Hi I'm new to this forum. Still can't figure out how to post a new question So I'm replying to this similar one. I have a friend who ground his putter After he had aligned his ball. Then he picked up the ball and realigning it again While keeping the putter in place. Is this legal?
This might help.
Method Used to Mark Position of Ball
Q.The Note to Rule 20-1 provides that "the position of a ball to be lifted should be marked by placing a ball-marker, a small coin or other similar object immediately behind the ball." Is a player penalized if he uses an object that is not similar to a ball-marker or small coin to mark the position of his ball?
A.No. The provision in the Note to Rule 20-1 is a recommendation of best practice, but there is no penalty for failing to act in accordance with the Note.
Examples of methods of marking the position of a ball that are not recommended, but are permissible, are as follows:
- placing the toe of a club at the side of, or behind, the ball;
- using a tee;
- using a loose impediment;
- scratching a line, provided the putting green is not tested (Rule 16-1d) and a line for putting is not indicated (Rule 8-2b). As this practice may cause damage to the putting green, it is discouraged.
However, under Rule 20-1 it is necessary to physically mark the position of the ball. Reference to an existing mark on the ground does not constitute marking the position of a ball. For example, it is not permissible to mark the position with reference to a blemish on the putting green.
When moving a ball or ball-marker to the side to prevent it from interfering with another player's stance or stroke, the player may measure from the side of the ball or ball-marker. In order to accurately replace the ball on the spot from which it was lifted, the steps used to move the ball or ball-marker to the side should be reversed.
