Diamondback's pitcher Robbie Ray is slated to start the second game of the season. With the injury to Zack Greinke, the Diamondbacks have had to re-shuffle their rotation, putting Patrick Corbin on Opening Day, with Greinke likely sliding to third in the rotation. Have Ray pitch the second game allows him to maintain his usual schedule. Ray has the skills to be a borderline elite arm all season long, but a game against the Rockies is a tough test to start to the season.
