Please note that effective from 16th June 2018 preferred lies (1 hand span, not nearer the hole) have been introduced via Temporary Local Rule #8.

8. PREFERRED LIES
A ball lying through the green may be lifted without penalty and cleaned. Before lifting the ball, the player must mark its position. Having lifted the ball, the player must place it on a spot within one hand span of and not nearer the hole than where it originally lay, that is not in a hazard and not on the putting green.

A player may place his ball only once, and it is in play when it has been placed (Rule 20-4).
