www.minorleagueball.com does a Top 50 prospects list for all of mlb. See this link for an example. The way it works is that any prospects eligible for a position are put in the comments section and readers put a +1 after the prospect they like.
After a prospect wins, that prospect assumes the position on the list and is eliminated from further votes.
For the #1 position I will just use the Top 4 from Pikachu's list
Further positions will have more options, but the top positions are a bit clearer. A discussion comment will be placed at the end and any discussion should happen after that. The first 4 options will be D'Arnaud, Gose, Hutchison, and Marisnick (alphabetical order)
It has been suggested that we use Rec's rather than +1's. Please 'rec' the prospect you like. The +1's will be ignored.
