PGA Tour rookie Tyler Duncan admits he will be nervous but he is ready to fight for his first title as he prepares to take a one-shot lead into the final round of the Safeway Open.

Duncan, 6.00 to win the title, only graduated from the Web.com Tour last month but he has adapted well so far.

He mixed five birdies with four bogeys on his way to a one-under 71 at the Silverado Resort.

Saturday’s round was his worst of the week but he still did enough to stay one clear of the chasing pack.

Fellow American Chesson Hadley is alone in second on 13-under par after he followed his course-record 61 with a round of 70 on Saturday.

Bud Cauley and Brendan Steele are tied in third on 12-under and still in contention, but Duncan is ready for a battle.

A poor tee shot on the 15th nearly derailed his progress but Duncan insists he is ready to fight his nerves in just his second PGA Tour event.

He told the PGA Tour official website: “I feel OK now, but I’m not sure it’s sunk in yet. But it probably will after dinner when I’m laying in bed.

“I’m sure I’ll be nervous tomorrow, but I am looking forward to it. The shot on 15 was probably the worst shot I’ve hit in a long time. But I made a nice bogey and then made a nice par save on 18.”

Hadley is the 5.25 favourite to win despite sitting in second, while Steele can be backed at odds of 6.00 to climb the leaderboard and win.
