Harry Dalton, general manager of the Milwaukee Brewers, confirmed yesterday that his $50,000 fine for comments made to The Washington Post in March had been rescinded earlier this month at baseball's winter meetings.

Dalton was fined under baseball's prestrike "gag rule" for making a statement construed as contrary to management's best interests. Dalton, who had served for nine months on a joint player-management committee studying the issue of partial compensation for a team losing a free agent, had said, "I hope that management is really looking for a compromise and not a 'victory' . . . I hope we're not about to witness another macho test of wills."

The current Sporting News, citing sources, reported that Dalton's fine, imposed by the owners' Player Relations Committee, had been canceled. The News added that neither Dalton nor PRC boss Ray Grebey would confirm it.

"Yes, that's correct," Dalton said yesterday when asked if the fine had been canceled. "It's wonderful news.

"I think they (the PRC) overreacted badly in this case. Let's just say I'm glad it's over."

Asked if he thought baseball, when the game faces its next labor negotiations in 1984, still would have a gag rule such as the bylaw that now allows the PRC to unilaterally assess fines of as much as $500,000, Dalton said, "Let's let sleeping dogs lie."
