Three years ago at the 2011 PGA, Dufner lost to Keegan Bradley in a playoff at Atlanta Athletic Club. Dufner has struggled since winning the title. His best finish was at Colonial, where he lost a playoff to Adam Scott. Dufner has barely cracked the top 10 since then.
Dufner shared 19th at the Memorial, but missed the cut twice and finished outside the top 50 in his other two starts.
While Dufner is scuffling, the championship will be without Dustin Johnson, who is taking time off to battle some personal challenges. His withdrawal cost the PGA the chance to be the first major to ever have every player in the top 100 in the world ranking in the field.
Four-time champion Tiger Woods is also a question mark with a bad back, which he injured in Akron last weekend. Woods has until Thursday morning to decide whether or not he will play.
Rory McIlroy is the clear favorite entering the year's last major. He has won his last two starts, both by two strokes over Sergio Garcia. Rickie Fowler also ended two back at Hoylake, and that gave Fowler his third straight top-10 finish in a major this season. He is the only player that has done that in 2014.
