With a 26-foot birdie on the final hole at TPC Four Seasons, Dufner won the HP Byron Nelson Championship by a shot at 11 under par.
After a pair of bogeys in the first three holes, Dufner rallied with six birdies into the clubhouse against just one bogey. The Auburn product birdied two of the last three holes to shoot 3-under 67 and take the win.
Dufner is the second multiple-time winner (Hunter Mahan) this season on the PGA Tour, taking the Zurich Classic of New Orleans last month for his first PGA Tour win.
Dicky Pride capped off an outstanding week and second-place finish with an incredible par. After pulling his tee shot left into a water hazard at the 18th, Pride managed to get up-and-down from 158 yards for a par and a closing 67.
