Davey Johnson disagreed yesterday with a published report that said he would quit as manager of the New York Mets unless he receives a contract extension.

The New York Times reported that Johnson has intimated to friends that he does not want to run the team next season as a lame-duck manager. He is in the second year of a three-year contract and, according to the newspaper, the Mets have not been willing to extend the contract.

Johnson said, "I have read the article and I disagree with a lot of the things that are in there. It's true that I would like to have it renegotiated, and it's also true that we've had our differences, but I don't think it's anything that can't be worked out."

General Manager Frank Cashen, who hired Johnson prior to the 1984 season, elevating him from Class AAA Tidewater of the International League, confirmed that Johnson did "broach the subject" of a contract extension.

"I really don't have any comment on it," Cashen said. "I'm trying to win a pennant, not negotiate somebody's contract at this time. You can take all the quotes that were in that story and apply them to last season."
