE ROPES WITH THE PGA TOUR NETWORK
PGA TOUR Network correspondent Mark Carnevale offers these observations from Saturday's action. Listen to PGA TOUR Live coverage on XM 146/SIRIUS 209 or right here at PGATOUR.COM.

Scott Piercy will look for his first PGA TOUR victory on Sunday. He told me earlier in the year we would be talking to him quite a bit this year. It's been a good year for Piercy, with a good season on TOUR and the birth of his third child on Thursday night. It would be hard to imagine a better year, especially with a win on Sunday.
Jason Bohn is looking to get back into the Winner's Circle for the first time since 2005. He has fought off a series of injuries and is in good health right now. He lost in a playoff in August at the Wyndham Championship, but his putting has been much improved this week. He told me that he normally reads his own putts and only calls his caddy into to read them when he is unsure. This week he decided to involve his caddy in all putts. He doesn't care if the read is wrong, he feels better with another set of eyes. This week he is tied for 11th in total putts and tied for 9th in putts per greens in regulation -- I would say it is working pretty well.
Martin Laird is one shot back going into the final round. Last year, Laird finished 125th on the money list, not knowing his fate until the last event of the year. Being one shot back, he has a great opportunity to seal his card for 2010 with a great finish. Presently he sits at 134th on the list. I spoke to his teacher Mark McCann Saturday morning, he told me Martin was playing very well and "hitting it a mile". If he continues to do that, he will have no worries for 2010.
