You don't need to fake any injuries. Anyone on the 40 man roster can be part of the playoff roster. Adrianza can play all over the field and take this situation into account. 9th inning, tie game, 1 out and Miguel Sano is standing on 2nd base. Adrianza is your guy. This is a much, much, much more likely scenerio than ever having to use a 13th pitcher in a 5 game series.
