(Reuters) - Tyler Duncan held on to his one-shot lead at the Safeway Open on Saturday after carding a one-under-par 71 at the North Course at Silverado Resort and Spa in Napa, Ca. Duncan, playing in just his second PGA Tour start, moved to 14-under and will start the final round with a slender lead over Chesson Hadley, who shot a two-under 70 a day after dazzling with a 61. The big mover of the day was Bud Cauley whose 66 got him into contention on 12 under alongside defending champion Brendan Steele. Emiliano Grillo of Argentina and Graham DeLaet of Canada are at 11-under.
Phil Mickelson shot a four-under-par 68 to reach 10-under and give himself a chance on Sunday.
