MLB Minor League Assignments and Option Rules
Managing a professional baseball roster requires a delicate balance between developing young talent and maintaining a competitive Major League squad. Central to this process is the system of optional assignments, governed by MLB Rule 11 (C). This system dictates how players move between the major and minor leagues, ensuring that players are not indefinitely stalled in the minors while giving teams flexibility in roster management.
Key Facts
- Players typically have three option years once placed on the 40-man reserve list.
- As of 2022, a player can be optioned to the minors a maximum of five times per season.
- A player is considered to have used an option year if they spend at least 20 days in the minors during a season.
- Players with five years of major-league service can block a minor league assignment via veterans' consent.
- Designated for Assignment (DFA) removes a player from the 40-man roster immediately, giving the team seven days to trade, release, or waive them.
The Option System
When a player is added to a team's 40-man reserve list but is not on the active major league roster, they are on optional assignment. This allows the organization to move the player between the major and minor leagues without exposing them to other teams.
Option Years and Thresholds
Standardly, a team has three option years for any player on the 40-man list. An option year is consumed if the player spends 20 or more days in the minor leagues during that season. These options do not reset if a player is traded; the count continues from when they were first placed on a 40-man roster.
In specific cases, a team may acquire a fourth option year for players with less than five full seasons of professional experience. This occurs if the player meets one of two conditions:
- They spent fewer than 90 days on an active professional roster in a season (common for those in rookie or Class A short-season leagues).
- They spent fewer than 60 days on an active roster, followed by fewer than 30 days on the injured list.
Seasonal Limits and Recall Periods
Under the current collective bargaining agreement effective from 2022, players are limited to five options per season. Once optioned, there are mandatory waiting periods before a player can be recalled to the majors: 10 days for position players and 15 days for pitchers or two-way players. Exceptions include recalls to serve as the "27th man" for doubleheaders or replacing a player placed on the injured list.
Once all option years are exhausted, a player is "out of options." To send such a player to the minors, the team must place them on waivers and have them clear (meaning no other team claims them), or obtain veterans' consent.

Designated for Assignment (DFA)
When a team needs to clear a spot on the 40-man reserve list immediately, they may Designate a player for Assignment (DFA). This action removes the player from the roster instantly, providing the team a seven-day window to determine the player's future.
During these seven days, the team has three primary options:
- Trade the player to another organization.
- Release the player entirely.
- Place the player on waivers. If the player clears waivers, they can be "outrighted" to the minors.
A player who is outrighted is removed from the 40-man list but continues to be paid according to their guaranteed contract. Notably, a player can only be outrighted once in their career without their explicit consent.
Veterans' Consent
To protect experienced players, MLB implements the veterans' consent rule. Any player with five years of major-league service cannot be assigned to a minor-league team without their permission, regardless of their remaining options or waiver status.
If a veteran withholds consent, the team must either keep them on the major league roster or release them. In both scenarios, the team must honor the contract's payment terms. If the player is released and signs a less lucrative deal with a new team, the original team is responsible for paying the difference in salary.

Frequently Asked Questions
What happens when a player is "out of options"?
When a player has used all their option years, they can no longer be moved freely to the minors. The team must place them on waivers; if another team claims them, they leave the organization. If they clear waivers, they can be sent down, subject to veterans' consent rules.
Does a trade reset a player's option clock?
No. Options do not reset upon a trade. The player retains the original three option years that began when they were first added to a 40-man reserve list.
How does a rehabilitation assignment affect option time?
Time spent in the minor leagues while on a rehabilitation assignment for a player already on the major-league injured list does not count as time spent in the minors for option purposes.
What is the difference between being optioned and being outrighted?
An optioned player remains on the 40-man roster and can be recalled. An outrighted player is removed from the 40-man roster entirely, though they still receive their guaranteed salary.
Can a veteran player be forced into the minors?
No. A player with five years of major-league service must give their consent to be assigned to a minor-league team. If they refuse, the team must either keep them on the active roster or release them.
