Furyk fired a final-round 71 Sunday, finishing alone in second place two strokes back of Dufner, who shot an impressive 68 in winning his first major.
After starting with five consecutive pars, Furyk birdied the par-3 sixth, before bogeying the ninth for an even par front nine. He was solid on the back -- at least until the final two holes -- though he couldn't keep pace with Dufner, who held a two-stroke lead for much of the second nine.
Both players birdied 16, then again matched one another on 17 with bogeys.
There was a touch of drama on the finishing hole -- Dufner missed the green short after missing the fairway -- but Furyk couldn't capitalize, also missing the green and fairway.
The second-place finish was the best of Furyk's career at the PGA Championship, and his highest finish in a major since winning the 2003 U.S. Open.
