Jason Dufner: 'I'm a little anxious'

Joint US PGA Championship leader Jason Dufner has admitted that he is nervous ahead of the final day's play in Atlanta.

The-34-year-old hit a 68 to take a one-shot lead into Sunday along with fellow American Brendan Steele.

"I missed four cuts coming into this event, so maybe I'm a little surprised to be in the final group of a major," Dufner told Sky Sports News.

"Probably I'll be a little anxious. You could probably call it nerves, but I'm anxious to get out there and get going to see how I can stack up."

Dufner has not won an event on the PGA Tour for six years.
