A standard college baseball game is 9 innings long, just like Major League Baseball.

However, there are a couple of important wrinkles:

  • Some games can end after 7 innings in specific situations, such as:
    • Certain scheduled doubleheaders where each game is set for 7 innings.
* “Run-rule” or **mercy rule** situations in some conferences, where a team leads by a large margin (often 10+ runs) after 7 innings.

If the game is tied after 9 innings, college baseball uses extra innings , and teams keep playing full innings until one team leads at the end of an inning.

So in simple terms:

  • Regulation college baseball game: 9 innings.
  • Sometimes shortened to 7 innings (doubleheaders or mercy rule).
  • Can go to extra innings if tied after regulation.
