The Marlins remain willing to trade RHP A.J. Burnett even after placing RHP Josh Beckett on the disabled list for the ninth time in four seasons. The Orioles are willing to include RHP Hayden Penn in a package for Burnett, but the Marlins want more established RHP Daniel Cabrera, whom the O's won't trade. The White Sox could start their package with Class AAA RHP Brandon McCarthy and reliever LHP Damaso Marte. Or they could include prospects instead of McCarthy, which would enable the Marlins to spin those youngsters for a veteran starter. The Orioles, Tigers and Blue Jays are among the teams that likely would pursue Burnett as a free agent this offseason. . . .
