I’ll be slightly shaking up the system for this area in the second part - the “will be” section. Because there seems little point in asking who are going to be the starting pitchers on the 2019 Arizona Diamondbacks Opening Day roster. Barring poor health, it seems all but certain to be Zack Greinke. Robbie Ray, Zack Godley, Luke Weaver and Merrill Kelly. The questions are more to do with depth, because it’s always worth remembering, we’ll need more starting pitchers than five. The chart below shows the number of starting pitchers used by the D-backs each season, and the number of starts made by those outside the top five most used in that role.
