The Mets have set their 60-player pool for the shortened 2020 season. All teams were required to submit the names for those pools—which were implemented as part of the league’s attempt to play a shortened season amid the coronavirus pandemic—to Major League Baseball by 4:00 PM EDT this afternoon.
If the season actually gets underway, teams will have 30-man active rosters to start the season, and those rosters will gradually drop to 28- and then 26-man rosters, the latter of which was originally intended to be the case in a normal 2020 season. With no minor league season in the works this year, the remaining players within the 60-player pool are intended to serve as depth for the major league rosters as players inevitably get injured—and presumably contract COVID-19 as the league goes about conducting its season.
