Mariners' Tom Wilhelmsen: Headed to DL

Wilhelmsen (back) was placed on the 15-day disabled list Saturday, Bob Dutton of the Tacoma News Tribune reports.

Analysis:

Reports surfaced Friday that Wilhelmson was dealing with a back issue that could warrant a DL stint, and Saturday's announcement confirmed that suspicion. The Mariners recalled first baseman Dae-Ho Lee from Triple-A Tacoma to fill Wilhelmsen's roster spot. With Wilhelmsen down, the Mariners have an extremely shallow bullpen corps that could need reinforcements in the coming days, however.
