11. Miguel Sano, 3B, Minnesota Twins (age 19) Current level: Low Class A (Beloit) Preseason ranking: 28 He's cooled off since the scorching early start, and striking out a lot more than you'd like, but he has enormous raw power (.551 slugging this year) and enough ability to hit to see him as a middle-of-the-order bat down the road with a .260-.280 average but 30-40 jacks.
