NAPA, Calif. — PGA Tour rookie Tyler Duncan parred the 18th hole for a scrambling 1-under-par 71 to maintain a one-stroke lead Saturday after three rounds of the Safeway Open.
Duncan, whose only previous PGA Tour event was the 2015 U.S. Open, had five birdies and four birdies to reach 14-under 202 in the season opener at Silverado Resort and Spa.
Former Georgia Tech golfer Chesson Hadley, a one-time PGA Tour winner who had a course-record 61 in the second round, was a stroke back after 70.
Bud Cauley, winless in five PGA Tour seasons, shot 66 to join defending champion Brendan Steele (72) at 12-under. Emiliano Grillo, the 2015 tournament winner, shot 68 to match Graham DeLaet (69) at 11 under.
Phil Mickelson, seven shots behind Duncan entering the round after consecutive 69s, had 68 to join Bill Haas (69), Tony Finau (71) and Andrew Putnam (69) at 10-under.
Mickelson has seven consecutive rounds in the 60s in the event. He finished eighth last year and is seeking is first title since the 2013 British Open.
After a bogey on the second hole, the 47-year-old Mickelson birdied five of his last six holes on the front nine to move to 11-under and within two shots of the lead.
But Mickelson, playing in his 91st PGA Tour event since his last victory, missed a short putt for birdie on the 16th and short putt for par on the 17th. He made a short birdie putt on the 18th.
Aiken resident Scott Brown shot 75 and is at 218.
European Tour: In St. Andrews, Scotland, defending champion Tyrrell Hatton opened up a five-shot lead heading into the final round of the Alfred Dunhill Links Championship.
A bogey-free 7-under-par 65 put Hatton in a commanding position to defend the title he won by four shots last year at St. Andrews, the home of golf.
After opening with 68 on the Old Course on Thursday, he followed that with 65 at Carnoustie, and matched that mark at Kingsbarns to go to 18 under.
Gregory Bourdy is his closest challenger at 13 under after his 66.
Paul Dunne is at 11 under, with former world No. 1 Luke Donald and Ross Fisher a further shot back.
Rory McIlroy shot 68 and made the cut on the number.
Hatton got up to 14th in the world rankings in March before enduring a frustrating summer, but that will all be forgotten should he become the first man to successfully defend this title.
“To win at the home of golf once is incredible, but to do it again and defend would be a dream come true,” he said.
Starting on the back nine, he birdied the 10th, 12th and 14th, hit a brilliant approach to the first, and then did well to get up and down from a bunker on the third. Another birdie on the fourth handed him a six-shot lead.
Bourdy made four birdies in a row from the third at Carnoustie, while Dunne, who claimed a maiden pro win last week at the British Masters, had three birdies and a bogey in a 70 at Kingsbarns.
Fisher birdied six of his last seven holes at Kingsbarns for a 67, and Donald also produced a big finish with four birdies in seven holes.
