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.

  • Oh, I'm sure you're right. He's not 27-27 in saves for nothing. But, man, I hope they learned last night that he didn't throw a single pitch in the zone to KB, Contreras or Baez, and they all just kept swinging.

  • Sounds like a much better game than last night's fiasco in Flushing.

  • I'm pretty sure it looks like a sweet pitch on the way in. How many sinkers like that are there at 98 mph? I agree that they should just do a Lackey and stand their with their bat on their shoulders until he throws a strike next time, but I can see how that's hard to do.

    The bullpen, on the other hand, is a mess, and Heyward is starting to piss me off.

  • I noticed that too. He's getting to everything, but when he gets right under it on a high flyball he looks uncomfortable

  • Wow, did they blow this game. Stupid plays by the kids in the 7th -- Almora throwing to 3rd instead of 2nd to keep the DP in order (when a DP probably wins the game) and Baez throwing to 3rd (to a backpedalling KB) instead of getting the easy 2nd out at first - cost them the game. Also, Contreras almost throws the ball into RF on a nonexistent pick-off play. And Maddon, for using Peralta in the first place. Did they do a bunch of shots in the dugout before the 7th? Unbelievably bad baseball. I thought Almora had a high baseball IQ?

  • Yep, can't say I disagree with that. His first batter and resulting walk was just brutal. Reminded me of a bit of Jacque Jones spiking his throws into the ground from RF.

  • The use of Peralta in any semblance of a high leverage situation is questionable at best.

    fixed that for ya.

  • The use of Peralta in any semblance of a high leverage situation is questionable at best. Hind sight is easy but Peralta had nothing.

  • Why is Almora jumping up on catches?

  • "Tommy La Stella (hamstring) will remain on his minor league rehab assignment through at least Friday."

    should be an interesting roster shuffle once these guys trickle back in. i imagine patton or peralta are on the hot seat for la stella's return.
