Twenty Hall of Famers, including Hoyt Wilhelm, Enos Slaughter and Lou Brock, the most recent inductees at Cooperstown, will be among 60 former Major League baseball players on the field July 1 in the fourth annual Cracker Jack Old Timers Baseball Classic at RFK Stadium . . .

Larry Bowa, the Chicago Cubs' frustrated backup shortstop, has formally asked to be traded, said Dallas Green, the team's president and general manager.

Green said Bowa's agent, Jack Sands of Boston, made the request on behalf of his client. "I don't know that I can better the situation for Larry Bowa . . . at 39 years old," Green said.

Bowa lost his starting job to rookie Shawon Dunston in spring training . . .

The New York Yankees have agreed to try to honor outfielder Ken Griffey's request to be traded, General Manager Clyde King said.

King said Yankees owner George Steinbrenner "has given me permission to go ahead."

Griffey has been platooned in left field with Billy Sample since Billy Martin took over as Yankees manager from Yogi Berra April 29. Griffey had sat out the previous three games against left-handed pitchers.

In 18 games, Griffey is batting .277 . . .

U.S. Attorney J. Alan Johnson refused in Pittsburgh to confirm reports that federal indictments are imminent in an investigation of drug trafficking that is said to include prominent baseball names. Several players testified before a grand jury in recent months . . .

Baseball Commissioner Peter Ueberroth said the sport "must, has to, and will" eliminate drug abuse to set an example for the rest of society.

"Let me clearly say that other sports have the problem equally as bad or worse," said Ueberroth, keynote speaker of an Associated Press luncheon at the American Newspaper Publishers Association convention in Miami Beach. "But baseball must rid itself (of drugs), first for the well-being of the players . . . and because baseball is an example for young people."
