There are three answers to this.
First, the Official Game, or Regulation Game. If a game must be called, it is Official after five innings.
Next, the Complete Game. This is nine innings.
And finally, the Extra Innings Game. The only way a Major League Baseball game can end in a tie is if it's called. The rules state that the game must continue until either someone wins or the umpires call the game, usually on account of darkness. In the 2014 season there were two 19-inning games and a handful of 18-inning games; the longest game was 26 innings. The most important rule in extra innings: if a team can't field nine players, it forfeits.
I will say it is will wright he had 690 innings pitch in a season.
Will white
7 innings for most high schools
He can, but he probably, no, most likely get hurt.
The average length of a spring training baseball game is nine innings. Most baseball games do not go over nine innings regardless of a tie.
There is no limitation to the number of innings a baseball game can be played. In theory, the game could go on forever as long as the teams are tied at the end of an inning. The longest professional game I have heard of is a 33 inning game between Pawtucket and Rochester of the International League (minor leagues) in 1981. The longest MLB game was 26 innings between Brooklyn and Boston in 1920.
In Texas, High School baseball games are 7 innings long, and I believe that is the same around the country. If the game is tied at the end of the 7th inning, it continues until there is a winner.
From 1920 to the present: Season: 376 2/3 innings by Wilbur Wood of the Chicago White Sox in 1972. Career: 5404 1/3 by Phil Niekro between 1964-1987.
By scoring the most runs in nine innings
There are '9' (nine) innings in a regulation Major-League baseball game, and in most semi-professional, college and high-school leagues as well. At lower levels and for younger players, the number of innings may be reduced to 7, or even 5.
The fastball is the pitch most thrown and most hit in baseball.
That would be Will White of the 1879 Cincinnati Reds who pitched in 680 innings. Since 1900, the most innings pitched in a season is 464 by Ed Walsh of the Chicago White Sox in 1908. Since 1950, the most innings pitched in a season is 376 2/3 by Wilbur Wood of the Chicago White Sox in 1972.
