On further thinking, I'm dropping Adrian Ortiz to Grade C and revising the Top 20 to look like this:

16. Jarod Plummer, RHP, Grade C+  (sort of the Brazell of pitchers)
    
17. Mitch Maier, OF, Grade C  (Looks too low. Might move up to C+)
    
18. Joe Dickerson, OF, Grade C
    
19. Matt Mitchell, RHP, Grade C
    
20. Derrick Robinson, OF, Grade C
    
21. Adrian Ortiz, OF, Grade C
