Michael Saunders (oblique) took batting practice Wednesday and could be on a rehab assignment as soon as the weekend. Mariners manager Lloyd McClendon said Saunders still isn't swinging at 100 percent and that "it's going to take some time," but McClendon had hopes Saunders will be advanced enough to begin a rehab assignment this weekend. Saunders has been on the disabled list since July 11 due to an oblique strain. He was hitting .276/.327/.434 before the injury.
