Golf is open to all
Ball in motion deflected - Ball deliberately stopped by person
If your ball in motion played from the putting green has been deliberately deflected or stopped by a person or if it hits equipment or other object (except a ball-marker) that has been deliberately positioned, then the stroke must be replayed.
You get the general penalty if you (or your caddie) deliberately deflect or stop any ball in motion.
Except there is no penalty if you deliberately deflect or stop an opponent’s ball in motion in match play at a time when there is no reasonable chance it can be holed, and when done either as a concession or when the ball needed to be holed to tie the hole.
