The Red Sox made substantial offers to the Chicago White Sox for outfielder Jermaine Dye and Texas Rangers for relief pitcher Eric Gagne, but as of late Monday night were unsure if both, one or neither would be landed before the deadline passes Tuesday at 4 p.m. Boston would feel comfortable moving forward with their present roster configuration, but Dye and Gagne offer priceless insurance for the pennant stretch if any of the current nicks, bruises and aches deteriorate into long-term absences. Theo Epstein could not be reached for comment, but two other general managers said the Sox have made serious bids to land both Dye and Gagne, although they remained adamant about not parting with top prospects Jacoby Ellsbury, Clay Buchholz or Justin Masterson. There were conflicting reports about the Sox? intent on not discussing Manny Delcarmen, Jon Lester and Portland right-hander Michael Bowden.
