The above list is obviously flawed, as are all such lists.
This list of position players is based solely on offense, and Martinez clearly had the best offensive numbers of all our MIF prospects.
Since so many of our MIFs played multiple positions, the list can put them about anywhere in the infield.
Personally, my picks would have been Martinez and Rocchio at the keystone, with Fry (who played most of his games there) at third. Tena and Arias didn't put up the offensive numbers of Martinez, Rocchio, or Fry.
In the outfield, Noel over Benson is another faux pas.
It's a list of who had the best minor league season, not who is the best prospect...and since its only one choice per position, other prospects with solid years don't get mentioned.
Pries...and Fry...won their positions by default, although they both had good years.
