According to mlbtraderumors.com, the Cardinals have let other teams know Brendan Ryan is available. As mlbtraderumors mentions, starting shortstops can be hard to come by, but there doesn't really seem to be a huge market for them other than the Os, Buccos and Padres.
So we now have JJ Hardy, Jason Bartlet and Ryan available. This can only be a good thing for the Buccos. It there is a short demand and teams are looking to move players for either the roster spot or salary relief, then the Buccos may not have to give up a lot to get one.
Of the three available, which one would you prefer?
