Per Jayson Stark at ESPN:
Well, it's official. The Mark Teixeira auction is on. According to an executive of a club that spoke with the Braves' brass Monday afternoon, they have begun informing other teams they plan to trade Teixeira this week if they get the right deal. The four teams that so far have expressed some level of interest: Diamondbacks, Rays, Red Sox, Angels.
Add to this nugget the fact that the Braves placed Tim Hudson on the disabled list in what seems like mainly a precautionary measure. This is not the action of a team trying to win ballgames.
Thursday at 4pm... it's going to be a fun ride!
