Cooper agreed to a one-year, $4.2 million contract with the Marlins on Friday to avoid arbitration, Craig Mish of SportsGrid.com reports.
Cooper played a career-high 119 games last season and had a .261/.337/.415 slash line with nine home runs and 50 RBI. The 32-year-old should be Miami's Opening Day starter at first base and is entering his final year before free agency.
