Next time there's a WPA World 9-Ball Championship, someone should inform the WPA-hired referee about the contents of the WPA-written rule book.

16. Rack at Nine Ball
As stated in Rule 2.2, balls other than the one and nine are placed randomly in the rack and should not be set in any particular order during any rack. If the referee is not racking, and a player believes that his opponent is intentionally placing balls within the rack, he may bring this to the attention of a tournament official. If the tournament official determines that the player is intentionally positioning balls in the rack, the player will be given an official warning to refrain from doing so. Once warned, should the player continue with intentional positioning of balls in the rack, he shall be penalized for unsportsmanlike conduct.
