Rule 25-2 Embedded Ball.
"A ball embedded in its own pitch mark in the ground in any closely-mown area through the green may be lifted, cleaned and dropped without penalty, as near as possible to the the spot where it lay but not nearer the hole. The ball when dropped must first strike a part of the course through the green. "Closely-mown area" means any area of the course, including paths through rough, cut to fairway height or less."
"Through the green" is the whole area of the course except:
a. The teeing ground and putting green of the hole being played; and
b. All hazards on the course.
