Austin Cook, chasing a second US PGA Tour title, fired an eight-under par 64 on Saturday to seize a one-stroke lead through 54 holes of the CareerBuilder Challenge in California.
Cook, who captured his first tour title in November at the RSM Classic at Sea Island, Georgia, fired seven birdies and an eagle and rolled in a tough par-saving putt at the 18th at La Quinta Country Club, one of three courses in use over the first three rounds of the tournament.
He emerged from the third round on 19-under par 197, one stroke in front of fellow americans Andrew Landry and Martin Piller, who are both seeking a first PGA Tour crown.
Overnight leader Landry had two birdies without a bogey in his two-under 70 on the Stadium Course at PGA West, where the final round will also be played on Sunday.
Piller powered up the leaderboard with a five-under 67 at La Quinta, where he teed off on 10 and after making the turn two-under picked up three straight birdies at the fifth, sixth and seventh holes.
Spain’s Jon Rahm, the highest ranked player in the field at number three in the world, held a share of the lead at 19-under after birdies at the 10th and 11th on the Stadium Course.
But bogeys at 13, 15 and 17 were too much to overcome, and he signed for a two-under 70 for 199.
He was tied for fourth with Scott Piercy, who carded a six-under 66 on the Stadium Course.
Despite falling back a bit, Landry was looking forward to battling for a first title on Sunday.
“I’m just going to continue doing what I’ve been doing,” he said. “Just hitting a lot of greens and making some putts.”
He planned to head out to the practice green after a tougher putting day, but put that mostly down to the differences on the putting surfaces among the courses.
The cut, made after the third round after every player had played each course, saw five-time major winner Phil Mickelson and two-time Masters champion Bubba Watson fall by the wayside.
Mickelson carded a four-over 74 to miss the cut by four strokes while Watson signed for an even-par 72 to miss it by five. (AFP)
