Revisiting the top 30 prospects of 2005 (via Baseball America)

1. Joe Mauer, c, Twins 

2009 AL MVP has progressed and succeeded just as everyone foresaw.
2. Felix Hernandez, rhp, Mariners

King Felix showed flashes of potential until unleashing his talent with a strong '09
3. Delmon Young, of, Devil Rays

after being traded to Minnesota, Young has found a niche in the Twin's system.
4. Ian Stewart, 3b, Rockies

versatile infielder who hits for above-average power in homer-heaven Colorado
5. Joel Guzman, ss, Dodgers 

never caught on as Furcal's successor and is struggling to stick with a team
6. Casey Kotchman, 1b, Angels

top-tier fielder, good contact hitter has relocated several times in the last couple years
7. Scott Kazmir, lhp, Devil Rays

has streaks where he is unhittable, then goes through slumps. Talent is undeniable.
8. Rickie Weeks, 2b, Brewers

Mike Cameron-type power, Ryan Howard-like strikeout numbers 
9. Andy Marte, 3b, Braves

finally found a spot as a utility player in Cleveland 
10. Hanley Ramirez, ss, Red Sox

best shortstop in the Majors, only reason people attend Marlins games
11. Lastings Milledge, of, Mets

egotistical big-shot that couldn't make it in New York, and is just getting by in D.C.
12. Dallas McPherson, 3b, Angels

reduced to the role of pinch-hitter, will most likely never be a starter
13. Matt Cain, rhp, Giants

most underrated pitcher in the majors, success overshadowed by Lincecum
14. Jeff Francoeur, of, Braves

Rickie Weeks outfield edition
15. Prince Fielder, 1b, Brewers

often overlooked, but in contention with Ryan Howard for best power in AL. 
16. Adam Miller, rhp, Indians

hasn't thrown a pitch in the majors, probably never will
17. Jason Kubel, of, Twins

breakout '09 where he hit .300, 28 homers, and 103 RBI as the Twins DH.
18. Jeremy Hermida, of, Marlins

not very accomplished, traded to the Bosox this offseason.
19. Chad Billingsley, rhp, Dodgers

arguably the ace of a very good rotation in Los Angeles
20. Jeff Niemann, rhp, Devil Rays

good '09 season with 13 wins and a sub 4 ERA
21. Brian Dopirak, 1b, Cubs

WHO?????????
22. Carlos Quentin, of, Diamondbacks

Great '08 season with 30+ homers, 100+ RBI, but struggled with injuries in '09
23. Jeff Francis, lhp, Rockies

has had a mix of good and bad times as the most consistent pitcher in Colorado

24. Nick Swisher, of, Athletics

situational player who was one of the original "Moneyball" draft picks

25. Jose Capellan, rhp, Brewers

100 mph heat hasn't brought Cappelan to superstardom

26. Chris Nelson, ss, Rockies

still considered a top prospect for the Rockies (only 24 years old)

27. Ryan Howard, 1b, Phillies

one of the most feared hitters in Majors; 40 homers in every season but his rookie year
28. J.J. Hardy, ss, Brewers

broke out in 2008, fluctuated between majors and minors in 2009
29. Mike Hinckley, lhp, Nationals 

nothing more than a middle reliever here.

30. Edwin Jackson, rhp, Dodgers

couldn't succeed in Los Angeles, but flourished in Tampa and Detroit.
