Adding Players to MLB Reserve List

Only players on an MLB Reserve List (40-man roster) can be placed on an MLB Active List (25-man roster).

A free-agent with prior MLB and/or minor league service who signs a Major League contract must be added to his club's MLB Reserve List (40-man roster) when he is added to an MLB Active List or when the contract is filed with the MLB Commissioner (whichever comes first). Contracts must be filed with the MLB Commissioner within 20 days of signing.
