I don't know about an extension. We want to go younger, not older. Jose's great, but at his age, any kind of an extension worth more than $5 million per for two or more years is out of the question. He's a great guy to have here for Alexei and Dayan in the future, but he's not 27, he's 37.
Plus, if he really finishes off the season well, he may get picked up by some other team for a good amount of money on a short term deal. I don't think the Sox are going to pursue him if that happens.
