The Marlins signed former big league catcher Mike Rivera and assigned him to Triple A, according to MLB.com's transactions page. Rivera, who turns 34 later this month, has big league experience with the Tigers, Padres and Brewers. He last played in the majors in 2009 and spent most of this season at AA for the Dodgers.
Rivera posted a .257/.384/.377 line at Chattanooga, showing more patience than he did in his big league career (.244/.305/.383 MLB line). The Marlins don't have much depth behind the plate, since John Baker has an injured elbow and Ronny Paulino has been suspended for PED use. We heard last night that they were looking to sign a catcher.
