Marlins optioned OF Bryan Petersen to Triple-A New Orleans. Petersen didn't exactly play poorly this spring, batting .250 (11-for-44) with a homer and four stolen bases, but sometimes having options left works against you at this time of the year. Austin Kearns and Chris Coghlan now both have a pretty good shot to be with the team on Opening Day. The Marlins also reassigned right-hander J.D. Martin and infielder Nick Green to minor league camp.
