heh, that sounds like some sort of wrestling promo....
That sort of sounds like the Sox haven't jumped in on him yet, so if he decides tonight, they wouldn't get a chance to.
Of course all these options means he won't be here, but one could take it the comment like he's going to sign with an AL Central team. Won't be the Tigers, no way he takes a back-up role in Minnesota, unless he's going to be a DH or something bizzare like that. Royals, he can sign with them for all I care, won't hurt the Sox one bit.
That's all I can think of in terms not being good news for the Sox, I'm guessing they haven't talked with him, or made up their minds whether or not to persue him.
