Louis Oosthuizen and Bubba Watson could be headed to a playoff as long as Phil Mickelson doesn't do anything superhuman on his final hole.
Oosthuizen left the door slightly open for Watson on the final hole when his approach shot carried up the hill leaving a tricky downhill putt for birdie. Ooshuizen's birdie attempt just missed but he mastered the speed of the putt and prevented it from running too far by.
Watson's approach carried off to the right but left him with a fairly level putt that he missed to the right. Watson tapped in for his par and Oosthuizen made his par putt back up the hill to force an eventual playoff.
Watson and Oosthuizen will wait for Phil Mickelson and Jason Hanson to finish their round before beginning the playoff at the 18th hole.
