Multiple reports are putting John Lackey in Boston for "AJ Burnett" kinda numbers (~5yrs., ~$85 million). He is said to be in Boston for a physical today.
Meanwhile, the more interesting deal from the Braves perspective is the report that Halliday's agent is in Philadelphia for the purpose of negotiating a long-term contract extension for the Blue Jays' ace. The report (heard on XM radio from other sources) puts Halliday in Philadelphia with Cliff Lee perhaps going to a third (unnamed) team. Apparently, Lee is not cooperating enough with the Phillies in getting a long-term deal for him (Lee is signed through 2010). Clearly, if the extension discussion is underway, then Toronto would have already signed off on a Halliday deal. From the perspective of the Braves, I'd have to know what else is going on with this deal, but if it's effectively a Lee-for-Halliday swap, then it's a 'no real harm done' deal. The worst-case scenario for Atlanta would be if both pitchers were in the Phillies rotation for 2010, but that appears not to be the case.
Also: Matsui to the Angels... one year, about $6.5 million.
No words about Lowe at this time, but presumably, he would be next on the list.
UPDATE: Another domino has fallen: AP reports that Mike Cameron has signed with Boston. (7:53pm, MLBTR). Ken Rosenthal adds that "the Deal is in the range of $15.5MM for two years." Interesting numbers.
