Baltimore Orioles preliminary prospect grade breakdown

I am working on the Baltimore Orioles Top 20 prospects list for 2018. My first pass through the system gave the following results:

Grade A: Zero
Grade A-: Zero
Grade B+: One
Grade B: Two
Grade B-: Five
Grade C+: 18
Grade C: 40

There’s some play there along the borders between grades (notably C+/B- boundary and C/C+ boundary) but the final results should be close to this.
