60-day Injured List
The 60-day injured list (known as the 60-day disabled list until the end of the 2018 season) is the longest of the Major League Baseball injured lists. Players placed on the 60-day injured must remain on it for a minimum of 60 days and are temporarily removed from a club's 40-man roster, which often makes the list a last resort for clubs.
If a club doesn't need a 40-man roster spot to replace an injured player, the player may be kept on the 10-day injured list longer than 60 days rather than being transferred to the 60-day injured list. That way, the club won't need to risk losing another player by going through the process to clear a spot on the 40-man roster when the injured player is ready to return.
After the 2018 season, the 7-day disabled list (or "DL"), 10-day disabled list and 60-day disabled list were renamed, becoming the 7-day injured list, the 10-day injured list and the 60-day injured list.
The decision to change the 15-day injured list to the 10-day injured list prior to the 2017 season did not affect the parameters of the 7-day injured list or the 60-day injured list.
MLB was set to bring back the 15-day injured list specifically for pitchers and two-way players (position players who are eligible to pitch in any circumstance) while instituting new restrictions on position players pitching for the 2020 season, but the rules were changed amid the COVID-19 pandemic.
Rather than a 10-day injured list for position players and 15-day injured list for pitchers and two-way players, the 10-day injured list remained in place for all players in the shortened season, and there were no restrictions on position players pitching. There was also a separate COVID-19 injured list that had no minimum duration, and the 60-day injured list was reduced to 45 days.
