If an unsigned player on an MLB Reserve List (40-man roster) is not tendered a 2019 contract by 8 PM (Eastern) on this coming Friday (November 30th), the player will be 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.
NOTE: The MLB contract tender deadline is normally December 2nd, but it is moved up to December 1st if December 2nd falls on a Saturday (as was the case last year), or to November 30th if December 2nd falls on a Sunday (which is the case this year).
