Bryan Peterson - Marlins OF Prospect

Bryan Peterson, 22, of the marlins was recently promoted to AA Carolina. He was drafted by the marlins in the 2007 draft. He was hitting .301 with 19 hr, 58 rbi, and 15 sb in high A to go along with a .922 ops.  At AA he is off to a hot start hitting .471 with 6 rbi in 13 ab.

What are everyones thoughts on this guy as I have not heard of him until today. Is he a legit prospect or just a mirage? What was said about him before the draft?
