With only five days left until the D-Backs break camp and take the leisurely 25 minute drive to Chase Field for Opening Day against the Rockies, one of the few lingering questions remains: who will take the fifth spot in the starting rotation? At the moment, the D-Backs rotation shakes out (in order) as Zac Gallen, Merrill Kelly, Eduardo Rodriguez, Brandon Pfaadt, and one of Tommy Henry, Bryce Jarvis, or Ryne Nelson. That calculus could certainly change depending on how Rodriguez’s “lat tightness” proceeds in the coming days, but Torey Lovullo et al seemed cautiously optimistic after the game about his availability for the Opening Day rotation.
