According to BA:

Of course, I;ve been bitching for awahile that AAA semi-stars that project as MLB regulars should be given more weight than they are getting in out internal rankings here, and this helps my feelings - guys like Chris Perez, Jason Motte, David Freese, and Allen Craig are surely in the Cards top 10, and probably help tip the Cards system into the Top 10.  Interesting, though, that BA is traditionally the organization that tends to upgrade raw talent, whereas the guys I am talking about are the steady reliable types.

Off the top of my head, teams I see ahead of teh Cards would be:

TB

ATL

OAK

TEX

SFO

BAL?

BOS?

The link refers to STL being #8.
