Jaosn Giambi Close To Signing With A Contender?

Susan Slusser of The SF Chronicle hears that Jason Giambi is "getting close to signing with a contender to be add some bench power, and the team I'm hearing is Colorado." She mentions that the Rockies' interest is unconfirmed. Giambi was released by the Athletics earlier this month while he was on the disabled list, hitting just .193-.332-.364 in 83 games. I would think it's safe to assume he's healthy if teams are interested in signing him.  Not that the sample size is substantial, but Giambi is a career .283-.356-.509 hitter in 59 career plate appearances off the bench. Any team that signs him will only be responsible for the pro-rated minimum.
