Golf's governing bodies have responded to Dustin Johnson's penalty at the U.S. Open by introducing a local rule that will waive the one-shot penalty if a ball moves on the putting green by accident.
The local rule, effective in January, applies only to accidental movement on the putting green of the golf ball and a ball marker.
Johnson was lining up a par putt on the fifth hole of the final round at Oakmont when his ball moved slightly and he backed away. He said he didn't make it move, but after the USGA studied video and consulted the rule book, he eventually was given a one-shot penalty because it was ruled that his actions caused the ball to move. Even with the penalty, he closed with a 69 and won by three shots.
