Jason Dufner held his nerve to produce a two-under round of 68 to win the PGA Championship on Sunday at Oak hill.
The 36-year-old duelled with veteran Jim Fuyrk to win his first major title with a score of 10 under par after agonizingly losing a playoff to Keegan Bradley in the same competition two years ago.
Dufner, who started the day one shot off Fuyrk, headed top of the leader board after consecutive birdies on holes four and five. He then managed to make that top spot his own after producing some scintillating golf under intense pressure.
The American showed no early signs of faltering after a series of pin-point wedge shots left him with another tap-in birdie on eight to go out in 32.
His playing partner Fuyrk bogeyed the ninth to put himself two shots off the lead heading into the back nine. Both players then parred six holes on the trot before two birdies on 16 meant Furyk needed Dufner to falter heading into the final two holes.
The 43-year-old, who won his first and only major in 2003, bogeyed the 17th meaning Dufner had all but secured his impressive victory in Rochester.
He told Golf365 after, "I come across as a pretty cool customer I guess but there are definitely some nerves out there when you are trying to win a major championship.
"It probably has not sunk in. I can't believe this is happening to me. To come back from a couple of years ago when I lost in a play-off feels really, really good.
"My name will always be on that trophy and no-one can take that from me. It's a great accomplishment for me."
Henrik Stenson was firmly in the mix after his eagle at the par five, fourth, put him to eight-under for the tournament.
After narrowly missing another eagle putt on 13, he played the final five holes two-over par to all but end his hopes of becoming the first Swede to win a major.
His Swedish counterpart and surprise package of the tournament Jonas Blixt also put himself in contention after recovering from two bogeys in the first two holes to notch four birdies through 14 and put him at eight-under.
It was a disappointing day for Brit Lee Westwood. Still searching for his first major, it was a familiar story with the putter, missing a series of short birdie and par putts to end his day six-over and three-over for the tournament.
Rory McIlroy, re-captured some of the form he has been missing over the last year and had an outside chance before a triple bogey on the daunting seventh ended his chances of his third major win.
The world number one’s major drought will continue into its sixth year after Tiger Woods failed to shoot below par on each of his four days.
