Motter (back) will play second base and bat seventh in the lineup in Monday's Cactus League game against the Royals, Bob Dutton of the Tacoma News Tribune reports.
Motter was sidelined for a few days of camp with a sore back, but his return to the lineup Monday suggests it was only a minor issue. The 27-year-old is expected to vie for a utility role with the Mariners during spring training, primarily competing with Shawn O'Malley for those duties.
