Mariners placed OF/1B Logan Morrison on the 15-day disabled list, retroactive to April 15, with a right hamstring strain. Morrison actually suffered the injury on Monday before he took an at-bat or went to his position. It's not clear at this point how long he might be sidelined. LoMo was off to a .150/.227/.150 start with no homers and no RBI in eight games so far this season.
