Ball (or ball-marker) moved - By wind, water or other natural forces
If natural forces cause your ball on the putting green to move, where you must play from next depends on whether your ball had already been lifted and replaced on the putting green:
  • Ball already lifted and replaced – Your ball must be replaced on the spot it moved from (which if not known must be estimated).
  • Ball not already lifted and replaced – The ball must be played from its new spot.
