Makakilo:
Back of rotation: On opening day, my view is that Gallen, Kelly, and Rodriguez are top of the rotation, except that Rodriguez will start the season on the DL. Gallen, Kelly, and Rodriguez rank high on five measures of pitching consistency. After talking with execs/scouts/analysts, this article ranked starting pitchers; Gallen was #10 (tie), Rodriguez #44, and Kelly #45.
Although it seems most likely that the other Diamondbacks who will start the season in the rotation are Ryne Nelson, Tommy Henry, and Brandon Pfaadt, I’m about to consider other possibilities that are less likely.
