CBS Sports' Danny Knobler reports that the Marlins are telling teams Steve Cishek is unavailable. Miami is also unwilling to part with left-handed reliever Mike Dunn, according to Knobler's sources. Cishek is under team control through 2017 and the Fish probably plan to contend while he's in the fold. Dunn can't hit the free agent market until after the 2016 season.
