Reader John sent me a link to a thread over at The Hacker's Paradise about a rules situation facing Charley Hoffman at Liberty National.  Here's the gist of it:

Hoffman hit a bad second shot that came up short of the green in one of those tightly mowed bowls below the green.  He tried to hit a wedge up to the hole but stubbed it short onto the green's false front.  Hoffman was furious and whacked the ground with his wedge which sent a big divot flying in two pieces into the air.  One of the divots landed behind his ball which by this time was already rolling backward towards Hoffman - back down into the bowl...except the ball hit the divot and stopped.  The Tour was playing lift, clean and place so Hoffman just marked his ball where it was - jammed up against this divot he had hit there - and then threw the divot away.  His caddy cleaned the ball and he replaced it.

Well, that should have been a penalty stroke.  As a reader noted, the USGA would tell Hoffman that he violated rule 19-2.  Looking under decision 9 associated with that rule:

Q. A player has a short pitch shot to the green. He makes a stroke and, while the ball is still in motion, he makes a subsequent swing and takes a divot out of the ground with his club. The divot deflects or stops the moving ball. What is the ruling?

A. The player is deemed to have accidentally deflected or stopped his ball in motion. He incurs a penalty of one stroke and must play the ball as it lies (Rule 19-2). (New)

Assuming the story is 100% accurante, because Charley did NOT take the penalty stroke he then should be disqualified for signing an incorrect scorecard.

UPDATE: Our friends at the PGA Tour dropped me a line to give us the results of their investigation.  They found that Charley didn't break the rules and had no conclusive evidence to contradict that.  Therefore, no penalty for Charley.

Like the tuna fish commerical: Sorry, Charley.
