40-man Roster

Definition

Note: As part of MLB's health and safety protocols during the COVID-19 pandemic, each club will have a 30-man roster for the first two weeks of the 2020 season, 28 for the next two weeks, and 26 for the remainder of the season. Teams will submit 60-man pools -- that is, the group of players who will be able to play for them this season. According to the league's Operating Manual, all players on a 40-man roster "that the club anticipates participating" during the season will be part of the player pool, while the rest will be made up of non-40-man roster players under contract. Each team will be permitted a three-player taxi squad for every road trip, giving them immediate options to replace an injured or COVID-19 infected player. There will be no limit on the number of pitchers on the active roster, or on position players pitching. Rather than a 10-day injured list for position players and 15-day injured list for pitchers, there will be a 10-day injured list for all players in the shortened season. The 60-day injured list will be reduced to 45 days. The 7-day injured list will be unaffected. There will also be a COVID-19 injured list with no minimum or maximum number of days per trip.

In a typical season, the 40-man roster includes a combination of players on the 26-man roster (it was 25, prior to 2020), the 7-, 10- and 15-day injured lists, the bereavement/family medical emergency list and the paternity leave list, as well as some Minor Leaguers.

In order for a club to add a player to the 26-man roster, the player must be on the 40-man roster. If a club with a full 40-man roster wishes to promote a Minor League player that is not on the 40-man roster, it must first remove a player from the 40-man roster -- either by designating a player's contract for assignment, trading a player, releasing a player or transferring a player to the 60-day injured list.

A player who is on the 40-man roster but does not open the season on the 26-man roster must be optioned to the Minor Leagues. Once a player has spent at least 20 days in the Minors on an optional assignment, one of his options is expended for that season. Only one Minor League option is used per season, regardless of how many times a player is optioned to and from the Minors over the course of a given season. Players typically have three option years, although a fourth may be granted in certain cases. Out-of-options players must be designated for assignment -- which removes them from the 40-man roster -- and passed through outright waivers before being eligible to be sent to the Minors.

The 40-man roster is an important distinction in the offseason, as players who are on the 40-man roster are protected from being selected by another organization in the annual Rule 5 Draft, held each year in December at the Winter Meetings. Players signed at age 18 or younger need to be added to their club's 40-Man roster within five seasons or they become eligible for the Rule 5 Draft. Players who signed at age 19 or older need to be protected within four seasons.
