Iwakuma said his shoulder felt fine after Saturday's bullpen session, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Saturday's marks the first time Iwakuma has tossed a bullpen since landing on the disabled list. Although the right-hander wasn't overly excited with the session, it was a big step in working his way back to the big-league rotation. He's set to throw another bullpen in the next couple days, at which point there should be a clearer timetable for his return, though mid-June still seems like the earliest possibility.
