For those unfamiliar with mr. Sickels, he doesn't rank on a 1, 2, 3 scale, but rather A+, A, A-, B+ B etc etc on down the line, and will post what he feels are the top 20 in the Jays Org.
Notably absent from his preliminary list of 35 there is Urena, but I think the crowd will win him over and get him in there somewhere.
