Mariners righty Hisashi Iwakuma is not progressing as had been hoped, as Ryan Divish of the Seattle Times reports. Following another setback, he has received cortisone and platelet-rich plasma injections in his troublesome right shoulder.
The hope, of course, is that this course of treatment will spur healing and finally allow Iwakuma to maintain steady progress. But the expectation had been that the veteran starter would long since have advanced back to the majors.
Seattle’s rotation is in better shape now than it has been at times, with Felix Hernandez and James Paxton returning and rookie Andrew Moore showing well in his first two MLB starts.
