Seattle Mariners preliminary prospect grade breakdown

Here's the first run grade distribution breakdown for 51 Seattle Mariners prospects, listed below.

Grade A: Zero
Grade A-: Zero
Grade B+: Two
Grade B:  Zero
Grade B-: Nine
Grade C+: 15
Grade C:  25

I expect the final breakdown will be very close to that, although there are a lot of C+/C borderline grades to plow through.
