Post-Season Roster Eligibility

A club's Active List (25-man roster) must be submitted to the MLB Commissioner prior to the start of each post-season series (Wild Card game, LDS, LCS, and World Series).

A club's Active List can be changed (tweaked) prior to the start of each series (WC, LDS, LCS, and WS)

1. A player who received a Prohibited Substance Suspension prior to the start of Spring Training, during Spring Training, during the regular season, or during a post-season series (Wild Card, LDS, LCS, or World Series), is ineligible to play in any MLB or minor league post-season game(s) or series in that season, even if the player has completed serving the suspension.

2. Any player on the Disqualified List, Ineligible List, Voluntary Retired List, or Restricted List as of midnight (Eastern) on August 31st or who is placed on the Disqualified List, Ineligible List, Voluntary Retired List, or Restricted List anytime after midnight (Eastern) on August 31st is ineligible to be included on a post-season Active List that season.

3. All other players on a club's MLB Reserve List (40-man roster), MLB 60-day DL, or Military List prior to midnight (Eastern) on August 31st are automatically eligible to be included on a post-season Active List (25-man roster).

4. A player must remain on his club's MLB Reserve List, MLB 60-day DL, and/or Military List continously throughout the remainder of the MLB regular season and post-season in order to be automatically eligible to be included on a post-season Active List (25-man roster). If a player is sent outright to the minors after midnight (Eastern) on August 31st, he is no longer automatically eligible to be included on a post-season Active List (25-man roster).

5. A player on an MLB club's Disabled List (7-day, 15-day, or 60-day), Bereavement List, Family Medical Emergency List, or Paternity List is eligible to be included on a post-season Active List only after spending the minimum number of days required to be served by a player on that list.

6. An injured post-season eligible player can (with the approval of the MLB Commissioner) be replaced on his club's LDS, LCS, or World Series Active List by a player who was on an Active List, Reserve List, 60-day DL, or Military List of a minor league affiliate from that organization prior to midnight (Eastern) on August 31st, or by a player who was on the club's MLB Reserve List (40-man roster), MLB 60-day DL, or Military List prior to midnight (Eastern) on August 31st but who was subsequently sent outright to the minors. (In the case of a player who is sent outright to the minors after August 31st, the player must remain on a Reserve List of a minor league affiliate from that organization continously throughout the remainder of the MLB regular season and post-season in order to be eligible to replace an injured post-season eligible player).

7. A post-season eligible player who is injured during a post-season series (LDS, LCS, or World Series) can (with the approval of the MLB Commssioner) be replaced during the series by another player, but the injured player is ineligible to be reinstated to his club's Active List (25-man roster) for the balance of that series and the next series (LCS or World Series). Also, a pitcher must replace a pitcher and a position player must replace a position player. However, it is NOT necessary for a catcher to replace a catcher, an infielder to replace an infielder, or an outfielder to replace an outfielder.

8. An injured post-season eligible player who is placed on an MLB 60-day DL after August 1st is NOT eligible to be replaced by a minor leaguer, unless the injured player was already on the club's 7-day DL or 15-day DL on August 1st and then was subsequently transferred to the club's 60-day DL after August 1st.

9. A minor league player who replaces an injured post-season eligible player must have his contract selected and be placed on the club's MLB Reserve List (40-man roster) before he can be placed on the club's post-season Active Roster, and a minor league player cannot replace a post-season eligible player on the club's MLB 40-man roster if the replaced player is on the 60-day DL and the disabled player has not served at least 60 days on the DL. (A different player would have to be removed from the club's MLB 40-man roster to make room for the minor leaguer).
