Duvall declined his portion of his $7 million mutual option Thursday, Craig Mish of SportsGrid.com reports.
EDGE Analysis
Duvall's decision to decline his option isn't surprising, but Atlanta will be able to tender him by Dec. 2 since he's eligible for arbitration. The 33-year-old appeared in 146 games between Miami and Atlanta this year and hit .228 with 38 home runs, 113 RBI and 67 runs.
