A major league spokesman says "more names are involved" in an investigation of Pittsburgh-area cocaine trafficking in which all-star outfielder Tim Raines has followed three current or former Pirates in providing grand jury testimony.

Raines left the Montreal Expos' camp in West Palm Beach, Fla., to appear in Pittsburgh. In 1982, he admitted using cocaine and spent time in rehabilitation.

There have been published reports that up to a dozen more players could be subpoenaed. The probe reportedly centers on who supplied cocaine to major leaguers, not recipients.

Pirates outfielder Lee Mazzilli, who with Rod Scurry and Dale Berra testified earlier this year, told The Press that "I hope they nail him" -- the unnamed alleged target of the investigation . . .

Joe Pepitone, the 1960s New York Yankees' flamboyant first baseman-outfielder who later played for the Astros, Cubs and Braves, has been arrested in Brooklyn on charges of possessing more than four ounces of cocaine and a .22-caliber pistol.

The car in which Pepitone, 44, of Brooklyn, was riding with two other men was stopped after it allegedly ran a red light in the Brownsville section. A search of the car turned up a five-shot derringer under the front seat, some unidentified pills and an eighth of a kilo of cocaine, authorities said.
