Five players had at least a share of the lead at some point in the final round, and mistakes were magnified.
Dufner holed a 60-foot eagle putt on the sixth hole and grabbed a share of the lead with a shot up the hill and into a stiff wind to 4 feet for birdie on the 13th. His mistake was making pars on the short 14th and the par-5 15th, three-putting from long range on the latter.
Masters champion Adam Scott got within one shot of the lead with an eagle on the 15th hole, only for his wedge to hit the flag on the 16th. He had to settle for par, and he closed with a bogey to finish in the tie for sixth. He never was a serious threat to win, though, not with Zach Johnson facing so many easy birdie holes and making it look easy.
