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.

  • "The Boston Red Sox were banned from signing any international players for the next year and had five of their teenage prospects declared free agents on Friday after a Major League Baseball investigation showed they circumvented signing-bonus rules last year, a source familiar with the situation told Yahoo Sports."

  • The thing with Heyward is its not just free agency. He is way under performing his career #s. He's making the same % of contact but his soft contact is much higher and hard contact much lower than all his previous years so there is something very specifically going on this year causing the issues. Chances are he will eventually get back to his previous #s and it's better to get the slump now and get that hot run later but I wish I knew what is different about this year. He's either just not seeing the ball as well or a swing change is causing it.

  • Only 3 pitches for Leathersich. Not much of a rehab outing.

    Thanks for the reporting Phil.

  • He's the nastiest pitcher I've seen in awhile. I'm gonna give them all a mulligan on this one.

    Coghlan's strike out was more disappointing. He was fighting off a lot of pitches and not swinging at crap, and on the last pitch, he swung at stuff he was laying off, and struck out.

    And Heyward, too. I don't blame Heyward - I blame free agency. I hate it. You almost never get a valid return on the investment.

    I look forward to the day when ball players own the teams. The current economics are not sustainable.

  • 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.
