On this wacky, topsy-turvy day, Gonzalez and the Red Sox have apparently reached an agreement on an extension and the trade with the Padres is on again.
No terms have been announced yet. Press conference is scheduled for tomorrow.
UPDATE (8:36 PM): From Extra Bases:
It appears the deal was done without an extension. Look for the Red Sox to come to an agreement, but not announce it until after Opening Day. That would allow them to save millions on the luxury tax.
It is likely that the Red Sox and Gonzalez have an understanding of what the extension would be, otherwise it would be risky to trade three prospects for one year out of the first baseman. This is basically what happened with Josh Beckett last spring. There was a deal in place that was announced after Opening Day.
It also would allow them to make sure Gonzalez recovers from the surgery he had on his right (non-throwing) shoulder. But that is not a major issue.
Just for the record, the trade is still Gonzalez for Casey Kelly, Anthony Rizzo, Rey Fuentes and a player to be named later. That would indicate to me that the Sox feel an extension is in place.
