## 3.2 Regulation Games

Games played under the auspices of both recognized Managers of the participating teams shall count as official. A regulation game is defined as follows

1. A regulation game consists of seven (7) innings, unless extended because of a tie score, or shortened because the home team needs none of its half of the seventh inning or only a fraction of it, or because the umpire calls the game in accordance with 3.3 Reasons for a Game to be Called.
2. If the score is tied after seven completed innings play shall continue until (1) the visiting team has scored more total runs than the home team at the end of a completed inning, or (2) the home team scores the winning run in an uncompleted inning. If a regulation game is called with the score tied, it shall remain a tie game.
3. If a game is called by the umpire, per 3.3 Reasons for a Game to be Called, it is a regulation (official) game:
4. If four innings have been completed;
5. If the home team has scored more runs in four or three and a fraction half-innings than the visiting team has scored in four completed half-innings;
6. If the home team scores one or more runs in its half of the fourth inning to tie the score.

Postseason games are exempt from this definition as specified in Completion of Playoff Games. 1. Slaughter Rule: The game shall be ended and the leading team declared the winner: 1. If after 4 complete innings the visiting team is ahead in the score by 15 or more runs, or if after 3½ innings the home team is ahead by the same, the game will be ended and the leading team declared the winner. 1. If after 5 or more complete innings the visiting team is ahead in the score by 12 or more runs, or if after 4½ innings or more the home team is ahead by the same, the game will be ended and the leading team declared the winner.

The Slaughter Rule is applicable for the playoffs as specified in Completion of Playoff Games. 1. If a game is called after 3 complete innings and one team is ahead by 10 or more runs, the game will be ended and the leading team declared the winner.

Postseason games are exempt from this definition as specified in Completion of Playoff Games.

1. If a game is postponed or otherwise called before it has become a regulation game, the umpire-in-chief shall declare it “No Game,” meaning the game must be restarted (not resumed) at a later date.

Postseason games are exempt from this definition as specified in Completion of Playoff Games.
