23. Nolan Arenado, 3B, Colorado Rockies (age 21)
Current level: Double-A (Tulsa)
Preseason ranking: 26
Now that the preseason hysteria that had some folks calling for Arenado to get the starting third-base job in Denver has died down, he looks more like the prospect he always was: a high-contact hitter who should hit 20-25 homers at sea level with adequate defense at third.
Playing in Double-A for the first time in his career, the 21-year-old Arenado has hit an impressive .303/.352/.436 slash with 3 home runs.
