Being a catcher for the Marlins is like being a drummer for Spinal Tap.
The latest future victim is Mike Rivera, who played with Milwaukee in 2009 and has also appeared with the Tigers, Padres and Brewers. Rivera, 35, has been signed and assigned to Triple-A New Orleans, the Miami Herald 's Clark Spencer writes .
Spencer also notes Marlins catcher John Baker will undergo Tommy John surgery on Friday and will miss the 2011 season. The Marlins also have Ronny Paulino serving a 50-game suspension and lost Brett Hayes to a dislocated shoulder thanks to Nyjer Morgan on Tuesday.
