The Angels are on Burnett's no-trade list, so he would have to approve the deal. The Pirates and Yankees have been in negotiations over Burnett. New York is not thrilled with the offer that has been made, but the Yankees will take what they can get at this point.
Their only hope was that another team would come along to increase the Pirates' offer.
If Burnett approved the Angels, then the Pirates would have to step their game up. The Yankees might be opposed to Burnett going to another American League team, but they could use the Angels as bait.
Burnett wanted to stay on the East Coast, but the potential to win in California is much greater than in Pittsburgh.
It is only a matter of time before Brian Cashman deals Burnett.
It might cost a bit more, but it would seem like a better deal for the Yankees to send Burnett to the National League.
