Logan Morrison singled twice and drove in a run Thursday against the Padres. Morrison was lifted after two at-bats, a decent start to Cactus League action for the DH. The Mariners, though, aren't just looking at his ability to be productive, but simply his ability to stay healthy. Morrison has had issues with the patellar tendon in his right knee, forcing him to play in only 175 games since the start of 2012.
