Updating a previous report, Ackley is out of Monday's lineup due to a left ankle concern, Bob Dutton of the Tacoma News Tribune reports. Ackley underwent what was described as a precautionary MRI on Monday, with the results likely to arrive Tuesday. There should be more clarification on the matter at that time, but even if the MRI comes back clean, there's no guarantee Ackley will assume an everyday role in short order. He was enduring a rough spell at the plate prior to coming down with the injury, and with the Mariners activating Michael Saunders (oblique) from the DL on Monday, Ackley could begin to lose out on at-bats if his struggles persist.
