Last year, I created the MLB Draft Rankings Database, in which you can view 2017's here. It was an excellent resource to track draft experts thoughts on where college and prep players rank heading into the June Draft. For 2018, I have brought back the database for our Patreon supporters where you can see how each publication lists the prospects. Fun to see who is high and who is low on the same player. The rankings are compiled and then averaged out in which I create an average rankings list. If you would like to see the fine details, please sign up to be a Patreon supporter and you will receive a link to view the database.
We'll be streaming our MLB Draft reactions on June 4th covering both the first and second round this year on mixlr.com/soxmachine. With the major public publications releasing new MLB Draft Rankings, here is the first Top 50 average prospect rank for the upcoming 2018 MLB Draft.
