Rule of the Day

20-3d/3 Ball in Rough Moves Downward When Addressed; Ball Will Not Remain at Rest When Replaced
Q:

A player's ball is sitting up in the rough about three inches above the ground. He addresses the ball. It moves downward about two inches and comes to rest at Point X. The player attempts to replace the ball as required by Rule 18-2b, but the ball falls downward to Point X. Under Rule 20-3d, he again attempts to replace the ball, with the same result. The player must now place the ball at the nearest spot not nearer the hole where it can be placed at rest -- Rule 20-3d.

If the nearest spot where the ball will remain at rest is Point X, must the player place the ball there, even though that point is vertically below the original lie?



A:

Yes.
