Shelby Miller went under the knife of Dr. Neal ElAttrache in May 2017, and his return was hoped to provide a boost for the D-backs rotation. Before losing the rest of 2017 to injury, Miller had looked as good as he had been in an Arizona uniform, posting a 116 ERA+ over four starts. He began game rehab in mid-May and was deemed ready for action after tossing 6.2 scoreless innings for the High-A Rawhide on June 16, with no walks and ten strikeouts. Nine days later he made his return to the major-leagues, taking the mound for the D-backs against the Marlins in Miami.
