The Mariners will send Jason Vargas (14-10, 3.92) to the mound, who has won just one of his last five starts while posting a 6.35 ERA during that span. Vargas has been better at home lately, owning a 5-4 record with a 2.62 ERA at Safeco, including a 3-1 mark with a 2.06 ERA in the last six played there.
Texas will counter with Ryan Dempster (6-2, 4.70 ERA), who was roughed up in his last outing. He allowed five runs, six hits and three walks in just 3.1 innings of work on Tuesday en route to a 11-3 loss to the Angels. Dempster is facing Seattle for only the second time, with his last coming on July 22, 2010, a 2-0 loss to the Mariners.
First pitch is set for 1:05 p.m. PT with coverage on Fox Sports Northwest and ESPN 710 AM.
