Once again, if you have a serious interest in the minor leagues, bookmark Baseball America on your browser; and if you have some cash to spare, consider getting an online subscription too. There's lots of good stuff in there, especially around Draft Day in June.
At the moment, subscribers are getting BA's Top 20 prospects in each minor league. Naturally I won't be reproducing the analyses, but I can tell you that in the International League, Kevin Cash, Gabe Gross and Jason Arnold rank 15th, 16th and 20th; BA says they need to improve their hitting, power and command, respectively, to become impact players in the majors. In the Eastern League, Alexis Rios ranked 2nd, followed by Gil Quiroz (4th), Dustin McGowan (5th) and David Bush (a somewhat suprising 19th). BA simply raves about McGowan, saying that he needs only better command of his pitches to become a bona fide ace. 2005-07 could be a lot of fun in Toronto.
