According to an MLB.com article, Pudge has specifically named the Marlins, Astros and Mets as the teams who have shown interest in his services behind the plate.
"I don't know where I'm going to play, but a team is going to win the lotto when I sign. I still feel I can play three or four more years, to be honest, because of the way I take care of myself."
The Marlins and Astros are at their budget (obviously), while Pudge is looking for $3 million. I guess that takes the Astros out of it.
