According to MLB.com’s Joe Frisaro, the Marlins are looking to acquire a righthanded reliever and a veteran catcher. Frisaro says indications are that the Fish are "not serious" about Paul Lo Duca.
Possibilities at catcher include Paul Bako, Yorvit Torrealba, and Michael Barrett (in my estimation). Back in November, the Marlins had interest in Torrealba and Barrett.
Possible righty relievers: guys like David Weathers, Chad Bradford, LaTroy Hawkins, and Mike MacDougal. I don’t see the Marlins chasing bigger fish like Huston Street and Jon Rauch. There are no reports indicating it, but I’d like to see the Fish go after Trevor Hoffman (an original Marlin).
