Pitchers Tom Browning and Rick Mahler have joined Danny Jackson and Bill Doran as members of the World Series champion Cincinnati Reds who have filed for free agency.

Browning was 15-9 with a 3.80 ERA and made $2,125,000 this season. He was the winning pitcher in Game 3 of the World Series against Oakland.Bob Welch of the losing Athletics, the first 27-game winner in the major leagues since Steve Carlton in 1972, also filed for free agency Thursday along with eight other players, bringing the total to 59.

Welch was 27-6 with a 2.95 ERA in 35 starts. The right-hander, who will be 34 next week, made $1 million this season and could become one of the highest-paid pitchers in baseball. He intends to represent himself in negotiations and not use an agent.

Others filing Thursday were Baltimore first baseman-designated hitter Ron Kittle, California infielder Donnie Hill, Houston relief pitcher Juan Agosto, Minnesota outfielder-DH Randy Bush, Montreal pitcher Dave Schmidt and Philadelphia pitcher Don Carman.

The Orioles have until Dec. 15 to exercise a 1991 option on Kittle.

The San Diego Padres prevented first baseman Jack Clark from becoming a free agent by offering him salary arbitration. Several other players did not hear from their teams by Thursday's midnight deadline and are eligible for free agency.

Among those who could be free are second basemen Willie Randolph of Oakland and Pittsburgh's Wally Backman, St. Louis pitcher Tom Niedenfuer and Seattle outfielder-first baseman Ken Griffey Sr. The New York Mets reached a one-year agreement with second baseman Tom Herr on Thursday night.
