In their latest update, Baseball America has Max Clark at number 15 overall, Colt Keith at 26. Langford at 13, Crews at 4. I think just yesterday they had Clark at 19, so he's moving up the list quickly. Walker Jenkins is at 16.
Edit: Oops, that was MLB.com's ranking. Baseball America has Keith at 19, Clark at 21.
