A doubleheader, which consists of seven innings each game, is usually sufficient.

Further, Managers may opt for additional innings depending on the situation.

Tie in Regulation Games

If the teams draw even after the last inning, managers will need to request extra innings so that neither team scores more than the other.

Call for Suspension

More incidents could lead to the manager of the home side team calling for suspension and reducing the number of innings.
