Mariners activated OF Victor Robles from the 10-day injured list.

Connor Joe was optioned to Triple-A Tacoma as a corresponding move. Robles has been sidelined since early April with a strained pec. He began the year in a weak-side platoon role with Luke Raley in right field. Joe had been filling that role lately, so expect Robles to slide right back into it. Seattle visits the Royals for a three-game set beginning Friday, with left-hander Noah Cameron set to toe the rubber for KC.
