SCOTTSDALE, Ariz. - Harrison Frazar separated himself from his challengers with a birdie on the 17th hole Saturday, and took a one-stroke lead into the final round of the Phoenix Open.
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 at 4-under-par 67 for a 54-hole score of 17-under 196.
John Huston, who carded 66, and Tim Petrovic, Frazar's co-leader at the midpoint, were at 197.
Huston caught up on the 14th hole, but lost his birdie touch there; Petrovic, who shot 68, 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.
Both Vijay Singh, the 1995 Phoenix champion, and Retief Goosen shot 65s to pull into a three-way tie at 198 with Kirk Triplett. He had 63.
David Toms (63), Robert Gamez (64), Steve Stricker (68) and Scott McCarron (68) were three shots off the lead.
Defending champion Chris DiMarco, third last week in Honolulu, headed the group at 200. His 62 matched Frazar's opening round and Stricker's second-round performance for lowest score of the tournament, and it set a nine-hole record for the TPC of Scottsdale - 7-under 28 on the front side.
Also at 200 were three-time winner Mark Calcavecchia, who set a then-PGA record by winning at 28-under 256 in 2001, Joe Durant and Chad Campbell.
SINGAPORE MASTERS: Ernie Els bogeyed the last two holes in a round of 2-under-par 70, and held a two-shot lead heading into the final round.
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 Zhang Lian-Wei, who moved to 8-under 208 after 69.
Prayad Marksaeng and Simon Yates are tied for third at 209. Five players, including local favorite Lam Chih Bing and Maarten Lafeber, were at 211.
