The Diamondbacks biggest question going into 2017 is how the starting rotation will bounce back. The team was looking towards big things with a starting five of Zack Greinke, Shelby Miller, Patrick Corbin, Robbie Ray, and Rubby De La Rosa. Of this group, four of those five starters are penciled in for the 2017 rotation and the 5th spot going to Taijuan Walker. All six of the aforementioned pitchers struggled in 2016 while also making big strides that give reason for optimism in 2017.
Zack Greinke: Greinke’s biggest issues in 2017 were injuries that limited him to 158 1⁄3 IP over 26 starts.
