CLEVELAND – Contrary to a rumor that originated yesterday on Wall Street, Darryl Strawberry is alive and well.

Word that the former Met and Yankee slugger had been found dead in a Florida hotel room roared through Tampa and the baseball fraternity to the point at which the Yankees’ switchboard was getting calls seeing if it were true.

“I am here in Orlando at the amusement park with my wife and children,” Strawberry told The Post late yesterday afternoon from Disney World. “I am fine.”

Asked if he heard the rumor of his death, Strawberry, who has battled substance abuse for years and was released from prison in April after serving 18 months for violating probation on coacaine possession charges, said he had.

“I was at home [in Tampa] sitting on the couch with my kids when Ron [Dock] called me and told me,” Strawberry said with a laugh. “I don’t know where that came from at all because I am fine. Everything has been good, real good.”

Strawberry is involved with Dock, who works in the Yankees’ system dealing with substance-abuse problems, on a daily basis by attending meetings and talking to kids.

When Strawberry was released from prison, George Steinbrenner had a job waiting for him at the Yankees’ minor-league complex working with young hitters and telling them about the pitfalls that are out there in life.

Strawberry believed he needed time away from baseball in order to adjust to life on the outside. Instead, he has been speaking to Boys & Girls Clubs in Tampa, and last week talked to 200 kids at the YMCA in St. Petersburg.

“I am trying to start a foundation with my church [Church Without Walls in Tampa] that will work with kids to teach them about life and drug abuse,” Strawberry said.

“Everything is going good with that and with me. I am fine.”
