Several factors may affect the duration of any inning. These factors are the at-bats numbers, the pitcher’s pace, modifications in pitching, etc. Each team has to take three outs in an inning, totaling six outs per inning.

A typical baseball league and collegiate game comprise nine innings. High school baseball matches run for seven innings. The pitching team has to take three outs within an inning.

Assuming a typical baseball going for 3 hours, each inning will be played for approximately 20 mins (3 hours = 180 mins/9 innings). But to end an inning, each team has to take out three players from their opponent. If they fail so, the innings can go on for an indefinite time.


The Number of Innings in a Baseball Game

A total of nine innings are played in a professional baseball game. An extra inning is played if the score reaches a tie. A game may be truncated at the top half of the ninth inning if a team has scored more than its opponent.

The number of innings in an MLB postseason or World Series doesn’t differ. They are nine innings played for both. The only difference is when the game is stopped due to rain or another calamity.

After rainfall, in the case of the regular season, the game concludes with a winning team; whereas, in the postseason or world series, the game will continue the next day.

An All-star game also comprises nine innings. However, if the scores tie, no extra inning will be played. Instead, the winning team will be decided by Home Run Derby. Three batters will participate based on the manager’s selection. These batters will be awarded three swings. The one that scores the highest will be declared the winner.

Top of the Inning

In the top of an inning, the visiting team bats while the home team pitches and defend.

Middle of the Inning

In the middle of an inning, a pitching shift happens between the teams. After three outs recorded by the home team, roles change. The at-bat visiting team takes on pitching while the home team bats. The middle of the inning awards an opportunity for players to warm up for around 1-2 minutes.

Bottom of the Inning

Home team batting happens in the bottom of the inning. The home team gets an advantage by batting at last, even in extra innings. That’s why the home team must win by taking advantage of the home ground.

Ninth Inning

The ninth inning is the last phase of MLB baseball games. If a score reaches a tie during this inning, the teams are awarded an extra inning to decide the game’s fate.

Sometimes, the bottom of the ninth inning may be skipped. Or it terminates before recording three outs. The game will end in the ninth inning if the following possibilities are met.

  1. If the home team is leading during the end of the top half.
  2. If the home team lags behind or the score is tied at the end of the top half. Later the home team scores more points than the visiting team before the opposing team records three outs at the bottom of the inning.
  3. If the visiting team leads at the end of the inning after recording three outs during the bottom half of the ninth inning.
