If a player's ball is at rest and slightly moves due to natural causes, what is the ruling?

When a player's ball is at rest and moves slightly due to natural causes, such as wind or water, there is no penalty incurred. The rules of golf recognize that various environmental factors can influence the position of a ball that is at rest. When such a natural cause results in movement, the player is not responsible for that movement and is not penalized.

In these situations, the player is typically required to play the ball from its new location, as it is considered to have been moved by an external force. Therefore, the correct ruling is that no penalty is incurred, allowing the game to continue without penalizing the player for natural occurrences beyond their control. This ruling promotes the principle that golf should be a fair game, recognizing the unpredictable influences of the environment.
