Is a Stray Ball on Court Always a Let?
Call a let immediately when it creates a safety hazard, but do not use it to reverse a result after the point has ended.

Start with this check
A ball from an adjacent court or a ball lying on court can be dangerous, but you may not wait to see whether the point benefits you before choosing a let.
Try these steps in order
- When a dangerous ball enters the court, call "Let!" loudly and stop play immediately.
- Before a point, respect a reasonable request to remove balls and obstacles from the court.
- If the ball in play strikes another ball lying on court, follow the official rules and the official's ruling for that special situation.
Bottom line
A let for an outside ball addresses a safety-related hindrance identified immediately, not the outcome of the point.
