The Temporarily Inactive List is for minor league players only.
It is essentially an in-season excused Leave of Absence, and it is used for Paternity Leave, Bereavement Leave, and Family Medical Emergency Leave, as well as when a player is delayed reporting to a new club, or is attending college, or is incarcerated, or has returned home for personal reasons. Only minor league players (including players on Optional Assignment to the minors) can be placed on this list.
A player on the Development List counts against the in-season minor league 180-man Domestic Reserve List or 70-man International Reserve List (or MLB 40-man roster if the player is on Optional Assignment), but he does not count against the minor league club's Active List roster.
NOTE: If the Domestic or International Reserve List is full, a player who ordinarily would have been placed on the Temporarily Inactive List can be placed on the Restricted List instead, but placing a player on the Restricted List does require the approval of the MLB Commissioner).
A player cannot be placed on the Temporarily Inactive List any earlier than the first day of his minor league club's regular season, the player must remain on the Temporarily Inactive List for at least three days, and a player on the Temporarily Inactive List must be reinstated no later than the day after the conclusion of his club's season.
A player normally is not paid while on the Temporarily Inactive List (club option).
