According to MLB.com's Joe Frisaro, the Marlins have told clubs that Steve Cishek is not available. The Fish are also said to be protecting left-handed reliever Mike Dunn, at least for now. Cishek, 26, has a 4.50 ERA, 1.38 WHIP and 21/12 K/BB ratio in 24 innings this season as Miami's primary closer. He doesn't carry that much real-life trade value anyway.
