Hello folks.  I am a Mariner fan who recently drafted the Padres in a dynasty league.  I know fairly little about the MLB team and next to nothing about the farm system.  So i come to the experts to help me decide which 8(I have already chosen 7) MLB players I should keep, and which 15 prospects I should keep.  
Here is what I have so far.
