7:19pm: Mike Sweeney has made the Mariners' Opening Day roster, writes Morosi. The 36-year-old was set to retire if he didn't make a team's Opening Day squad. Sweeney will be in a designated hitter platoon with Ken Griffey Jr.
Meanwhile, a source tells Morosi that the Rangers' current interest level in Garko isn't high.
5:10pm: The Mariners have put Ryan Garko on waivers, according to Jon Paul Morosi of FOX Sports (via Twitter). Seattle signed the first baseman to a one-year, $550K deal roughly two months ago. The 29-year-old still has options remaining.
Morosi points out that the Rangers are in search of a right-handed bat, though he is unsure if they are interested in Garko. Texas is in search of a backup corner infielder and although manager Ron Washington seems willing to give middle infielder Andres Blanco a chance at third, it is unlikely that Garko is up to the task. Before he landed with the M's, the Rangers were said to be interested in Garko's services.
In 40 games (127 plate appearances) for the Giants last season, Garko hit .235/.307/.330 with 2 HRs.
