It comes back to roster decisions made last November. Literally, the first decisions made by Falvine. The decision was to start the offseason with only 8 starting pitchers on the 40 man (counting May AND Duffey) who had ever pitched above AA. Santana, Santiago, Hughes, Gibson, May, Mejia, Duffey and Berrios. Given the health and performances of those 8 in 2016, that was shortsighted to say the least. Injuries and unexpected poor performance are part of baseball. Although, I don't consider the poor performances by any of the pitchers to be "unexpected". Point being if your plan is to only use guys from the 40 man to help, you better be sure those guys CAN help. Like I said, no plan from day one.
