Baseball Innings

Innings played affect the length of the baseball games. This is why the MLB extra innings rule exists and determines how many extra inning in MLB are played. The baseball length of game may vary depending on occurrences during play. We will dive deeper into the topic below!

What is an Inning in Baseball?

A game is made up of two teams, each with nine innings in which each team attempts to score runs. During an inning, one player from the batting team will be sent to bat, and is referred to as an ‘at bat‘. The pitching team will have nine players out fielding, to try and stop the batter from scoring.

The inning isn’t over until three batters are ‘out’, and if the score is tied at the end of nine innings, the game continues into extra innings until one team is ahead.

How Long is a Baseball Inning?

The duration depends on the number of at-bats, pitching changes, and the pace of the pitcher. An inning lasts for a total of six outs, equating to three per team. In theory, an inning could last indefinitely if the fielding team doesn’t record three outs.

The innings are split into two halves, with the away team batting during the top half of the inning, and the bottom half being batted by the home team. During an MLB game, if the score remains tied at the end of nine innings, the game continues and further innings are played until one team has acquired more runs than the other.

So how long does a baseball game last overall? Generally, the baseball length of the game will last around three hours, but this can depend on the number of innings, as well as other factors that may interfere with the game.

A baseball game lasts around three hours on average and contains nine innings. There is no time limit on an inning, and some don’t make it to the 9th inning.

Different Types of Inning in Baseball

Baseball inning consist of five different types:

Top of the Inning

The top of the inning is played by the away team and isn’t over until three batters have been outed.

Middle of the Inning

The middle of the inning is used as a transition period between the top and bottom inning. During this time, players can change their gear and get ready for the swap over. This period usually lasts between two-three minutes.

Bottom of the Inning

Now that both teams are ready, the home team will take their turn at batting, whilst the away team field and try to stop them from scoring any runs during the inning.

9th Inning

The 9th inning is the end of the game, in most situations. There are circumstances where the 9th inning isn’t completed before three outs take place. According to the 9th inning baseball rules, if the home team is in the lead at the top of the 9th inning, or if the away team is in the lead at the bottom of the 9th inning, the game is over and play will stop.

Extra Innings

By the 9th inning, if the results are tied, extra innings will be used to allow each team to continue batting until there is a winner.

How Many Outs are There in An Inning?

A full inning will consist of six ‘outs’, three from each team, and there are many ways for a player to be caught out.

Different Types of Outs


A batter is out if the pitcher can throw three strikes, also known as being ‘struck out’. The pitcher aims for the ‘strike zone’ when they throw the ball. The strike zone is over the ‘home plate’, below the midpoint of the batter’s waist and shoulders, and above their knees. If the batter swings at a pitch but misses, this is also considered a strike.

Fly Out

A batter is ‘flied out’ when they hit the ball and, without the ball bouncing, a fielder catches it to stop the batter from achieving reaching a base.

Force Out

A runner is forced out when the fielding side touches him with the ball whilst he isn’t standing on a base. This can also happen without touching the runner if the fielder touches the base while the runner is moving.

Tagged Out

A batter must try to put the ball into play by hitting it in front of first or third base, known as inside the foul lines, and must run to first base without being tagged out. If the player is not at the base then he gets tagged out if anyone from the defensive team touches him, with the ball in hand.

The runner is Out of the Baseline

 The Official Baseball Rules state that if a runner runs more than three feet away from his base (to avoid being tagged) then the runner is declared ‘out of the baseline’. The exception is if the runner is trying to avoid interference with a fielder who is fielding a batted ball.


Interference is when a runner or batter tried to change the course of a play. This rule is extremely extensive as it includes the following:

Offensive interference
Verbal interference
Umpire’s interference
Catcher’s interference
Spectator interference
