For someone who has spent his career chasing big-name players, Harrison Frazar knows how to play with the lead.

Frazar separated himself from his challengers with a birdie on the 17th hole yesterday and took a one-stroke lead into the final round of the Phoenix Open.

"I can't get too far ahead of myself," said Frazar, who has led from the start. "The names on the leader board behind me are pretty stout, so you know they're going to be coming after me."

Frazar weathered a dry spell on the back nine that dropped him into a four-way tie at one point. But none of his nearest pursuers could match him down the stretch.

The 31-year-old Texan finished with a 4-under-par 67 for a 54-hole score of 17-under 196.

John Huston and Tim Petrovic, Frazar's co-leader at the midway point, were next -- Huston after a 66 and Petrovic after a 68.

Huston caught up on the 14th hole, but lost his birdie touch there; Petrovic blew his chance to share the lead when he missed the fairway on the 18th hole for the third straight time, leading to a par.

"I got up and down most of the time and made a couple of big putts on the back nine just to keep me in the tournament, so I'm pretty happy with that," Petrovic said.

Defending champion Chris DiMarco shot a 62, matching Frazar's opening round and Steve Stricker's second-round performance for lowest score of the tournament.

DiMarco also set a nine-hole record for the TPC of Scottsdale -- 7-under 28 on the front side.

Frazar, still looking for his first victory after five injury-plagued years on the PGA Tour, had a chance to open a two-shot lead on Petrovic and Huston on the 10th hole. His approach shot landed less than six feet from the cup, but his uphill putt hit the rim and popped out.

* SINGAPORE MASTERS: Ernie Els bogeyed the last two holes in a round of 2-under 70 and held a two-shot lead heading into the final round of the tournament.

Els, coming off consecutive PGA Tour victories in Hawaii, held a five-shot lead midway through the third round before bogeys at Nos. 17 and 18 at the Laguna National Golf and Country Club.

Els is at 10-under 206, two strokes ahead of China's Zhang Lian-Wei, who moved to 8-under 208 after a 3-under 69.

Thailand's Prayad Marksaeng and Scotland's Simon Yates are tied for third at 209. Five players, including local favorite Lam Chih Bing and Dutchman Maarten Lafeber, were at 211.

* CHAMPIONS TOUR SKINS GAME: Lee Trevino won the event in Wailea, Hawaii, holing a 10-foot birdie putt on the third extra hole to finish with six skins and $240,000.

The 63-year-old Trevino won the event for the first time in seven starts, earning $100,000 with his birdie on the par-4 17th.

Hale Irwin was second with $200,000, Jack Nicklaus made $160,000 and Arnold Palmer, the 73-year-old crowd favorite, failed to take a skin for the second straight year.

Harrison Frazar hits from the second fairway during the third round of the Phoenix Open. He is looking for first win after five years on the PGA Tour.
