Bobby Cox, who managed the Toronto Blue Jays to the 1985 American League East Division title, has resigned to become general manager of the Atlanta Braves -- a club that fired him four years ago.

The move was announced tonight by Blue Jays General Manager Pat Gillick, who is in St. Louis for the World Series.

"This organization is the only one I would have left Toronto for," Cox, who lives in suburban Marietta, Ga., said in a telephone interview. "Atlanta's my home, and I'll be able to spend more time with my family."

He said he had "basically" a five-year deal with the Braves.

Chuck Tanner, the Braves' new manager, said the acquisition of Cox gave the Braves "the most solid situation Atlanta has been in in a long, long time."

Braves spokesman Wayne Minshew said an announcement would be made Tuesday in St. Louis.

Jimy Williams, the Blue Jays' third base coach, is considered a possible replacement for Cox, but Blue Jays spokesman Howard Starkman said it was "too early to comment" on the situation.

Cox managed the Braves from 1978 through 1981, but was fired after Atlanta posted a 50-56 record in the strike-shortened 1981 season. He moved to Toronto in 1982 and guided the team to its first division title this season.
