<P> An official game in baseball, also sometimes called a regulation game, is a game that has progressed beyond the point at which it can be considered complete if necessary . This is approximately the halfway point of the game . In the case of inclement weather, any game which has reached this point may be stopped and shortened as needed, with the result being final, and all records and statistics counted . A game which has not reached this point before being stopped is either considered a suspended game (to be continued at a later date from the point of stoppage), or is simply canceled and replayed from the start . (This depends on the rules of each individual league .) In either case, no statistics are counted until the game becomes official . </P> <P> Since most professional baseball games are nine innings long, the fifth inning is used as the threshold for an official game . If the visiting team is leading, or the game is tied, the end of the fifth inning marks this point . If the home team (which bats last) is already ahead in the score, and theoretically would not need its half of the fifth inning, then 41⁄2 innings (i.e., the middle of the fifth) is considered an official game . The game is also considered official if the home team scores to take the lead in the bottom of the fifth inning, since the game would end immediately if the same thing happened in the ninth . </P> <P> In nearly all cases, the "official game" status is used to determine whether a rain check will be honored for fans holding tickets . If a game is started but does not reach the point of becoming official, fans are entitled to a new ticket for the make - up game or (in most modern cases) any other available game of their choice . If a game is halted after it becomes official, the game is simply shortened and no rain check is given . </P>
