Johnson up 1 on 18, par to win. Pushes drive wayyyyyyy right. Into some dirt. Grounds club, strokes one left of the green. Beautiful third shot sets up for par putt to win.
Misses the putt. No big deal, playoff time.
But wait! The PGA says he grounded the club (which he did) on second shot in the bunker... BUNKER?! How can that possibly be considered a bunker?!
Now the kid goes from 1st place to out of the playoff because of a penalty that he wasn't even aware should have been in play. Assuming of course the PGA decides that way.
Ridiculous, in my view.
