This Wednesday is the non-tender date for Major League Baseball teams. Essentially, players who have not yet reached free agency, but are on the 40-man roster must be either tendered a contract for the next season, or non-tendered. If a player is tendered a contract, then they will either be paid the minimum based on their service time, or they will head to arbitration (or be offered a deal by the team which they can agree to or choose to head to arbitration) to determine their salary for the upcoming year. Non-tendered players become free agents.
For the Cincinnati Reds there are a lot of players that are eligible to be non-tendered.
