Agreed with your desire for fairness to Pagan, disagree with your assessment. Pagan has a -.27 WPA. I would call that reasonably effective in very low leverage. The problem is, he’s a veteran reliever, Rocco needs the minor league/quad A development pipeline to be those reasonably effective low leverage relievers to try to turn them into effective high leverage relievers.
Sands, Winder, Deleon they should be the low leverage guys who become high leverage some day.
Pagan needs to succeed under pressure or get DFA’d, but they don’t have anyone chomping at the bit to take his place.
