With the addition of DJ Peters (OF), Mitchell White (RHP), and Zach McKinstry (Utility), the 40 man roster is set. We can all debate as to who we think would have been a better choice to be protected, but I have no quarrel with who was ultimately protected. AF could have influenced by a number of calls for a specific prospect or lack of calls for a specific prospect to drive his selection. He also knows where the team is in discussions for other players (FA or trade) and how that may have influenced the decision.
I have heard and read that both Jordan Sheffield and Cristian Santana are in top tiers to be drafted in the upcoming Rule 5 draft.
