Until he won the P.G.A. Championship Sunday, Jason Dufner had succeeded on a large scale in only one thing: being so thoroughly Jason Dufner that the Internet turned him into a meme. Yes, thanks to one timely photograph of Dufner slumped against a wall while visiting a childrenâs classroom, you needed to know nothing else about him to laugh at what had become known as Dufnering.  And until Sunday, Dufner was O.K. with that. So much so, it was reasonable to hope he would pose that way with the Wanamaker Trophy. He probably preferred this image to people remembering him as the guy who could not claim that trophy two years ago after he choked up a five-shot lead in the P.G.A. Championship, dunking a tee shot and reeling off three straight bogeys to help crown Keegan Bradley.  But now Dufner has rewritten his image entirely, Sundayâs final round at Oak Hill serving as one big eraser. In one day, his laconic nature went from borderline hilarious to brilliant, his signature stoicism worth its weight in trophies. He built a two-shot lead and nursed it through an entire round, his nearest competitors fading whenever they neared a chance to put pressure on him.

Jim Furyk got his heart broken again in a major, Ian OâConnor writes on ESPN.com; Tiger Woods turned up ordinary in another major, Cameron Morfit chronicles on Golf.com; and Phil Mickelsonâs dreadful tournament could be summed up in a single shot:  And there was a hole-in-one Sunday, courtesy of Tim Clark at No. 11.

Fan Screams "Mash Potatos" As Tiger Woods Tees Off At PGA Championship  Of course, if golf and its absurd fans arenât your thing, your alternative over the weekend was the 100-meter final at the track and field world championships, which is delightfully over in less than 10 seconds and rechristened the sportâs over-the-top personality, Usain Bolt.

There was, oddly, something soothing about watching Dufner amble around Oak Hill Sunday, whatever he was feeling locked tightly behind a sleepy face. Hey, not just anybody can start his own Internet craze, by being as far from crazed as humanly possible. Long live Dufnering.
