New York Yankees farm system preliminary grade breakdown

I am working thru the New York Yankees prospect list. There are 38 players I am working on, with the current breakdown looking like this:

One Grade A-
One Grade B+
One Grade B
Eight Grade B-
10 Grade C+
17 Grade C

There is some play in the B-/C+ area so there could be some changes there but the final totals should be similar to that.
