New Rule Changes – as explained by Golf professional Gavin Beck

When a player’s ball lies on the putting green, there is no penalty if the ball or ball-marker is accidentally moved by the player, his partner, his opponent, or any of their caddies or equipment.

The moved ball or ball-marker must be replaced as provided in Rules 18-2, 18-3 and 20-1.

This Local Rule applies only when the player’s ball or ball-marker lies on the putting green and any movement is accidental.
