Adding Players to MLB Reserve List

Only players on an MLB Reserve List (40-man roster) can be placed on an MLB Active List (25-man roster).

A free-agent with prior MLB and/or minor league service who signs a Major League contract must be added to his club's MLB Reserve List (40-man roster) when he is added to an MLB Active List or when the contract is filed with the MLB Commissioner (whichever comes first). Contracts must be filed with the MLB Commissioner within 20 days of signing.

A club must add a player to its MLB Reserve List immediately if the player is acquired as the result of a waiver claim, or if a player on another club's 40-man roster is acquired in a trade, or if a player is selected in the Major League Phase of the Rule 5 Draft.

In addition, an MLB club generally has the option to add any player who is on the reserve list of one of its minor league affiliates to its MLB Reserve List (40-man roster) at any time. The exceptions are:

1. A minor league player eligible for selection in the Rule 5 Draft cannot be added to an MLB 40-man roster during the period of time beginning with the filing of MLB and minor league reserve lists on November 20th (or November 19th if November 20th falls on a Saturday, or November 18th if November 20th falls on a Sunday) up through the conclusion of the Rule 5 Draft.

2. A minor league player who was sent outright to the minors cannot be added back to his club's MLB 40-man roster until he has spent at least 10 days on outright assignment, unless the player is selected to be the "26th man" on a day where a doubleheader was scheduled at least 48 hours in advance, or is selected to replace a player on the 25-man roster who is placed on the Disabled List, Bereavement List, Paternity List, Restricted List, Military List, Disqualified List, or Ineligible List, or if the season (including post-season playoffs) of the minor league team to which the player is assigned is over, or if the player is traded.

3. A minor league player eligible for selection in the Rule 5 Draft who was sent outright to the minors anytime after the previous Rule 5 Draft cannot be added back to his club's MLB 40-man roster during the period of time beginning at 5 PM (Eastern) on the 5th day after the final game of the World Series up through the conclusion of the Rule 5 Draft.

4. An unsigned minor league player who is eligible to be a Rule 55 minor league free-agent (player was previously released in his career and/or player has spent all or part of at least seven separate seasons on a minor league active list or disabled list) cannot be unilaterally added (by selection) to his club's MLB 40-man roster any later than 5 PM (Eastern) on the 5th day after the final game of the World Series (or 5 PM Eastern on October 15th if the World Series is canceled).

5. A player on an MLB Reserve List (40-man roster) who is given his Outright Release during the period of time extending from September 1st through March 31st cannot be added back to the MLB 40-man roster of the club that released the player until May 15th, and a player on an MLB 40-man roster who is given his Outright Release during the period of time extending from April 1st through August 31st cannot be added back to the MLB Active List of the club that released the player for at least 30 days.

6. A player who has not previously signed an MLB or minor league contract can be "Signed for Future Service" (contract is for the following season) if the player signs a Major League contract after July 1st. A player who is "Signed for Future Service" by an MLB club must be placed on the club's MLB Reserve List (40-man roster), and cannot play in MLB or in the minor leagues until Opening Day of the following season. (Attendance at a post-season Instructional League and/or participation in Instructional League games do not count). A player on an MLB 40-man roster who is "Signed for Future Service" cannot be sent to the minors by Optional or Outright Assignment any earlier than 20 days prior to MLB Opening Day (same as a Draft-Excluded Player).

7. Beginning in 2012, players signed after being selected in the MLB Rule 4 Draft, players signed as Non-Drafted Free-Agents (NDFA) after being eligible for selection in the MLB Rule 4 Draft, and international players subject to the International Signing Bonus Pool rule, cannot be signed to a Major League contract.

  • welcome to the cubs j.nathan.

    2 pitches into the inning and there's a guy on 3rd with 0 outs (triple).

    his velocity is hanging around 91/92mph.

  • a.russell out and down into the clubhouse...no one knows why.

    it's very hot on the field, so it might be heat related.

  • Miller park roof is closing. Hmmm, might play differently now?

    Lester at 72 pitches through 3. Roof closing might get him through 6.

    Middlebrows pulls a calf or hamstring. Len says he blew a tire rounding 1st. Nieuwenhuis enters game.

    Now roof opening. Dizziness. No AC in the ballpark wrt the field.

  • just to lighten the mood:
    Shark's day: 5.2 IP 5 Runs (all earned), 8 Hits, 2 HR. Left the game down 5-0 to Yankees.

    Anyone expecting game 4 NLCS Shark vs Hammel or Lackey?

  • First inning: two on, no out, Rizz and Zobrist due up. Don't score.
    Third inning: two on, one out, KB and Rizz due up. Don't score.

    This is getting' old, fellahs.

  • 62 through 2ip...yow.

    it's an off day for d.ross, too. the wild pitch + passed ball in 2 separate strike 3 calls allowing the runner to reach 1st and the 5sb through 2ip makes for a bad game so far. ross cant shoulder any blame for some of those SBs, especially that villar steal of 3rd while lester watched him.

  • 39 pitch inning by Lester. I guess it's a wash vs yesterday's 1st when Lackey gave up 2 run HR.
