Mariners activated C Miguel Olivo from the 15-day disabled list.
Olivo was cleared to return after playing three rehab games with Triple-A Tacoma. The veteran backstop returns to a .210/.229/.346 batting line over his first 84 plate appearances this season. He should get the majority of the time behind the plate moving forward, with Jesus Montero getting most of his at-bats of the DH spot again.
