ESPN's Jerry Crasnick reports that the Red Sox are asking for teams' best prospects in trade talks for Andrew Miller. As Crasnick notes, they'll surely have to drop their demands in order to get anything done. Miller is having a fantastic season, posting a 2.40 ERA and 66/13 K/BB ratio over 41 1/3 innings, but clubs aren't going to surrender top talent for him. The Braves, Pirates and Royals have all been connected to the lefty reliever.
