Jason Dufner is a pretty relaxed guy on the golf course. It's something you've heard in the past from writers and commentators, but Dufner basically floats around the golf course with his monotone attitude and sweet golf swing.

On Thursday at the Chevron World Challenge World Challenge presented by Northwestern Mutual, Dufner knocked in his third shot on the par-4 14th and went for the pound with Keegan Bradley.

Bradley treated Dufner like a USGA official, going cold on the pound only to produce a smile out of both players.

Dufner finished his day with a 1-over 73, four shots back of Bradley, who trailed leader Nick Watney by two.
