A standard professional baseball game consists of nine innings. Each inning is divided into two halves: the top and the bottom. The visiting team bats in the top half, and the home team bats in the bottom half. If the score is tied after nine innings, extra innings are played until one team leads at the end of an inning. Some youth and amateur leagues may have fewer innings, such as six or seven. In summary:
- Professional games typically have 9 innings.
- Each inning has two halves (top and bottom).
- Extra innings are played if the score is tied after 9 innings.
- Youth and amateur leagues may have shorter games with fewer innings.
This is the general and official structure of baseball innings.
