We are using the in-game waivers with a waiver period one day longer than the sim period.

A copy of Waiver FAQ from the OOTP boards is posted here.

- What is the 25 Man Roster?

A team's major league roster is limited to 25 players from opening day to September 1st of that season. On September 1st, the major league roster is expanded to 40 players. A player cannot play in the major leagues without being on the 25 man roster.

- What is the 40 Man Roster?

A major league team's 40 man roster consists of an "expanded" major league roster. This allows for teams to sign additional backup players for their 25 man roster and have some sort of roster flexibility over the course of a season.

- Must a player on the 25 Man Roster be on the 40 Man Roster?

Yes. Any player on the 25 man roster must be on the 40 man roster as well. However, a player on the 40 man roster does not have to be on the 25 man roster.

- When must a player be placed on the 40 man roster?

A team must place a player on the 40 man roster if he is signed to a major league contract by the club. That player does not have to be on the 25 man roster, but must be placed on the 40 man roster. In addition, any player that the team wishes to place on the 25 man roster must be placed on the 40 man roster. Players acquired via trade or waivers who were previously on the 40 man roster with their previous team must also be placed on the acquiring team's 40 man roster.

- How can a player be removed from the 40 man roster?

A team wishing to remove a player from the 40 man roster places the player on waivers first. If the player clears waivers (no claims are made), the team then outrights the player to the minors. A team can only do this once to a player without the player having a choice. If the team does this an additional time, he can refuse assignment and elect to become a free agent. If a player has 5 years of service time, he can also elect to refuse assignment and become a free agent.

- What happens to a player's contract/salary when they are sent to the minors/out righted?

When a team signs a player to a major league deal, he is placed on the 40 man roster. If he then is out righted or otherwise demoted, his contract remains intact unless he elects to become a free agent. If the player elects to become a free agent, if his contract is guaranteed (which MLB contracts are), he will receive the remainder of his contract.

- What about player options? Where do they come into play?

A player who is signed to a minor league contract who later gets placed on the 40 man roster (but not the 25 man roster) is considered to be on "optional assignment". While on the 40 man roster, he can be called up and sent down form the majors and minors for three seasons. These are the player's three option years. These years start immediately once the player is placed on the 40 man roster. After these three seasons have passed, a team needs to place the player on waivers before he can be sent down to the minor leagues. This player is then "out of options".  An option year is burned if a player is called up during spring training and sent back to the minors before opening day.

- Who can claim a player on waivers? What team is responsible for their salary?

Probably best explained by sporr here: LINK

- What's the difference between the 15 day disabled list and the 60 day disabled list (outside of 45 days?)

Players on the 15 day disabled list are still on the 40 man roster. They are removed from the 25 man roster when they're put on the DL, but they retain their spot on the 60 day DL. A player placed on the 60 day DL is still on the 40 man roster as well, however he does not count toward the 40-man limit.  This means players on the 60-day DL still accrue service time. This does not affect a Rule 5 draftee's status with the team. When a player is activated off the 60 man DL, they must be placed back in the same roster status that they were on when they were originally placed on the DL (i.e. on the 25 man roster in most cases). Players can be moved from the 15 day DL to the 60 day DL without resetting the time already spent on the DL (i.e. a player who was originally on the 15 day DL has not played for 30 days. If he is moved to the 60 day DL, he can be activated in 30 days). A player cannot be moved from the 60 day DL to the 15 day DL. Retroactive assignments to the DL are also available for up to 10 days after the player last played. This allows a team to place a player on the DL retroactively a few days previous so that they can be activated more quickly. A retroactive assignment can go back as far as ten days previous, as long as the player did not play at all during that time.

- When is a player designated for assignment?

A player is designated for assignment; he's removed from the 40 man roster for a small period of time while the club figures out what to do with him. A team designating a player for assignment has 10 days to either trade him to another team, outright him to the minors, or release him. The team has 10 days to make the decision, meaning that a player whom the team wants to outright can wait 10 days to make the decision, then place him on waivers. A player who has been designated for assignment cannot be returned to the 40 man roster (or "undo" the designation) unless he can prove that he was injured, and the player can then be put on the DL. Basically, a player designated for assignment is in limbo for 10 days while the club figures out what to do with him.

- What is Designated For Assignment? What's good about it?

"Designated For Assignment" (DFA) is a new feature introduced in OOTP 6.10. It has two major benefits:

(1) It allows managers to make roster changes immediately while waiting to secure waivers. Previously, a manager would have to wait for a player to clear waivers before removing him from a roster.

(2) It ensures that acquired players (via waivers, trade or free agency) do not end up in the minors when they would normally not accept such an assignment. Previously, all acquired players were placed on the AAA roster, even if they had no options remaining or would have rejected a minor league assignment.

- How does a player get into the DFA area?

Mostly in one of three ways:

(1) If you attempt to demote (move from majors to minors) a player who has no option years remaining and has not previously cleared waivers, he will be placed in DFA (and on irrevocable waivers).

(2) If you attempt to remove a player from the 40-man roster who has not previously cleared waivers, he will be placed in DFA (and on revocable waivers).

(3) All newly acquired players are placed in DFA.

- Once a player is in DFA, what can I do with him?

(1) You can assign him to your major league roster (active roster).
--- You must put the player on the 40-man roster before you assign him to the majors.

(2) You can assign him to a minor league roster.
--- Players with five or more years of MLB service can refuse assignment to the minors.
--- If the player is on a major league contract, he must be placed on the 40-man roster before being assigned to the minors.
--- If the player has no option years remaining, he must clear irrevocable waivers before being assigned to the minors.

(3) You can attempt to negotiate a trade involving the player.

(4) You can release the player.

- How can I tell if my player will be a Free Agent at seasons end?

There are 172 days in a major league season.  If a player has 5 years and is on the active roster all season he will be a free agent.  If a player has 5 years and 18 days of service and there are already 46 days of service this year he won’t be a free agent. 

Waiver Trades

-Post-deadline trades are allowed, but the player must clear waivers. If a player is claimed, the teams have 48 hours to work out a deal or the claim is revoked. Any player not on the roster by September 1st will not be available for the playoffs.

Any violations (roster, trade, rules) will be punished as follows:
1st offense = Warning
2nd offense = Fine ($500,000)
3rd offense = Fine ($1,000,000)
4th offense = Fine ($1,000,000) + Loss of draft pick.

Failure to remove a player from the DFA box:
1st offense = Warning
2nd offense = Fine ($1,000,000/player)

Accumulation of excessive fines will result in termination of ownership (Commissioner's discretion).
