All the players are given the grounds rules before teeing off on Thursday. If he had any doubt, he could have summoned an official.

Tough break, Especially when even the head groundskeeper could not say how many bunkers there are on the course.

Let me put a 5-6 foot wall of people 8 feet away from you and see how clear your surroundings are - PGA should have better controls on this

Nice "bunker" similar to those on the water's edge. Officials should have forseen potential problems and declared unmaintained bunkers roug

A rule is a rule, but I have never heard of it before.

He knows you can't ground your club in a bunker or trap. It's a rule of golf. Anyone who plays knows the rule

It's the right call according to an awful rule. You can't say it's a bunker and then let people trample all over it all week.

its a penalty, the PGA made all players aware about the tons of bunkers around. too bad, it was a mistake & i was rooting for him

The way I read it, he grounded his club while outside the bunker his ball was in. The rule is to prohibit a player from improving his lie.

All he had to do was ask for a ruling before getting to his ball.

People all over, no rakes, no clear boundaries, grass growing in it - how could he know it was a bunker?

Rules officials rarely err especially in a situation like this. It's unpopular for sure. But Dustin violated the local rule and was penaliz

With warning posted in the locker room and the bunker situation being first item addresses in local rules, he should have been aware.

The officials on the scene did not make the call, they used video in the back. The original call was putting a golf bag in the bunker.

in a major championship there should never be a question whether a player is in a hazard or not

The PGA showed poor course management by allowing fans to stand in what they called a "fairway bunker".

When the PGA official gave the decision on CBS, it was pretty clear Johnson violated the rules. Bummer though - he had a great tourney!

I blame the officials for not moving the spectators from DJ view of play. It was thier responsibility..it was NOT a bunker from our view.

I have never seen the gallery allowed to stand in the bunkers, but officials were letting them stand there because it was not a bunker.

local rule p[revails and it is that simple, sad but simple

The players were all warned of bunkers inside and outside of the rope line. He grounded his club 3 times in that hazard. Rules rule the gam

He read the supplemental rulings as posted. He could have asked an official for a ruling before his next shot. No excuses.

The crowd should not be allowed to mass in "bunkers". This was clearly a spectator viewing area and Johnson should not have been penalized
