Johnson most likely will take his physical today, and the trade probably will be finalized tomorrow. Arizona general manager Josh Byrnes confirmed the agreement but otherwise declined comment until after the medical information is reviewed.

New York, which acquired the Big Unit from Arizona two years ago, would receive reliever Luis Vizcaino, minor league right-handers Ross Ohlendorf and Steven Jackson, and minor league shortstop Alberto Gonzalez.

"We're very excited and very happy for Randy, We think it's a win-win for everybody," said Alan Nero, who represents Johnson along with Barry Meister. "It was very complex because there was a lot of legal work — it was the third time the contract has been redone. Other than that, I think it went very smoothly."
