Active, expanded, and postseason rosters
As of the 2022 season, each Major League Baseball team maintains a 26-man active roster, a 28-man expanded roster, and a 40-manTrades
Teams may trade only players currently under contract. Trades between two or more major-league teams may freely occur at any time during a window that opens two days after the starting date of the final game of the most recent World Series and closes at 4 pm Eastern Daylight Time (UTC 2000) on July 31. MLB had allowed trades during the month of August if players cleared waivers, but August trades involving players on a team's 40-man reserve list were eliminated after the 2018 season per the Official Major League Rules, 9(b)(3). Unlike in theWaivers
Any player under contract may be placed on waivers ("waived") at any time. Before the abolition of August trades in 2019, teams were ''required'' to place any player they wished to trade after MLB's July 31 trade deadline on waivers before trading him. If a player is waived, any team may claim him. If more than one team claims the player from waivers, the team with the weakest record in the player's league gets preference. If no team in the player's league claims him, the claiming team with the weakest record in the other league gets preference. In the first month of the season, preference is determined using the previous year's standings. If a team claims a player off waivers and has a viable claim as described above, his current team (the "waiving team") may choose one of the following options: * arrange a trade with the claiming team for that player within two business days of the claim; or * refuse the claiming team's request and keep the player on its major league roster, effectively canceling the waiver; or * do nothing and allow the claiming team to do three things: assume the player's existing contract, pay the waiving team a waiver fee, and place the player on its active major league roster. If a player is claimed and the waiving team exercises its rescission option, the waiving team may not use the option again for that player in that season—a subsequent waiver would be irrevocable with a claiming team getting the player essentially for nothing. If no team claims a player off waivers after three business days, the player has cleared waivers and may be assigned to a minor league team, traded (to any team), or released outright. The waiver "wire" is a secret within the personnel of the Major League Baseball clubs; no official announcement of a waiver is made until a transaction actually occurs, although information sometimes leaks out. Before the abolition of post-July 31 trades, players were often waived during the post-July "waiver-required" trading period for teams to gauge trade interest in a particular player. Usually, when the player was claimed, the waiving team would rescind the waiver to avoid losing the player unless a trade could be worked out with the claiming team. The National League (NL) was the first of the two major leagues to adopt the trade deadline rule in 1917. Originally it was enforced after June 15, but was later changed as the result of a new collective bargaining agreement. For many years, players could not be traded from one league to another without being waived by all of the teams in the trading team's league. Then an inter-league trading period was established, centered on the winter baseball meetings in December. Later, there were two "inter-league" trading periods each year, one from after the World Series until mid-December and the second from a week beforeAssignment to a minor league team
Options
Options are directed by MLB Rule 11 (C). A player has a finite number of option ''years'' in which he may be moved between the major and minor leagues up to five times as of 2022; previously, a player could be optioned an unlimited amount of times subject to the 15 day wait period for pitchers and two-way players and 10 day wait period for hitters except when either the "27th man" or injured list exception applied. If a player is on the 40-man reserve list but not on the active major league roster, he is said to be on optional assignment—his organization may freely move him between the major league club and the minor league club. The rules for this are as follows. (In all cases, an assignment of a player on a major-league injured list to the minors while on a rehabilitation assignment does not count as time spent in the minors.) * Once a player has been placed on a team's 40-man reserve list, a team has 3 option years on that player. ** A player is considered to have used one of those three option years when he spends at least 20 days in the minors in any of those 3 seasons. * A team may have a fourth option year on a player with less than five full seasons of professional experience, provided that both conditions below are met. *# A player has not spent at least 90 days on an active professional roster in a season. Minor leagues that play below Class A Advanced have seasons that are shorter than 90 days, and as such, any player who spends a full season in a rookie or Class A (short-season) league will receive a fourth option year. *# A player has not spent at least 60 days on an active professional roster AND then at least 30 days on an injured list in a season. Only after 60 days have been spent on an active professional roster does time spent on the injured list count towards the 90-day threshold. As with the prior example, this cannot occur with players who spend a full season in a rookie or Class A (short season) league. Per the current collective bargaining agreement between MLB and the Players Association, effective as of the 2022 season, a player may be optioned to the minor leagues no more than five times in a given season. Once a player is optioned to the minors (except if recalled to serve as the "27th man" for a doubleheader), a player cannot be recalled to the majors for 10 days (if a position player) or 15 days (if a pitcher or two-way player) unless another player is placed on the injured list and a recall is to replace that player. Once all of the options have been used up on a player, a player is considered "out of options" and a player must be placed on and clear waivers prior to being sent down to the minor leagues (there is also the "veterans' consent" rule). The option system was designed to prevent players from being buried in the minor leagues forever, by forcing teams to make a decision within a limited number of years on whether or not they can use a player in the Major Leagues. Once placed on the protected 40-man reserve list the player knows his team will have to bring him up to the majors, or expose him to being claimed on waivers so that another team can bring him to the majors, all within three years. Options do not "reset" if a player is traded - he still has only the original three option years that began when he was first placed on a team's 40-man reserve list.Designated for assignment
A player who is designated for assignment (DFA) is immediately removed from the 40-man reserve list. This gives the team time to decide what to do with the player while freeing up a roster spot for another transaction, if needed. Once a player is designated for assignment, the team has seven days (it had been 10 days under the 2012–2016 Collective Bargaining Agreement) to do one of the following: the player can be traded, the player can be released, or the player can be put on waivers and, provided he clears, outrighted to the minors. A player who is outrighted to the minors is removed from the 40-man reserve list but is still paid according to the terms of his guaranteed contract. A player can only be outrighted once in his career without his consent.Veterans' consent
If a player has 5 years of major-league service, he may not be assigned to a minor-league team without his consent. This exclusion applies regardless of whether he has not yet been outrighted once, has remaining options, or has cleared waivers. If the player withholds consent, the team must either release him or keep him on the major league roster. In either case, the player must continue to be paid under the terms of his contract. If he is released and signs with a new team, his previous team must pay the difference in salary between the two contracts if the previous contract called for a greater salary.Injured list
If a major league player cannot play because of a medical condition, he may be placed on the 10-day injured list (IL) (15 days prior to the 2017 season; to be changed back to 15-days beginning the 2020 season). This removes the player from the 25-man roster, freeing up a space, but the player is ineligible to play for at least 10 consecutive days. Players on the 10-day injured list are still a part of the 40-man roster. An injured player may also be placed on the 60-day injured list to remove the player from the 40-man roster as well, with the condition of being ineligible to play for at least 60 consecutive days. In 2011, a 7-day injured list was added specifically for players who have suffered a concussion. This was instituted to allow players who may recover from their concussions quickly to be removed from the active roster and replaced for a shorter period of time than the standard IL term. A player who is still suffering from concussion symptoms at the 7-day mark is automatically transferred to the 10-day IL. Both the brain injury and the player's recovery need to be verified by team and league doctors; the list is not intended for non-concussion injuries. Players placed on the 7-day or 10-day injured list may be moved to the 60-day injured list at any time, but not vice versa. Players may be placed on any injured list retroactively for a maximum of 5 inactive days and may remain on either list for as long as required to recover. During this 5-day period, a player's status is said to be day-to-day, indicating that the team is in the process of deciding whether the player must be placed on either IL or is healthy enough to return to active service. Injured players may not be traded without permission of the Commissioner nor may they be optioned to the minors, though they may be assigned to a minor league club for rehabilitation for a limited amount of time (30 days for pitchers, 20 for non-pitchers). Until 2018, the injured list (IL) was called the disabled list (DL). MLB changed the name of the disabled list to the injured list beginning the 2019 season.Personal leave
Bereavement list
The bereavement list may be used when a player finds it necessary to leave the team to attend to a serious illness or death in his (or his spouse's) immediate family. A player placed on the bereavement list must miss a minimum of three games and a maximum of seven games. The team can use another player from its 40-man roster to replace a player on the bereavement list.Paternity leave list
The paternity leave list may be used when a player chooses to leave the team to attend the birth of his child. A player placed on the paternity leave list must miss the next team game, but no more than three games. The team can use another player from its 40-man roster to replace a player on the paternity leave list. This list was adopted beginning with the season.Rule 5 draft
If a player not on a 40-man reserve list has spent four years with a minor-league contract, originally signed when 19 or older or five years when signed before the age of 19, he is eligible to be chosen by any team in the rule 5 draft during the offseason. No team is required to choose a player in the draft, but some do. If chosen, the player must be kept on the selecting team's 26-man major league roster for the entire season after the draft—he may not be optioned or designated to the minors. The selecting team may, at any time, waive the rule 5 draftee, such as when they no longer wish to keep him on their major league roster. If a rule 5 draftee clears waivers, he must be offered back to the original team, effectively canceling the rule 5 draft choice. Once a rule 5 draftee spends an entire season on his new team's 26-man roster, his status reverts to normal and he may be optioned or designated for assignment. To prevent the abuse of the rule 5 draft, the rule also states that the draftee must be active for at least 90 days. This keeps teams from drafting players, then "hiding" them on the injured list for the majority of the season. For example, if a rule 5 draftee was only active for 67 days in his first season with his new club, he must be active for an additional 23 days in his second season to satisfy the rule 5 requirements. Any player chosen in the rule 5 draft may be traded to any team while under the rule 5 restrictions, but the restrictions transfer to the new team. If the new team does not want to keep the player on their 26-man roster for the season, he must be offered back to the team he was on when he was chosen in the draft. The intent of the rule 5 draft is to prevent teams from holding major league-potential players in the minor leagues when other teams would be willing to have them play in the majors. However, this draft has also become an opportunity for a team to take a top prospect from another team who might not be ready for the major leagues. For example,See also
