Well, whoever called it called it. It seems John Henry confirmed in an email to the Associated Press that Matsuzaka's on a plane back to Boston with the rest of Team Red Sox Front Office. Boras said he wouldn't allow it without at least a preliminary agreement. Seeing as the last word was that they had agreed on length, but were just $3M/year apart, it's not totally inconceivable. Haven't looked for a link, but they're talking about it right now on ESPNews.
I love it when Steve Phillips looks stupid.
