need to know more than that to know what your asking. you only keep one player?
if that is all you keep you have to keep the highest ranked player you have.
It looks like that might be bautista at #30 or sherzer at #33. max might be a better keep since he probably will be a top 10 SP and bautista probably will not crack the top 10 OF, let alone hitters
I would hate to keep either one when the rest of the teams will keep guys like trout, miggy etc
you better hope you can draft better than them or you will be playing catch up all year
