From Gordon Edes of the BG’s Extra Bases blog:

The Red Sox and Twins are through negotiating for now, Both Sox GM Theo Epstein and Twins GM Bill Smith have called it a night, but momentous news may await in the morning. As Amalie Benjamin reported an hour ago, the sides have exchanged medical information on pitcher Jon Lester and Johan Santana, indicating that a deal may be in place.

There were indications that the Twins would be getting center fielder Coco Crisp, pitcher Justin Masterson and infielder Jed Lowrie in addition to Lester, the winner of the Series-clinching Game 4 and a favorite of pitching coach John Farrell. But that was not confirmed. Repeat, That has not yet been confirmed. We’re working on it.

Even if an agreement has been reached between the teams, the Sox are expected to request a 72-hour window in which to try and negotiate a contract extension for Santana.

It looks like the Twins seem ready to accept the Red Sox package of players for Santana.  Nothing is done yet, as Gordo clearly warns “Red Sox Nation”, but a deal might snowball relatively fast from here.
