M's add Rodriguez, Langerhans to roster

SEATTLE (AP) - The Seattle Mariners have finalized their opening day roster by adding infielder Luis Rodriguez and outfielder Ryan Langerhans to the 25-man roster.

Seattle made the moves late Wednesday night after its final exhibition game against the Los Angeles Dodgers. The Mariners open the season tonight (7 p.m., ROOT, KVNI 1080, KXLY 920) at Oakland.

Reigning Cy Young Award winner Felix Hernandez is scheduled to get the start on the mound for Seattle, under first-year manager Eric Wedge.

The Mariners also placed starting center fielder Franklin Gutierrez on the 15-day disabled list with stomach gastritis. He's joined on the 15-day DL by closer David Aardsma, who continues to recover from hip surgery, and infielder Matt Mangini, who has a strained right quad. All three moves were retroactive to March 22.

Seattle placed left-hander Mauricio Robles and right-hander Shawn Kelley on the 60-day DL. Each will be eligible to return on May 30.

As of today, Fox Sports Net Northwest becomes ROOT Sports, with the games on the same channels as they were under FSN Northwest.
