4.12 SUSPENDED GAMES.
(a) A game shall become a suspended game that must be completed at a future date if the game is terminated for any of the following reasons:
(1) A curfew imposed by law;
(2) A time limit permissible under league rules;
(3) Light failure or malfunction of a mechanical field device under control of the home club. (Mechanical field device shall include automatic tarpaulin or water removal equipment);
(4) Darkness, when a law prevents the lights from being turned on; (5) Weather, if a regulation game is called while an inning is in progress and before the inning is completed, and the visiting team has scored one or more runs to take the lead, and the home team has not retaken the lead;
(6) It is a regulation game that is called with the score tied.
National Association Leagues may also adopt the following rules for suspended games. (If adopted by a National Association League, Rule 4.10(e) would not apply to their games.):
(7) The game has not become a regulation game (4½ innings with the home team ahead, or 5 innings with the visiting club ahead or tied).
If a game is suspended before it becomes a regulation game, and is continued prior to another regularly scheduled game, the regularly scheduled game will be limited to seven innings.
(9) If a game is suspended after it is a regulation game, and is continued prior to another regularly scheduled game, the regularly scheduled game will be a nine inning game.
EXCEPTION: Optional Rules 4.12(a)(7), 4.12(a)(8) and 4.12(a)(9) for National Association Leagues will not apply to the last scheduled game between the two teams during the championship season or league playoffs.
No game called because of a curfew (Rule 4.12(a)(1)), weather (Rule 4.12(a)(5)), a time limit (Rule 4.12(a)(2)) or with a tied score (Rule 4.12(a)(6)) shall be a suspended game unless it has progressed far enough to have been a regulation game pursuant to Rule 4.10(c). A game called pursuant to Rules 4.12(a)(3) or 4.12(a)(4) shall be a suspended game at any time after it starts.
NOTE: Weather and similar conditions—Rules 4.12(a)(1) through 4.12(a)(5)—shall take precedence in determining whether a called game shall be a suspended game. If a game is halted by weather, and subsequent light failure or an intervening curfew or time limit prevents its resumption, the game shall not be a suspended game. If a game is halted by light failure, and weather or field conditions prevent its resumption, the game shall not be a suspended game. A game can only be considered a suspended game if stopped for any of the six reasons specified in Rule 4.12(a).
