The Rockies signed catcher Omir Santos, according to their team website. The 31-year-old elected free agency last week after the Tigers designated him for assignment.
Santos appeared in three games with Detroit this month after the Tigers promoted him from Triple-A Toledo, where he had a .310/.315/.417 batting line in 89 plate appearances. Santos also appeared in 11 games with last year's Tigers team and has MLB experience in four seasons. He is a Praver/Shapiro client.
