Baseball Commissioner Peter Ueberroth has summoned 24 players who have been involved with or implicated in drug-related matters to meetings at his office in January.

The New York Times reported yesterday that Ueberroth sent letters to the 24 players.

Nineteen of the 24 were among those who testified or were named during the Pittsburgh drug trial of Philadelphia caterer Curtis Strong. The other five have admitted involvement with drugs, The Times said.

Those receiving letters who testified at the Strong trial were Dave Parker, Keith Hernandez, Dale Berra, Lonnie Smith, Jeff Leonard, Enos Cabell and John Milner, who is no longer an active player and could refuse the commissioner's summons.

Those summoned who were mentioned during the trial but did not testify were Joaquin Andujar, Rod Scurry, Bill Madlock, Gary Matthews, Lee Lacy, Tim Raines, Al Holland, Dusty Baker, Lary Sorensen, Derrel Thomas, Dickie Noles and Manny Sarmiento.

Also receiving letters from the commissioner's general counsel, Ed Durso, were Alan Wiggins, Daryl Sconiers, Claudell Washington, Mike Norris and Vida Blue, all of whom have undergone drug rehabilitation, as have several of the other players.

Don Fehr, head of the Major League Baseball Players Association, said of Ueberroth's action: "This is not a surprise, since he indicated a while ago that he wanted to hold these meetings. I don't know what took so long to have them.

"We will be interested in seeing how they are handled, if they will be conducted with integrity or if this is going to be about publicity. We hope it isn't."

The players who testified at the Strong trial did so with immunity against prosecution, and all of them testified that they had ended their drug use.

There was no indication what, if any, action could be taken against the players summoned.
