Roster Rules - The 25 man roster

Each team has both a 25 man roster, and a 40 man roster. I'm going to start with discussing the 25 man roster today.

The 25 man roster is also known as the active roster. These, simply put, are the players you can use in a live game. Any player that you wish to use MUST be on the active roster. The key with this roster is this: If you wish to have a player available to play, you must get them on this roster. There are a few ways to get players onto it:

- Place a player on the disabled list (either 15 or 60 day)
- Release a player
- Send a player to the minor leagues (on an option)

Any player that a team wishes to use in a playoff game must also be on the 25 man roster as of August 31st each year.

All players which are on the 25 man roster are automatically on the 40 man roster as well.
