Banana Ball rule

Banana Ball designated hitter and extra hitter rule

Lineups have ten spots, including both a designated hitter and an extra hitter.

The details

If the designated hitter moves into the field, they keep their batting spot but the pitcher bats in place of the replaced fielder.
The extra hitter can move in and out of the field at any time, swapping spots with a fielder.
