They lose to the San Francisco Giants 3-2 at Candlestick Park as the Giants' Milt May hits the game-winning home run off Al Hrabosky in the seventh inning; the loss is Atlanta's eighth consecutive and 12th in their last 13 games. Meanwhile, the Los Angeles Dodgers, who had trailed the Braves by 10 games less than two weeks earlier, defeat the Cincinnati Reds at Dodger Stadium 11-3 as Rick Monday and Steve Garvey both homer. The victory is the eighth consecutive and 12th in the last 13 games for the Dodgers, who had swept two four-game series from the Braves during this comeback—one at Atlanta–Fulton County Stadium at the beginning and another at Dodger Stadium (the first three coming in extra innings) just prior to the Cincinnati series. The Braves had been in first place since winning their first 12 games of the season.

- September 12 – Minnesota Twins pitcher Terry Felton takes the loss today, his thirteenth of the year against no wins. He'll not pitch for a decision again. Coupled with his 1980 record of 0-3, Felton's 0-16 major league career sets a futility record for the most losses without a big league win.
- October 1 – Through seven innings, the New York Mets' Terry Leach and the Philadelphia Phillies' John Denny have each only given up one hit. Denny is lifted in the ninth for a pinch hitter, however, Leach remains in the game through the tenth inning without giving up a second hit.

Robin Yount hit two home runs and Don Sutton outdueled Jim Palmer as the Milwaukee Brewers beat the Baltimore Orioles 11-2 to capture the AL East Title.
