The Seattle Mariners are expected to promote Jesus Montero in time for Thursday night's game.

Michael Saunders has landed on the disabled list with an injured right shoulder, creating a roster spot.

The 24-year-old was not in the lineup for Triple-A Tacoma's game on Thursday morning in Memphis.

Montero was hitting .270 with 15 doubles, one triple, eight home runs and 40 RBIs in 59 games with Tacoma, with a .465 slugging percentage and .800 OPS.
