Mariners' Mitch Garver: Out Wednesday with back spasms

Garver (back) is out of the lineup for Wednesday's game against the Royals, Daniel Kramer of MLB.com reports.

He'll remain on the bench for the second day in a row while he manages upper-back spasms. Mitch Haniger will get a day out of the outfield and serve as the Mariners' designated hitter while Garver rests up.
