Hmmm... 11 is a worthy candidate also, and damn straight one of the world's greatest par 3's.
But remember Tommy worships at the altar of options. Not many options there except avoid the damn bunker!
I don't see ANY par 3 making his top 3, for just this reason. If one does, it would be 16 Cypress, because options do exist there - for people who play it all the time, plus Dave Moriarty and golfers over 70 years old, anyway.
So I'm gonna stick with #14, the poster-hole for options.
But of course, when Tommy sees this he's likely to pick three from obscure munis only he has seen, just to screw us all.
