By all consensus, the starting rotation of the Arizona Diamondbacks has been a disaster. Save the modest 11 wins from Zack Greinke, who also spent nearly a month and one-half on the disabled list, the fall from grace of starters was as dramatic and it was compelling.
Lefty Patrick Corbin, coming off a stellar spring, fell completely from favor and dropped from the rotation. The celebrated Shelby Miller trade turned out to be as shameful as it was tragic.
While there has been a residual effect through the rotation, the emergence of left-hander Robbie Ray to the reaches of Arizona starters was not completely unexpected.
