Sickles Drops The Hammer

John Sickles, minor league guru, gives the Nationals' prospects their letter grades.

He likes Mike Hinckley, a lot.

Hinckley is often ignored when top pitching prospects are discussed, but I rank him fourth among minor league lefty prospects, behind only Kazmir, Francis, and Meyer. Hinckley is a textbook case of how a "projectable" high school southpaw is supposed to develop.

Check it out for the top-2o prospects. Sickles has a better handle on the minor leagues than any one. If you have any questions, post it on his board, he seems to be really good about answering questions.
