There are nine innings in a major league baseball game. If the score is tied after nine innings, the game goes into extra innings and continues until one team or the other is ahead after a complete inning. Games can be called anytime on account of rain, darkness, earthquakes, etc. and can be considered complete or continued at a later date depending on the number of innings completed. A complete game requires at least five innings of play so that the losing team has five at-bats.
A complete game means the entire game. It entirely depends on how many innings are played in the game. I suppose then the answer to your question is nine, as that is the minimum number of innings in an mlb game. If that game goes into extra innings, the pitcher will have to continue to pitch until the end of that game. ---- In MLB, the game must go at least 4 1/2 innings to be considered complete if it starts raining or something else happens to cause the field to become dangerous to play on.
Except in rare occasions when a time limit is agreed to, baseball is not determined by a time clock like basketball, football, soccer, etc., but on number of "innings", generally nine innings, but an official game must be at least seven innings (or 61/2 innings if the home team is ahead).
At least five for the losing team.
If he has pitched at least 5 innings, he can qualify for the win.
10.19 (a) Credit the starting pitcher with a game won only if he has pitched at least five complete innings and his team not only is in the lead when he is replaced but remains in the lead the remainder of the game.
When at least 4.5 innings have been played. Depending on who's winning at that time.
For a Major League Baseball regular season game to be declared a complete game as a result of it being called due to a rained out or snowed out the game needs to have played at least five innings or in the event of the home team leading when the game is called then the home team needs to be winning after 4 and a half innings at which point it will be declared an official game as well.
at least 18
The number of innings doesn't matter if a game is rained out, the number of innings only determines whether a game is an official game or not. A game must have played at least 5 innings for it to count as an official game and if the home team is losing then they must have the chance to bat in the bottom of the 5th inning before it counts as an official game.
ERA stands for Earned Run Average. The number of innings per game determines how ERA is calcuated. In Major League Baseball they play 9 innings so ERA is calculated with this equation, Earned Runs divided by 9. High School baseball (at least where I am located) plays 7 innings as a regulation length game. In this case a pitcher's ERA is Earned Runs divided by 7. In Little League the a regulation game is 6 innings, so ERA would be determined by Earned Runs divided by 6. If you are playing a game and it goes in to extra innings then a pitcher's ERA is not affected by the extra innings. If a regulation game is 6 innings, and the game goes into the seventh inning, then a pitcher's ERA is still determined by # of earned runs divided by 6. In summary ERA is ALWAYS determined by the amount of Earned Runs allowed divided by the number of innings played (not including extra innings).
In NCAA and NAIA college baseball, the game will end if a team is ahead by at least 10 runs after seven innings in a scheduled 9-inning game
