How many innings in college baseball

Baseball is played in innings. Baseball, like other sports that determine playing time in turns, allows teams to alternate between defense and offense in each inning.

So, how many innings in college baseball? 7 or 9? Collegiate games typically last 9 innings, which is comparable to a Major League game. However, there are differences due to rule changes and game conditions. Read on to find out.

How many innings in college baseball

To understand how many innings are in a college baseball game, you must first understand the nature of doubleheaders, influential rules such as the 10-run rule, the overall nature of the baseball game, and a variety of other factors.

Once you’ve grasped these concepts, you’ll be able to easily appreciate, participate in, and analyze a college baseball game or a minor league baseball game in general.

Also, knowing the number of innings in a college baseball game will help you set your expectations for the game.

A single game in a day is usually nine innings long, while two games in a day (a “doubleheader”) are usually two seven-inning games.

Following that, a “mercy rule,” such as a “10-run rule,” a “15-run rule,” and/or a “20-run rule,” may be in effect, causing the game to end 2, 4, and 6 innings earlier than the originally-scheduled regulation number of innings, respectively. Due to a lopsided score and the lack of probability, the losing team could make such a dramatic comeback.

And, as is customary in baseball, if a game is tied after the final regulation inning, it can go into an indefinite number of extra innings.

It’s also worth noting that any game at any level could be called off early due to weather, curfew (where applicable), or any other unforeseen event and be considered “complete” or “suspended” to be finished later.

Read on to have a detailed explanation of the above.

Variations of inning counts in baseball games of different leagues and situations

In baseball games of various leagues and situations, inning counts vary.

Innings in college baseball doubleheader

While MLB doubleheader games last 9 innings, minor league and college league games last only 7 innings.

This rule applies to postseason games as well as 7-inning doubleheaders.

A doubleheader simply means that two teams will play again on the same day. Before 2021, both games would be 9 innings long, just like any other official game. Because of Covid, the regulation was changed to 7 innings.

Innings in College World Series Games (CWS)

The number of innings in the CWS will be the same as the NCAA’s official rules, which are nine.

The most innings ever played in a college World Series baseball game was 15. The Virginia Cavaliers and TCU Horned Frogs made history by playing for approximately 4 hours and 51 minutes.

Innings in SEC baseball

If you’ve ever heard of or planned to watch the Southeastern Conference Baseball Tournament (SEC), you should know that these games between collegiate teams also last 9 innings.

There was only one time when this rule did not apply. Due to severe rain, LSU’s Alex Box Stadium could not accommodate official 9-inning games, so certain games in the 1991 tournament were shortened to seven innings.

Number of innings in a college baseball game

Typically, a college baseball game lasts seven innings. However, the National Collegiate Athletic Association (NCAA) recently established a standard for an official game, allowing for seven to nine innings.

However, the number of college baseball innings may vary depending on whether one or two games are played in a day.

One game lasts nine innings, whereas two games (or the doubleheader) last only seven innings each.

If a tie occurs in the final inning, a game or two may go beyond their scheduled innings (for regular conference matches).

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

How Does the Mercy Rule Apply in College Baseball?

The Mercy rule is one of the rules that shortens a baseball game.

The mercy rule requires one team to lose a game whenever the opposing team builds a 10-run lead after the seventh inning. When the game is previously set to seven innings, the rule takes effect earlier. It becomes valid in this case during the fifth inning.

The game can be called in this circumstance, and the leading team wins without having to play the final two innings.

Only when the following conditions exist in a college baseball game does the mercy rule apply:

  • 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 league baseball game can last indefinitely. These innings are not restricted by any rules.

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

Consider how long that took. To put that into perspective, the historic college baseball event at Salisbury University lasted approximately 6 hours and 30 minutes. That is some game!

What is the Longest College Baseball Game?

In college baseball history, the record for the game with the most innings occurred in a tournament in 2021.

Twenty-three innings were played in the game between the Sea Gulls and Southern Virginia, taking about 6 hours and a half. It is also the longest game in D3 college baseball.

The game between Boston College and Texas University in May 2009 is renowned as the Division I Championship’s longest college baseball game. It lasted 25 innings and took roughly 7 hours to determine the winner.

The impressive DII baseball league record belongs to a game between Omaha and Morningside with 19 innings.

How is the number of innings in a college baseball game determined?

The number of innings in a college baseball game is determined by several factors.

These factors are as follows:

1. Conditions Under the Mercy Rule

Most of the time, the mercy rule shortens the game to accommodate conference scheduling constraints.

2. Call for a Doubleheader

If the decision is made to play a single game or a doubleheader, the number of innings changes accordingly.

Normally, a doubleheader per day with seven innings per game would suffice. However, depending on the circumstances, managers may elect to play extra innings.

3. Tie in Regulation Games

A regulation game is one that lasts until the seventh or ninth turn. However, if both teams are tied after the final inning, the managers must call for extra innings until one team scores more than the other.

4. Suspension Request

Weather conditions and imposed curfew, darkness due to the absence of field lights, and numerous other incidents should compel the home team’s manager to call for suspension, reducing the number of innings.

5. The overall dynamic between teams

The synergy, levels, and overall pitching abilities of the players on each team either lengthen or shorten the innings.

Professional-level skills are supposed to shorten inning length and numbers, whereas rookie skills are supposed to lengthen them.

What Justifies a Seven or Nine-Inning Game?

According to the NCAA, the ninth inning is the official length of a college baseball game.

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

  1. In a non-conference tournament, two teams have separate doubleheader schedules.
  2. It’s the final day of an intra-conference game series (also known as “Sunday”).

What are the other college baseball game rules?

There is no single rule that applies to all college teams. The number of innings in a college baseball game is entirely determined by the school’s rules and policies, the availability of facilities and equipment, and the health and weather conditions.

NCAA’s approval could be a deciding factor. When NCAA supports a game, the school will support its students by giving them some leeway on exams and homework.

It is up to the school administration, parents, and NCAA representatives whether a college baseball game takes several hours or a full day to complete. Everything comes down to what everyone has agreed on.

One thing is certain in all of this arbitrariness. A college baseball game is a serious undertaking. Unlike little league or high school baseball, semi-professional league advancements, higher stakes, and investments are covered by the former.

Because of the significant investment, even schools would prefer to focus on a baseball game within a day or two.

So why not? After all, we are talking about baseball here.


So, how many innings in college baseball? It is either seven or nine innings. Depending on the skill and dynamics of the teams’ players, each game can take up to three hours to complete.

The official number of innings in college baseball, according to the NCAA, is nine. However, the regulated nine-inning can increase or decrease due to circumstances, exceptions, interpretations, rules, and other interruptions in an inter-conference event.
