(1) When Ball Is Lost. A ball is lost if not found in three minutes after the player or his or her caddie begins to search for it.
If a ball is found in that time but it is uncertain whether it is the player's ball:
- The player must promptly attempt to identify the ball (see Rule 7.2) and is allowed a reasonable time to do so, even if that happens after the three-minute search time has ended.
- This includes a reasonable time to get to the ball if the player is not where the ball is found.
If the player does not identify his or her ball in that reasonable time, the ball is lost.
(2) When Ball Is Out of Bounds. A ball at rest is out of bounds only when all of it is outside the boundary edge of the course.
A ball is in bounds when any part of the ball:
- Lies on or touches the ground or anything else (such as any natural or artificial object) inside the boundary edge, or
- Is above the boundary edge or any other part of the course.
A player may stand out of bounds to play a ball on the course.
