MIAMI -- The Miami Marlins say Dan Jennings is returning to his former job as general manager after moving to the dugout as manager this season.

Marlins President David Samson said Tuesday the search for a new manager has begun. Candidates include former major league managers Manny Acta, Larry Bowa and Bo Porter.

Jennings made the unusual move from GM to manager when the Marlins fired Mike Redmond after a 16-22 start. The change failed to spark a turnaround, and the injury-riddled Marlins finished 71-91, their sixth consecutive losing season.

Jennings has been with the Marlins since 2002 and is under contract through 2018.
