Nationals farm system preliminary grade breakdown

I am working on the Washington Nationals prospect list, which I have distilled down to 33 names. Here is the current grade breakdown. Look for the final list with comments tomorrow.

One Grade A-
One Grade B
Seven Grade B-
Nine Grade C+
15 Grade C

The A- is obviously Lucas Giolito. You can speculate about the others which is why this thread is here, of course. There are some very intriguing players in this system including many in the C+/C category.
