According to Larry Stone of the Seattle Times, free agent outfielder Ken Griffey Jr. is "believed to be looking for a one-year deal in the $5 million to $6 million base salary range, would pay for himself with the boost in attendance he would provide." I'm skeptical on both fronts - that Griffey expects that kind of base salary and that he'd drive that much extra revenue. UPDATE: Just realized that ESPN's Jerry Crasnick had this same info in his January 27th article.
Griffey seems to be the Mariners' backup plan, as they're currently trying to move money to pay for Bobby Abreu or perhaps Garret Anderson (the Twins have "lost their appetite" for Jarrod Washburn trade, says Joe Christensen). Trading for an outfielder is another viable option for Seattle, and if it's for an affordable player they might not have to unload salary. Griffey's agent Brian Goldberg admitted that his client is the fallback option for several teams.
Griffey is open to playing anywhere, but his friend Harold Reynolds said, "I know he'd love to be back [in Seattle]." Reynolds added: "I think they need to do it. He's such an icon to the game of baseball. He's going to play one more year, maybe two at the most. He needs to retire as a Mariner. He's still got something left. I think he'd be fantastic for that team."
