Jason Dufner had a four-stroke lead after hole 14, when he watched Keegan Bradley triple bogey 15. Then, Dufner hit in the water on 15, too, but managed to save the hole with a bogey.
Saving is not how you'd describe his next two holes, as he went bogey-bogey to open the door for Keegan Bradley, who proceeded to birdie 16 and 17, bringing the PGA Championship down to the wire.
Bradley proceeded to par 18, finishing his round at -8. Dufner has a long, long birdie attempt to try to win, and will need to two-putt to force a playoff. Playoff scoring rules is the best three-hole aggregate score wins, not a sudden-death hole-by-hole like many tournaments.
This championship will come down to Dufner's ability to make putts in the clutch. Bradley already proved he can do just that.
