Mariners placed RHP Emerson Hancock on the 15-day injured list, retroactive to August 29, with a left adductor strain.

Hancock suffered the injury during Friday’s start against the Blue Jays. He’s going to miss at least a couple of weeks. It’s unclear if the Mariners will continue to operate with a six-man rotation in his absence, or if they’ll revert to a traditional five-man alignment.
