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.

  • Brian Matusz, supposedly he has attachments. Hope it's not like an email with a virus attached.

  • One thing to remember about Chapman -- he can be magic, but his ERA is higher than Rondon's this year. 100+ mph is fun, but I'd love to see a few more sliders. I think he enjoys the crowd reaction from 103 mph.

  • "Diamondbacks designated RHP Josh Collmenter for assignment."

    aww...he was my 2nd favorite crapballer. his control issues are rather severe at the moment.

  • Wow -- Chapman gives up a hit and everything completely caves in. I think the Cubs went into collective shock.

    Stolen base with the pitcher holding the ball, WP that should have been caught or blocked, then Russell with a 2-out error on a routine play. Cubs handed them 2 runs. Throw in a Fowler bobble and it was a mess.

    Hopefully, that is all out of their system now -- let's get a W tomorrow.

  • First time I've ever seen a base running slump -- he's made some poor decisions recently, but I thought it was a great idea to try to score there -- it's not like Heyward was going to get a 2-out hit against a LHP. Sliding feet-first into home is probably the safe (ugh) way to go, but it's hard to get the foot on the plate.

  • Yup. He got squeezed (twice) on the first walk, but, when you have one-run lead and the other team is trying to make an out -- take the out.

  • Clearly the Cubs need to clear out the farm and trade for another closer

    Where's Ed Lynch when you need him?
