A club may place an injured player on the 15- or 60-day disabled list by submitting to the commissioner’s office an application, accompanied by a diagnosis from the club physician. A player on either list continues to accumulate Major League service time, but he must remain inactive for a minimum of 15 or 60 days, with Day 1 beginning after the player’s last game appearance. A club may make the placement of a player on either list retroactive to the last date on which he played, up to a maximum backdating of 10 days. A club may send a player on the DL to the minor leagues for a rehab assignment lasting a maximum of 20 days for position players and 30 days for pitchers.

15-Day Disabled List

• A player on the 15-day disabled list does not count against the 25-man active roster but continues to count against the 40-man roster. There is no limit to the number of players a club may put on the 15-day disabled list. A player may be activated beginning Day 16, though the club is not required to reinstate him at any specific time.
• A player may be transferred from the 15-day list to the 60-day list, but the opposite is not permitted. If a player is transferred, his time on the 15-day list is credited toward the minimum stay on the 60-day list.

• A player on the 60-day disabled list does not count against either the 25-man or 40-man roster. A player may be activated beginning Day 61, though the club is not required to reinstate him at any specific time. A player placed on the 60-day list after August 1 remains there for the rest of the season.
• There is no limit to the number of players a club may put on the 60-day list, but a player may not be placed on (or transferred to) the 60-day list unless the club’s 40-man roster is full. Once the season ends, a player on the 60-day disabled list must be reinstated to the 40-man roster or designated for assignment.
