Overview
Even before Opening Day, the season was marked with a flurry of change, most notably with the hiring of new general manager Jack Zduriencik, field manager Don Wakamatsu, and an entirely new major-league coaching staff. Unlike the previous season, which was approached with an expectation to contend for the AL West division title, the 2009 season has been approached with a rebuilding philosophy and a departure from the team-building strategies used in previous seasons. In January the Mariners unveiled their 2009 slogan, "A New Day, A New Way", to reflect their rebuilding philosophy.
In terms of players, this season was marked by the free agency departure of outfielder Raúl Ibáñez, who signed with the Philadelphia Phillies, and the trade of closer J. J. Putz to the New York Mets. However, the offseason has been most notable for the acquisition of longtime Mariners outfielder Ken Griffey, Jr., nearly 10 years after trading him to the Cincinnati Reds. Other notable acquisitions have included outfielders Franklin Gutiérrez and Endy Chávez (both from the Putz trade), new closer David Aardsma (traded by Boston Red Sox) and long-time Kansas City Royals infielder Mike Sweeney (free agent).
This season also marks the 10th anniversary of Safeco Field, the Mariners' home stadium which opened its gates July 15, 1999.
