Dave Stewart becomes a 20-game winner when the A’s beat Cleveland at Oakland-Alameda County Coliseum, 4-3. The thirty year-old right hander, who spent the first decade of his career in the bullpen, will also earn twenty or more victories in the next three seasons.

Trying to circumvent the Mariners’ ‘escape clause,’ which is based on attendance at the Kingdome, the King County Council attempts to modify the deal it made with the team.

The 7th-place Brewers end their season with a 4 – 0 win over the Blue Jays, and manager Rene Lachemann bows out. Lachemann had been fired earlier in the week but stayed on till the finish. George Bamberger will return as manager of the Brewers in 1985.

The ML umpires announce that they will go on strike at the two LCS scheduled to begin October 2 in an effort to improve their pay and job security and to change the method by which post-season assignments are determined. MLB officials say the games will go on as scheduled using amateur umpires if necessary.

Padre Eddie Miller and Dodger Tony Brewer hit homers in their last major league at bats. Miller’s 9th-inning four-bagger, his only career homer, comes in a 4 – 3 loss to Atlanta’s Pascual Perez, while Brewer, the PCL batting champion, homers in LA’s 7 – 2 win over the Giants.

Phillies manager Paul Owens resigns following a season-ending doubleheader loss to the Pirates and will move back into the club’s front office. Coach John Felske will succeed Owens as manager in 1985.
