Chris Coghlan left Saturday's game with a back strain stemming from a diving catch on Friday. Coghlan won't play Sunday and it's possible he could be out longer. Emilio Bonifacio took over for Coghlan and manager Edwin Rodriguez said Bonifacio would start Sunday and bat leadoff.
Coghlan said he felt discomfort while taking batting practice before Saturday's game but felt okay to play. Rodriguez detected an awkward swing when Coghlan struck out swinging in the fifth and decided to take him out.
The Marlins also announced after the game that Mike Lamb, their lefty pinch-hitter off the bench, will be designated for assignment, effective Sunday. He'll be replaced on the roster by outfielder Bryan Petersen, who was with the Marlins earlier in the season and is hitting .259 at Triple A New Orleans.
