According to MLBTR, he is open to resigning with the Brewers. However, he has been linked to teams including the Twins, Royals, Cubs, and Padres within the last few weeks. With their recent trade for Shields and Davis, I don't see the Royals as a contender for Marcum anymore. I see the Twins, Brewers, and Cubs as his most possible destinations, because all of them need a pitcher of his caliber, and I don't see him bolting the Midwest to play for the Padres unless they make him an offer that he can't refuse.
