The Cardinals are already in a 40-man roster crunch, so I don't expect any other players to be added before the end of the year. The organization's September additions are likely to be mostly from the disabled list. Players like Aledmys Diaz, Brayan Pena, Trevor Rosenthal and Matt Adams hope to be back next month. Matt Holliday, Michael Wacha, Jordan Walden and Lance Lynn could rehab quickly enough to be options as well. As far as Minor League callups are concerned, they could well be limited to relievers like Miguel Socolovich and Dean Kiekhefer.
