Roster Status of Signed & Unsigned Players on MLB Reserve List

After the conclusion of the MLB season, only those players on a club's MLB Reserve List (40-man roster) who have contracts for the following season are considered "signed players," but the other players on the 40-man roster are still under club control (they are "reserved").

Unsigned players on an MLB club's Reserve List (40-man roster) would include any player who was added to an MLB Reserve List (40-man roster) after the conclusion of the MLB regular season, any player who can have his contract unilaterally renewed by his club, any player who is eligible for salary arbitration, and any player eligible to be an MLB free-agent per Article XX-B of the CBA.
