How Many Innings In Baseball?

The simple answer is…there are 9 innings in a Major League Baseball (MLB) game. Right? Yes. And sometimes no.

In professional leagues across the United States, baseball games last 9 innings per game. The game will go into extra innings in rare cases where both teams are tied after 9 innings. In some cases, when the weather is too dangerous to continue a game it is considered a full game if the visitors have completed the 5th inning (15 outs).

Let’s explore how the innings in baseball work.

How Many Innings In High School Baseball?

High School baseball does not play a full 9 innings. Teenagers’ arms are still too young to play longer than 7 innings. While that is not a huge difference from professional leagues, it gives high school baseball players a chance to start adapting to longer nine-inning games

How Many Innings In College Baseball?

College baseball has millions of viewers across the country. The game’s length is the same as a professional game.

College baseball games are nine innings, and the same rules apply to college baseball as in the MLB. These rules can include the mercy rule (or the ten-run rule) and what happens if a game is tied.

How Many Innings In Little League Baseball?

Little League baseball is played by kids between the ages of 9 and 12. The field they play on is often a lot smaller than other leagues. Another significant difference is the number of innings in a game.

While some Little League associations differ, most stick to the six-inning format. However, the rules that dictate whether a game would be stopped and what happens in a stoppage are much more lenient for Little League than others.

How Long Is One Inning In Baseball?

A baseball game is quite long (over 3 hours on average). Each inning can last anywhere between 15 to 25 minutes or longer. This applies to almost any league, from Little League to professional leagues. In professional baseball, there is a 2-minute break between each inning. This can change depending on the league.

Can Baseball End Before 9 Innings?

A baseball game can end before nine innings, but this is one of the most complicated topics to cover when discussing baseball’s regulations. Let’s take a look at a few reasons why a baseball game could be stopped early:

  • The Mercy Rule (ten-run rule) (Youth Leagues only)
    • The rule states that the game is over if a team is ahead by ten or more runs after five innings
  • Poor weather conditions.
  • Problems with the pitcher’s mound (any level)
  • Inadequate lighting (lower-level leagues)
  • Medical emergencies

It is very rare for a baseball game to be stopped, so while I listed only a few reasons, it is essential to remember that any issues need to be significant for a stoppage to take place. That said, a few complicated rules come into play when a baseball game is stopped.

  • After five innings, if one team is ahead, the game will be called “Regulation.” The leading team will win if the game ends before nine innings.
  • The game is tied if the game ends before five innings and no team is ahead.
  • If a team is ahead and the game ends before five innings, the game is suspended for a later date.

What Happens If The Game Is Tied After 9 Innings?

A game can go into extra innings if there is no winner after the regulatory 9. Extra innings last around the same time as any other inning in baseball.

The game will be played until there is a clear winner unless the game is stopped for other reasons.

It can take an exceptionally long time to reach a winner in a baseball game. Theoretically, there are no limitations to how long a baseball game can carry on. Extra innings could last less than an hour or take longer than the game itself.

How Many Outs Per Inning Are There In Baseball?

In baseball, an inning is divided into two halves: the top and the bottom. In an inning, each team has a chance to bat and pitch. Once a team gets three outs, their half ends.

Three outs multiplied by nine innings gives a total of 27 possible outs that each team can get in a full match.

When you add each team’s outs together, each inning consists of six outs, totaling 54 outs per match.


Now that you know the rules about baseball innings, watching or playing the game should be a little bit easier. While baseball is one of the more complicated sports in terms of rules and regulations, reading through articles like this will help you better understand what is happening.
