Major League Baseball and the Players Association have reached an agreement on how to move forward with the complicated logistics associated with a shortened, and potentially canceled, 2020 season. The agreement will be finalized at Noon EST on Friday, at which point all roster moves will be frozen until a later date is agreed upon by both sides.
This explains why the Angels have made a scurry of moves over the past week, adding Ryan Buchter to the 40-man-roster, days before optioning him to the minors, along with three other players. The team was trying to handle as much business as possible before they are stuck with their current iteration of the 40-man roster and minor league assignments for the foreseeable future.
