|9.16 BALLS MOVING SPONTANEOUSLY - 5 SECOND RULE (9-BALL RULE)|
A shooter's shot is considered completed after all balls have come to a final resting position. If, within five (5) seconds of all balls reaching their final resting position, a ball shifts, turns or otherwise moves by itself, the ball shall remain in the position it assumed and play continues.
A hanging ball that falls into a pocket by itself after being motionless for 5 seconds (or longer) shall remain pocketed and play will continue. If the hanging ball is the 9-ball, the 9-ball should be replaced and play continues. If the hanging ball is the cue ball, the cue ball should be replaced as near as possible to their original position immediately prior to the incident.
NOTE: In regard to coaching leagues, no coaching is allowed once all balls come to rest and it is the incoming player's turn at the table.
