The following cheat sheets are a general fantasy ranking of players who are not under the contract of any MLB club and over the age of 18 (ie. not players who would be selected by MLB teams in the annual draft or signed in countries where MLB has relations like the Dominican Republic).
Players are ranked on long-term value for a MLB team, so it leans more toward being a keeper-type cheat sheet.
The first listing is of the top players in the world, regardless of their likelihood of coming to MLB any time soon. The second list ranks the top players who may come to MLB when eligible (usually through the posting system from Japan).
