Is Santana Claus Coming To Town?

Apologies to Boston Dirt Dogs for the headline. The news this morning on the Sox' pursuit of Johan Santana contains a few new wrinkles, namely that the teams swapped medical reports (on Jon Lester and Santana) last night, and that the proposal in place - Lester, Jed Lowrie, Justin Masterson, and Coco Crisp - might be enough to get it done. One report mentioned that the Twins are extremely high on Masterson, who they view as a future set-up man supreme. I'm sure the updates will be fast and furious today as the dust flies down there in Nashville.
