Rewind to five years ago when the PGA Championship was last held at Whistling Straits. What do you remember more clearly? Martin Kaymer hoisting the Wanamaker Trophy after beating Bubba Watson in a four-hole playoff? Or Dustin Johnson pushing his drive way right on the 72nd hole and his ball ending up in a sandy area — which had been trampled by thousands of fans and even splattered with trash — where he grounded his club and received a two-shot penalty that took him out of the playoff? Probably the latter, unfortunately.
The 2010 PGA Championship essentially ended in controversy, confusion and dismay — it was one of those majors where it will always be more memorable for how it was lost, rather than how it was won.
