College baseball games are typically played with nine innings, which is the standard length encouraged by the NCAA for most regulation games

. However, the number of innings can vary depending on specific circumstances:

• Standard games: Usually nine innings.
• Doubleheaders: Games can be shortened to seven innings to manage player fatigue and scheduling; options include two nine-inning games, one nine-inning and one seven-inning game, or two seven-inning games

• Mercy rule: Some games may end early (after seven innings) if one team leads by at least 10 runs, though this rule is not applied in NCAA tournament games

• Extra innings: If the score is tied after nine innings, the game continues with extra innings until one team leads at the end of an inning, potentially extending indefinitely

• Weather-shortened games: If at least five innings are completed but weather prevents continuation, the game may be considered official and ended early with the current leader declared the winner

In prestigious events like the College World Series, the traditional nine- inning format is maintained to preserve the full competitive depth of the game

. In summary, while nine innings is the norm for college baseball, variations to seven innings or extra innings occur based on doubleheaders, mercy rules, ties, or weather conditions.
