Crawford (finger) will begin a minor-league rehab assignment with Triple-A Tacoma on Saturday, Tacoma broadcaster Mike Curto reports.
Crawford took batting practice with the Mariners on Friday and was sent out on a rehab assignment afterward. The shortstop has been on the shelf since July 24 with a hairline fracture of his right pinky finger and it's unclear how many rehab outings he'll require before being activated.
