Rule 28. Ball Unplayable
The player may declare his ball unplayable at any place on the course
except when the ball is in a water hazard. The player is the sole
judge as to whether his ball is unplayable. If the player deems his
ball to be unplayable, he shall, under penalty of one stroke:
a. Play a ball as nearly as possible at the spot from which the original
ball was last played (see Rule 20-5); or
b. Drop a ball within two club-lengths of the spot where the ball
lay, but not nearer the hole; or
c. Drop a ball behind the point where the ball lay, keeping that
point directly between the hole and the spot on which the ball is
dropped, with no limit to how far behind that point the ball may be
dropped. If the unplayable ball is in a bunker, the player may proceed
under Clause a, b or c. If he elects to proceed under Clause b or
c, a ball must be dropped in the bunker. The ball may be cleaned when
lifted under this Rule.
Penalty for Breach of Rule:
Match play-Loss of hole; Stroke play-Two
strokes.
