Seattle Mariners Top 20 Prospects for 2008

All grades are EXTREMELY PRELIMINARY and subject to change.

1. Adam Jones, OF, Grade B+
   
2. Jeff Clement, C, Grade B+
   
3. Carlos Triunfel, SS, Grade B+
   
4. Chris Tillman, RHP, Grade B+
   
5. Wladimir Balentien, OF, Grade B+ (maybe Grade B?)
   
6. Tony Butler, LHP, Grade B-
   
7. Phillippe Aumont, RHP, Grade B-
   
8. Juan Ramirez, RHP, Grade C+
   
9. Greg Halman, OF, Grade C+ (tremendous tools, but huge strikeout problems)
   
10. Nick Hill, LHP, Grade C+
    
11. Adam Moore, C, Grade C+  (interesting sleeper prospect)
    
12. Kuo Hui Lo, OF, Grade C+ (sleeper I like a lot)
    
13. Matt Mangini, 3B, Grade C+
    
14. Carlos Peguero, OF, Grade C+ (great power, but strikeouts galore!)
    
15. Michael Saunders, OF, Grade C+
    
16. Robert Rohrbaugh, LHP, Grade C+
    
17. Young Chi Chen, 2B, Grade C+
    
18. Austin Bibens Dirkx, RHP, Grade C
    
19. Ryan Rowland-Smith, LHP, Grade C (good LOOGY)
    
20. Mark Tuiasosopo, 3B, Grade C

Other Grade Cs, who are interchangeable with those above, include Nate Adcock, Denny Almonte, Aaron Brown, Danny Carroll, Casey Craig, Brodie Downs, Joe Dunigan, Nolan Gallagher, Alex Liddi, Mario Martinez, Kam "The Almighty" Mickolio, Ricky Orta, Edward Paredes, Kyle Parker, Anthony Varvaro, and Jake Wild.

Again, don't get bent out of shape about the exact placement of the C+ guys.

The top four B+ guys also can vary. If you are looking for long-term upside, Triunfel is the best but his risk is also high. Jones and Clement are much closer to the majors, less risky, and should be impact guys themselves, so it depends on what you want to emphasize. I like what Tillman did last year in the Cal League.

Of course, full statistics and reports on over 1,000 other players will be in the 2008 Baseball Prospect Book, now available for pre-order. Ships the first Monday in February!
