How Many Innings Are in a College Baseball Game? 7 or 9?

how many innings are in a college baseball game

The first thing you should know about baseball is that it 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 are in a college baseball game? For your information, collegiate games typically last 9 innings, which is similar to a Major League game. However, there are variations due to rule updates and game conditions. Read on to know the details.

College Baseball Innings Per Game

The National Collegiate Athletic Association (NCAA) dictates the number of innings in an official baseball game, which is 9 innings.

The question is, is college baseball 9 innings always the case? As expected, the answer is no, since when are baseball rules that simple?

Here’re some variations of inning counts in baseball games of different leagues and situations:

While the MLB has 9 innings in its doubleheader games, minor league and college league play 7 innings only. This rule for 7-inning doubleheaders is applicable to postseason games, too.

A doubleheader simply means two teams will have a rematch on the same day. Before 2021, both games would have 9 innings like any official one. The regulation was changed to 7 innings due to Covid and then reversed back to 9 once pandemic restrictions became less of a worry.

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

The most innings in a college World Series baseball game ever played were 15 innings. The two teams that made history were The Virginia Cavaliers and TCU Horned Frogs, who played for about 4 hours and 51 minutes.

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

There was only one special occasion where this rule did not apply. Because LSU’s Alex Box Stadium could not accommodate official 9-inning games due to severe rain, certain games in the 1991 tournament had to be shortened to seven innings.

What Are the Mercy Rules in College Baseball?


The Mercy rule is one of the rules that shortens a baseball game. It’s employed when one team leads by ten runs or more after the seventh inning of a nine-inning game or after the fifth inning of a seven-inning game.

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

Here’re some of the usual circumstances where this rule is applicable for college baseball games:

Can College Baseball Play Indefinite Innings?


The answer is yes.

College baseball games, like Major League and minor league games, can go for indefinite innings. It means that if the final inning ends in a tie, the two teams can continue to play extra innings.

There is no regulation that limits the inning until the tie is broken; therefore, the two teams can play until one of them wins.

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.
