PHOENIX (AFP) — American Scottie Scheffler takes a two-shot lead over Jon Rahm and Nick Taylor into the final round of the Phoenix Open, where he's in search of a title repeat and a chance to regain the world number one ranking.

Scheffler, who started the round tied for the lead with Canadian Adam Hadwin, had four birdies in a three-under-par 68 for a 13-under par total of 200 at TPC Scottsdale.

That was two clear of third-ranked Spaniard Jon Rahm, who also carded a 68, and Canada's Taylor, who posted a 67.

Rahm, like Scheffler, can overtake Rory McIlroy atop the world rankings on Sunday, the Northern Ireland star looking unlikely to challenge the leaders after a third-round 70 that left him tied for 28th, 10 shots off the lead.

Scheffler kickstarted his round with a 47-foot birdie putt at the second hole and picked up another stroke with a 15-footer at the fourth. After his lone bogey of the round at the 13th he fired out of the rough to four feet at the 14th for another birdie.

He'd add one more at the par-four 17th, where his second shot raced up the side of the green, looking scarily close to rolling into the water before it settled just off the putting surface. He rolled in an 11-foot birdie putt from there.

"Feel good," Scheffler said. "I didn't hit it as well today as I hoped to. But still got around in three-under. Kept the ball in play for the most part. Just kept plugging along."

"Only one bogey was good today," he added.

Scheffler posted his first PGA Tour win in Phoenix last year and went on to win at Bay Hill and The Masters before reaching number one in the world with a victory at the WGC Match Play.

He's since seen McIlroy return to the top, while Rahm has been a dominant figure this year with victories in successive starts at the Tournament of Champions and in La Quinta, California.
