Over on John Sickel's website, there is a pretty active fanpost community doing a community vote thing for the top minor leaguers.
It looks as if the Cardinal fan presence is a little lacking. Therefore hoping you will go to: http://www.minorleagueball.com/fanposts
...and take part in whichever is the more active voting fanpost. I say it like that due to every 24 hrs or so, new voting takes place. Thank you.
