Baseball Prospectus | Future Shock: Changes In The Wind:
"Dustin Ackley, 2B, Mariners: The second overall pick in the 2009 draft might just be the most interesting defensive case in the minors. He was primary a first baseman during his college career at North Carolina, but that was because he was recovering from Tommy John surgery and couldn't throw. He's a plus-plus runner with up-the-middle athleticism, and while most teams thought center field was his most logical landing spot, the Mariners' initial play is second base, a position he has no experience at. While he's been struggling with his bat at Double-A this year, scouts say he looks surprisingly comfortable with the glove."
