Ramirez, 39, retired in April after a second violation of the league's Joint Drug Prevention and Treatment Program. The violation came with a 100-game suspension, but the 11-time All Star instead chose to hang up his cleats.
The Office of the Commissioner and the Players Association have decided that the suspension will be reduced to 50 games upon Ramirez's return. It will take effect when he signs with a team.
He previously served a 50-game suspension in 2009 as a member of the Dodgers and is currently facing charges in Florida for allegedly striking his wife with an open hand on September 12.
