The Dodgers have opened talks with Ned Colletti on a contract extension.

Mark Walter, the team's chairman, said he did not know the details of the discussions but confirmed a new deal is on the table.

The guaranteed portion of Colletti's contract expires at the end of the season.

The Dodgers are more than four games back of the Giants in the National League West despite a flurry of big-name addition in July and August.
