Tendering Contracts to Unsigned Players on MLB Reserve List
If an unsigned player is not tendered a contract on December 2nd (or December 1st if December 2nd falls on a Saturday, or November 30th if December 2nd falls on a Sunday), the player is said to be "Non-Tendered," he is immediately removed from his club's MLB 40-man roster, and he becomes an unrestricted free-agent, free to sign a major league or minor league contract with any club, including the club that non-tendered the player. A "Non-Tendered" player receives no termination pay, and the player's former club receives no compensation if the player subsequently signs with another club.
Each unsigned player on an MLB 40-man roster who is tendered a contract must be offered at least the MLB minimum salary ($500K) and (with a couple of exceptions) at least 80% of the player's previous season's salary, and at least 70% of the player's salary from two seasons back.
Some players have a "minor league split" salary in their contract which they are paid if they are sent to the minors. In most cases, a player's minor league "split" salary must be at least 60% of the player's salary from the previous season. The one exception is if a free-agent signs a major league contract with a minor league "split" salary, the "60% rule" does not apply
The minor league "split" minimum salary is $40,250 for players who are on an MLB 40-man roster for the first time, and a minimum $80,500 for all other players.
