how many innings are in a college baseball game

To better understand how many innings are in a college baseball game, you have to understand the nature of doubleheaders, influential rules like the 10-run-rule, the overall nature of the baseball game, and many other factors.

Once you understand these factors, you can easily appreciate, participate in, and analyze a college baseball game or a minor league baseball game in general.

Also, knowing how many innings a college baseball game has will eventually set your expectations for the game.


Number of Innings in College Baseball

Normally, a college baseball game takes seven innings to complete. However, the National Collegiate Athletic Association (NCAA) recently set a parameter for an official game, extending seven to nine innings possible.

The number of college baseball innings could change though, depending on whether one or two games occur in a day.

One game takes nine innings, while two games (or better known as the doubleheader) take only seven innings each.

As usual, a game or two could go beyond their expected innings if a tie occurs in the last inning (for regular conference matches).

On the other hand, a game can finish early depending on the decisions surrounding the “mercy rule”.

How Does the Mercy Rule Apply in College Baseball


The mercy rule works by causing one team to lose a game whenever the opposing team secures a 10-run lead after the 7th inning. However, the rule comes into effect earlier when the game has been previously set to seven innings. In this case, it becomes valid during the fifth inning.

When Does the Mercy Rule Usually Apply

The mercy rule applies to a college baseball game only when there are:

  • possible constraints and/or limitations surrounding a conference
  • unexpected events and interruptions in a conference
  • decisions to set a “Sunday game”
  • inabilities to proceed with a doubleheader or indefinite innings
  • limitations in the visiting team’s travel itinerary
  • And many more…

Can College Baseball Games Go for Indefinite Innings


Yes. A college baseball game or a minor baseball game match can go for indefinite innings. No rule limits these innings.

The longest college baseball world series game by innings to date (Southern Virginia University vs. the Sea Gulls) that happened on May 8, 2021 took 23 innings to finish.

Just imagine how long that took. Let us put that into an hourly perspective: the historic college baseball event that took place at Salisbury University took roughly 6 hours and 30 minutes to finish. Now, that’s some game!

What are Other College Baseball Game Regulations

As I mentioned earlier, there is no one rule for all college teams. The limits of innings that set a college baseball game depend entirely on the schools’ rules and policies, the availability of facility and equipment, and the conduciveness of health and weather.

Another determinant perhaps is the NCAA’s nod. Whenever the NCAA backs a game, the school would follow suit in supporting its students by cutting them some slack in the exams and homework.

Whether it takes several hours or a whole day to finish a college baseball game, it is up to the school admin, parents, and the NCAA representatives. It all boils down to what everyone has agreed.

In all this arbitrariness, one thing remains for sure. A college baseball game is a serious business. Unlike the little league or high school baseball, the former covers semi-professional league advancements, higher stakes, and investments.

It is due to that much of an investment that even the schools would choose to focus on a baseball match within a day or two.

And why not? After all, it is baseball that we are talking about here.

What Determines the Number of Innings in a College Baseball Game

Certain factors determine the number of innings in college baseball game.

These factors include:

  • Conditions Under the Mercy Rule: Most of the time, the mercy rule shortens the game to accommodate constraints in the conference schedule.
  • Call for Doubleheader: If decisions to either go for one game or a doubleheader arise, the number of innings changes accordingly.

A doubleheader per day, consisting of seven innings per game, would usually suffice. However, depending on the circumstances, the managers would opt for extra innings.

  • Tie in Regulation Games: A regulation game lasts up to either the seventh or ninth turn. However, when both teams tie after the final inning, the managers will have to call for extra innings until either of the teams score higher than the other.
  • Call for Suspension: Force majeure like weather conditions and imposed curfew, darkness due to the absence of field lights, and many more incidents should compel the manager of the home team to call for suspension, reducing in turn, the number of innings.
  • Overall Dynamic Between Teams: The synergy, levels, and overall pitching skills of the players between teams either extend or shorten the innings. Professional-level skills are supposed to shorten the inning length and numbers; rookie skills, on the other hand, prolong them.

What Calls for a Seven or Nine-Inning Game

As far as the NCAA is concerned, the ninth inning is the official college baseball game length.

However, the manager of the home team can decide and call for only seven innings based on the following exceptions:

  • Two teams in a non-conference tournament have separate doubleheader schedules
  • It is the last day (also known as “Sunday”) of an intra-conference game series.


The answer to the question “how many innings are in a college baseball game” is either seven or nine innings. Each game can take roughly three hours to complete, depending on the skill and dynamics of the players of the teams.

The official regulated inning, according to the NCAA, is a nine-inning game. However, due to circumstances, exceptions, interpretations, rules, and other interruptions in an inter-conference event, the regulated nine-inning can either increase or decrease.
