Iwakuma (shoulder) has progressed to long toss, but remains three-to-four weeks from a potential return, Ryan Divish of the Seattle Times reports. Iwakuma was initially slated to miss two-to-four weeks total, but the new timetable would push the initial one to four or five weeks. A late May return may still be possible at this point, but it's also possible his absence extends into June.
