3 year deal, $24 million. My initial thought was "Jeff Clement, drool." Apparently Buster Olney had the same reaction. (link requires membership...)

"What follows is pure speculation; to repeat, pure speculation. With the Mariners now committed to Johjima for the next few years, it might make sense for Seattle to offer catching prospect Jeff Clement to the Red Sox in return for outfielder Coco Crisp, with other players also involved in the deal; the Red Sox would have to include some pitching.

"Boston is looking to improve its catching depth and Clement could give them a solid alternative one day, as Jason Varitek enters the last years of his career, and the Mariners desperately need to stabilize their outfield situation. Crisp could play right field, with Ichiro Suzuki remaining in center, or, if Ichiro preferred right, Crisp could play center."

Never mind that Coco in RF is a ridiculously terrible idea, especially with Ichiro and his arm being relatively wasted in LF. Clement is apparently having a strong season thus far at AAA -

Clement is tearing up the Class AAA ranks for the team's Tacoma affiliate. The first-round draft pick from 2005 is hitting .364 with an on-base-plus-slugging percentage of 1.161 with five home runs and 17 runs batted in over 66 at-bats.

I don't know much about Clement's defense. And I don't know what else it would take beyond Coco. Bowden? Hansen? Anyone but Masterson? Git er done, Theo.
