The Mariners recalled first baseman Justin Smoak from Triple-A Tacoma, the team announced on Friday after placing outfielder Michael Saunders on the 15-day disabled list.
The 27-year-old Smoak, who was in the Mariners' lineup for Friday's game against the visiting A's, was initially sent down on a rehab assignment after he was put on the disabled list with a strained left quad on June 11. But Seattle opted to keep him there and go with Logan Morrison at first base.
Smoak is expected to fill in at first base and designated hitter. The five-year veteran was hitting .208/.282/.361 with seven homers and 29 RBIs in 63 games this season.
Saunders, who was hitting .276 with six homers and 28 RBIs in 65 games this season, strained his left oblique on Thursday.
