- Regression occurs when a player plays a shot from within a penalty area and the shot doesn't leave the penalty area, goes into another penalty area, or goes out of bounds.
- In all of these cases the player always has the option (with 1 penalty stroke) to proceed according to the penalty area rule based on the shot which entered the penalty area, regardless of how many shots occured from within the penalty area.
- For example, if a player hits his or her tee shot into yellow penalty area and leaves his or her 2nd shot in the same penalty area, the player may:
- Play the ball from the new location in the penalty area.
- Drop the ball in the penalty area under stroke and distance with respect to the prior shot with 1 penalty stroke.
- Drop the ball outside the penalty area using back-on-the-line relief with 1 penalty stroke from where the original shot entered the penalty area.
- Or, hit again from the tee under stroke and distance with 1 penalty stroke with respect to the original shot which entered the penalty area.
- For a shot hit out of bounds from a penalty area, the player may:
- Drop the ball in the penalty area under stroke and distance with 1 penalty stroke. At this point, for an additional penalty stroke, the player still has the last 2 options above available.
- Or, proceed directly outside the penalty area with 2 penalty strokes (1 for out of bounds and 1 for leaving the penalty area) using either of the last 2 options above.
