MLB Roster Limits

Each MLB club is permitted to reserve no more than 40 players on its MLB Reserve List, which is why the MLB Reserve List is also called the "40-man roster."

Each MLB club is permitted to roster a maximum of 25 players on its MLB Active List (also known as the "25-man roster") beginning at 3:00 PM (Eastern) on MLB Opening Day up through 11:59 PM (Eastern) on August 31st, and then the Active List roster limit is increased to a maximum of 40 players beginning on September 1st and extending through the last game of the MLB regular season. The Active List maximum roster limit reverts back to 25 players again for post-season play (LDS, LCS, and World Series). If MLB regular season games are scheduled prior to MLB Opening Day (for example, if MLB games are played in Japan, Mexico, Australia, etc), the MLB Commissioner will determine the Active List maximum roster limit for those games.   

Each MLB club is required to roster a minimum of 24 players on its MLB Active List during the MLB regular season (and post-season), but in the event of an unusual or unavoidable circumstance (such as a multi-player trade or multiple trades made at about the same time where several players have been acquired but have not yet arrived), a club's MLB Active List can temporarily go below 24 players, but for no more than 48 hours. (Even though an MLB club could play with a 24-man MLB Active Roster for an entire season (and save about $500K in payroll by doing so), in practice and by convention no MLB club would do that unless all clubs did).

No more than 16 players on a club's MLB Reserve List (40-man roster) may be on Optional Assignment at any one time.

A club can recall a player from a minor league Optional Assignment and place the player on its "Taxi Squad" for one day. If the player is not added to his club's MLB Active List by 3 PM (Eastern) the next day or at least three hours prior to the scheduled start of the next day's game (whichever is later), the player must be removed from the Taxi Squad and returned to his minor league assignment. A player on the Taxi Squad does not count against his club's MLB Active List, and the player does not accrue MLB Service Time while on the Taxi Squad. The most common reason to recall a player and place him on the Taxi Squad is when a club is considering whether to place a player on the Disabled List but has not yet decided.

Beginning on MLB Opening Day up through August 31st, a club can temporarily add a 26th player to its MLB Active List on any day where two games are scheduled, as long as the second game was scheduled at least 48 hours in advance. If the second game was scheduled less than 48 hours in advance, a 26th man can be temporarily added to a club's MLB Active List for the second game only.

1. The "26th man" must be on the club's MLB Reserve List (40-man roster) or has to be added to the club's 40-man roster that day.

2. The "26th man" does not have to be a pitcher.

3. In the case of a second game being scheduled at least 48 hours in advance, the 26-man Active List limit is in effect for both games, but the "26th man" cannot be switched between games.

4. A minor league player can be added to a club's Active List as the "26th man" even if he has not spent ten days on Optional Assignment (or Outright Assignment) prior to being added.

5. A "26th man" can remain on the Active List and a different player can be dropped the next day, as long as the "26th man" was not called up from the minors prior to spending at least ten days on Optional or Outright Assignment. However, a player called up as the "26th man" prior to spending at least ten days on Optional or Outright Assignment could remain on the 25-man roster if the player replaces a player who is placed on the Disabled List (or other MLB inactive list) the next day.

6. If a player is recalled as the "26th man" and is optioned or outrighted back to the minors the next day, the "10-day rule" clock (prohibiting a player from being recalled until he has spent at least ten days on Optional or Outright Assignment, unless he is replacing a player who is placed on the DL or other MLB inactive list) does not start over again. However many days toward ten that the player spent on Optional or Outright Assignment prior to being recalled as the "26th man" counts toward the ten days.

7. The "26th man" accrues one day of MLB Service Time.

  • I definitely hang around here looking to reply to your comments as noticed by my nearly year long absence.

    there's a fine line between posting something relevant, useful or at least humorous versus posting something irrelevant, useless or unfunny...actually it's rather quite a thick line and easy to see for most people not named crunch.

  • I certainly am digging the RISP machine Zobrist version.

  • Cubs are taking advantage of bad D by their opponents -- did it a few times in PIT and the Nats botched 2-out rundown leads to 3 Cub runs in the 8th. Which were nice to have.

    I hope Kyle had fun at the dance party -- he was terrific.

  • i hope he's getting more consideration for the 2-slot vs lefties, too.

  • I hope we can dispense with the Zobrist RISP concerns.

  • Is this heaven?

  • They call me Schwarberino because I'm basically Ruth,
    and as long as we're rapping I'm gonna tell you the truth:
    This team would be even better if I wasn't laid up;
    we'd win the World Series, the Superbowl, and the Stanley Cup.
    As long as we're at it, I'm putting the Premier League on notice.
    Hell, if I were healthy, Epstein could run for POTUS.
    My busted knee's even sadder than this presidential kerfuffle,
    but my first rehab assignment will be the World Series Shuffle.

    I am avoiding grading papers.

  • Phil,

    With Mutton on the DL now, does Victorino finally get to Iowa?

  • Chat ... is happening.

  • I agree completely with Dusty. I appreciate him much more as the Nats skipper than as the Cubs.

  • so, what you're saying is you keep bringing up something over and over and over and over and over and over and over and over and over and over and over and over and over like you did with this issue for years back in the day...and obviously still into today...

    ...but that's fine if you do it.

    brb, forming my next dozen replies for why you should shut up and never say anything about it again...oh wait, no i'm not because i'm not hanging around looking to tell you to shut up about repeating the same thing over and over and over and over...

  • Heyward looked fine shagging flies in BP. Wouldn't surprise me to see him in the line up tomorrow.

  • this seems like it could be an interesting series...parachat worthy.

  • speed leads...nothing ever changes. that's been a dusty thing since...forever.

    holy shit, really? I made the comment because I had just discovered this novel trait that Dusty possesses.

    btw, check out the leadoff hitter of the WS champion KC last year.

    waaaat????? again with the knowledge dropping, I literally had no idea.

  • speed leads...nothing ever changes. that's been a dusty thing since...forever.

    worst part is he's barely a speedster...just the best fitting.

  • Gotta make sure you're not clogging up those bases.
