Paddack will probably be activated today and a move will have to be made for him. Same for Stewart, So two moves off the 40-man today. Gordon's 20-day rehab will be over on October 5, Alcalá's on October 8, so if the Twins are still playing then, two additional subtractions would have to be made to make room for them.
In a previous thread someone predicted that Jovani Moran would be recalled and placed on the 60-day IL to make a space. If the Twins can do that, I'm sure they will. Otherwise, it is veterans like Keuchel, Floro, Gallo or Luplow or fringe roster guys like Celestino, Sands and Winder.
