How Many Innings In A Major League Baseball Game?

The average major league baseball game lasts about three hours. There are nine innings in a game, and each team has a chance to bat in each inning.


In baseball, innings are the basic units of play. In a typical major league game, each team bats until three batters are “out,” meaning they fail to reach base safely. Once both teams have batted in the same inning, it is complete. The score at the end of an inning is known as the “inning score.” A game typically consists of nine innings, but some games go into “extra innings” if the score is tied at the end of nine innings.

The History of the Length of a Baseball Game

The length of a baseball game has varied throughout the sport’s history. Early games were often much shorter than today’s games, sometimes lasting only an hour or so. By the late 1800s, however, the average game had increased to around nine innings.

This remained the standard until 1960, when teams began to play longer games. In 1968, Major League Baseball decided to increase the length of games from nine innings to ten. This rule change lasted just one season before being rescinded.

Since then, the length of a baseball game has fluctuated depending on various factors such as league regulations or competitive situations. On average, however, a major league game now lasts about three hours.

The Current Length of a Baseball Game

The current length of a baseball game is nine innings. Each team gets three outs per inning, with a total of 27 outs in the game. If a team is ahead by more than seven runs after seven innings have been played, or if a team is ahead by more than 10 runs after nine innings have been played, that team is declared the winner. If the score is tied after nine innings, extra innings are played until one team has a lead and can declare itself the winner.

Why the Length of a Baseball Game Has Changed Over Time

The length of a baseball game has varied greatly over the sport’s history. In the early days of baseball, games often lasted over three hours. As the sport has evolved, however, the length of games has decreased significantly. The average Major League Baseball game now lasts around two and a half hours.

There are a number of reasons why the length of a baseball game has changed over time. One of the most significant factors is the introduction of new rules and regulations. In recent years, Major League Baseball has instituted a number of changes designed to speed up the game. For example, in 2020, a new rule was introduced that requires relief pitchers to face at least three batters before they can be taken out of the game. This rule alone has helped to reduce the length of games by around five minutes.

Another factor that has contributed to shorter baseball games is the increased use of technology. In particular, instant replay review has helped to speed up the game by reducing the amount of time that is spent arguing calls on the field. In addition, newer stadiums are often equipped with advanced drainage systems that help to reduce delays caused by rainouts.

Ultimately, though, the biggest reason why baseball games are shorter now than they used to be is simply because fans prefer it that way. With so many other entertainment options available, most fans don’t want to spend more than two or three hours watching a baseball game. As a result, teams have been forced to adapt and shorten their games in order to keep fans engaged.


The average major league baseball game lasts just over three hours. However, there is no set number of innings in a game. The number of innings varies depending on the league, the level of competition, and the rules of the specific game. In general, professional games have nine innings, while amateur games have seven innings.
