What is a Minor League Option? Definition and Examples
A minor league option lets a team freely send a player on the 40-man roster to the minors during a season; each player gets three option years, with a possible fourth under the 2022 CBA.
What is a Minor League Option?
A minor league option is the mechanism by which an MLB team can send a player on its 40-man roster down to a minor league affiliate without first exposing him to waivers. Once a player is added to the 40-man, he is "optionable" only if he has remaining options. Each player is granted three option years, and under the 2022 collective bargaining agreement, a fourth option is available if the player has accrued fewer than five full professional seasons after exhausting his first three. An "option year" is a season — not a single demotion — meaning a player can be shuttled between MLB and AAA dozens of times within one season and only burn one option. Once a player is out of options, the team must either keep him on the 26-man active roster, place him on the injured list, DFA him, or pass him through outright waivers to send him down.
How Options Are Tracked
The option clock starts the first season a player is on the 40-man roster and is sent to the minors for at least 20 days. Brief 20-day-or-fewer demotions do not consume an option year. Service-time considerations are tracked separately — being optioned does not stop the player from accruing service time up to a cap (you can earn up to a maximum based on actual MLB days, even while optioned out, but only when officially active up top).
Key rules:
- Three option years standard, plus possible fourth (post-2022 CBA)
- An option is "used" the first time a player is optioned in a given season for more than 20 days
- A player on the 40-man but never sent down does not burn an option
- Veterans with five years of MLB service have the right to refuse an outright assignment
Worked Example
Consider a pitcher like Triston McKenzie of the Cleveland Guardians. He was added to the 40-man roster in 2020, when he made his MLB debut. He bounced between AAA Columbus and Cleveland in 2021 and 2022, each year burning one option. By 2023, he had used all three. When he struggled with command and injuries in 2024, the Guardians could not simply send him to AAA — they had to DFA him to clear his roster spot, exposing him to waivers and a potential claim by another team.
Contrast that with a player like Drew Thorpe, drafted in 2022 and added to the 40-man in late 2023. As of 2025, he has used only one option and remains fully flexible — the White Sox can shuttle him to AAA freely through 2026 and 2027 before facing the same out-of-options cliff.
Why Options Matter
Options are one of the most impactful roster-construction tools in baseball. Trade-deadline buyers heavily weight remaining options when valuing prospects and bullpen depth: a reliever with two options remaining is significantly more valuable than an equally talented reliever with zero, because the team can stash him at AAA when fresh arms are needed. Out-of-options players frequently become April waiver claims, spring training cuts, or post-deadline DFA casualties because teams cannot keep them in their development pipeline without losing them.
Fantasy and dynasty managers track options too — a prospect with all three options intact has a longer leash for slow MLB starts, while an out-of-options swingman is one bad week away from being released.
Limitations and Misconceptions
Options are not the same as service time — a player can have all three options remaining while already accumulating MLB service, and vice versa. Options also don't apply to players not on the 40-man roster; a player drafted but unprotected can move freely through the minors until added. The fourth-option rule introduced in 2022 is also often misunderstood: it isn't automatic, and it requires fewer than five full pro seasons completed when the third option is exhausted.
