• Hisashi Iwakuma played flat-ground catch on Friday and will have a similar session Sunday before graduating to throwing off a mound at midweek, as he works his way back from a sprained tendon in his middle finger. The All-Star right-hander will need to throw several bullpen sessions and then do a Minor League rehab stint to build up his arm strength, so he likely won't be ready until late April or early May, if all goes well.
• The Mariners became just the sixth team in MLB history to have five starters from different countries make their first five starts of the season. Felix Hernandez (Venezuela), Erasmo Ramirez (Nicaragua), James Paxton (Canada), Roenis Elias (Cuba) and Chris Young (United States) make up Seattle's opening rotation.
