A complete game is different from an official game. A pitcher can throw a complete game if he or she pitches every inning until the final out is made. In the major leagues it is usually 9 innings. An official game also has a definition. After the 5th inning, in the major leagues, it is an official game. If the home team is winning by the middle of the 5th inning and the game is called due to weather or some other reason there is no need to play the bottom of the 5th for the game to be considered an official game. Whomever is in the lead at the end of the 5th inning or later is considered the winner.
It looks like you're asking what a complete baseball game is. A full game is played in 9 innings, considering there is no tie, but during bad weather or any other phenomenon that may end a game early, a game is considered a complete game after the 5th inning and the score is final if ended from then on.
When a starting pitcher pitches a game from start to finish he is credited a complete game.
If the game does not have enough innings to be considered a complete game (4 innings) than the game is post poned to a different day. The game picks up where it left off.
In MLB, the team that is behind must have at least five full at bats for a baseball game to be considered complete. If the home team is ahead, the game must go 4 1/2 innings. If the home team is behind, the game must go 5 innings.
It's pretty simple really - a pitcher is credited with a complete game if he is the only pitcher for his team in an official game. There is some argument as to whether a pitcher would be credited with a complete game if say, the starting pitcher didn't get any outs, then a reliever came in and finished the game. He got all the outs in the game - so did he get a complete game? Semantics, semantics...
it depends on what inning the game is in if its after the 5th inning then its considered a complete game and they call it but if its before the 5th inning then they'll suspend it
4 innings are considered a complete game.
