Instead of running towards first, Cowens runs and attacks Farmer as revenge for being hit by a pitcher from Farmer the previous season, which broke Cowens jaw and cost him to miss 21 games as a member of the Kansas City Royals. An arrest warrant is issued for Cowens, which forces him to miss the rest of the series. Cowens is later suspended for a week by the AL.

• July 4
  • Houston Astros pitcher Nolan Ryan strikes out César Gerónimo of the Cincinnati Reds, to become the fourth major league pitcher ever to reach 3,000 career strikeouts. Gerónimo was also Bob Gibson's 3,000th career strikeout victim six years earlier. Despite the milestone, Ryan allows six runs in 4.1 innings and Houston loses, 8–1.
  • During the first-ever fireworks night hosted at Shea Stadium, Montreal Expos Rookie Bill Gullickson sailed a pitch over New York Mets first baseman Mike Jorgensen's head in the second game of a doubleheader. Jorgensen did not appreciate this as he had been the victim of one of the worst beanball injuries in baseball history the previous season with the Texas Rangers, and motioned toward Gullickson his disapproval. Mets catcher John Stearns, who was not even in the line-up for this game, charged out of the dugout and welcomed Gullickson to the majors by slamming him to the ground.
• July 6 – Philadelphia Phillies pitcher Steve Carlton becomes the major leagues' left-handed strikeout king, fanning seven Cardinals in an 8–3 Phillies win to bring his career total to 2,836. Mickey Lolich had held the record with 2,832.

• September 1 - Wade Boggs, playing for the Pawtucket Red Sox, loses the batting title on the last day of the season. Pawtucket is playing the Toledo Mud Hens, who force Boggs' last at-bat by walking the light hitting Ray Boyer. The Mud Hens, who led the game 6–0, allow Boyer to take bases at will. Boggs ends up grounding out to first to end the game, thus lowering his average. He finished the season .0007 points behind Dave Engle, who just happened to play for the Toledo Mud Hens.
  • Ed Farmer, who'd been assaulted during a game by Al Cowens earlier in the season, agrees to drop the charges. Before the game, both men brought the line-up cards to the home plate umpire, and later shook hands. The fans weren't as forgiving, as they booed Cowens every time he came to bat.

• September 19 - The Kansas City Royals rout the visiting Oakland A's, 13–3. George Brett gets two hits to keep his average above .400, marking the latest in a season that a player was hitting at or above .400 since Ted Williams in 1941.

It will not climb above .400 again, and he finishes the season with a .390 batting average, the closest any player had come to a .400 batting average since Ted Williams in 1941. Only Tony Gwynn will come closer than that before the 20th century ends.
  • A bronze plaque dedicated to Thurman Munson, who died unexpectedly the previous season in a plane crash, is unveiled in the team's monument park.

His great day would put him on the cover of Sports Illustrated the following week.
• September 30 - The New York Mets defeat the Pittsburgh Pirates 3–2 at Shea Stadium. Only 1,754 fans showed up, making it the smallest crowd to ever attend a game at Shea.

• October 1 - The Boston Red Sox fire manager Don Zimmer due to pressure from fans, who never forgave Zimmer for the late season collapse in 1978, who led to the one game play off in which Bucky Dent hit the game-winning home run for the Yankees over the green monster.
• October 4 – In a 17–1 rout of the Minnesota Twins, Willie Wilson of the Kansas City Royals becomes the first major league player ever to be credited with 700 at-bats in a single season, and ends the year with 705 at bats. He also sets the AL record for singles in a season with 184, eclipsing the mark Sam Rice set in 1925. Wilson also becomes only the second player in major league history to collect 100 hits from each side of the plate, matching the feat accomplished by Garry Templeton in 1979.
• October 4 – Philadelphia's Mike Schmidt hits a 2-run home run in the top of the 11th inning to give the Phillies a 6–4 win over the Montreal Expos at Olympic Stadium, clinching the National League East title.

• October 5 – On October 3, the Los Angeles Dodgers had been down three games to the Houston Astros to tie for the National League West Division title.

• October 9 – The Kansas City Royals win Game 2 of the 1980 ALCS 3–2, but the game is remembered for the top of the eighth inning. With Willie Randolph on first with two outs, Bob Watson lines a double to left. Yankee third base coach Mike Ferraro waves Randolph home, and the Royals gun him down at the plate. With a national television audience looking on, Yankee owner George Steinbrenner is shown in the stands on ABC game cameras shouting Ferraro's name at general manager Gene Michael. Steinbrenner ordered Yankee manager Dick Howser to fire Ferraro on the spot right after the game, but Howser refused.
• October 10 – In Game 3 of the 1980 ALCS, and with the New York Yankees leading 2–1, Kansas City Royals' George Brett delivered a three-run home run off Yankees' reliever Rich Gossage, and with it total revenge for the Royals, who won the pennant after being second best to the Yankees in the ALCS in 1976, 1977 and 1978. Kansas City won the pennant in, of all places, Yankee Stadium. After the game, Dick Howser resigns as Yankee manager over the events in Game 2 involving Mike Ferraro as described above.
• October 12 – The Philadelphia Phillies capture their first pennant since 1950 with a 10-inning, 8–7 win over the Houston Astros at the Astrodome, in the fifth and final game of the NL Championship Series.

• October 21 – The Philadelphia Phillies win the World Series, the first WS Championship in their 98-year history, by beating the Kansas City Royals, 4–1, in Game Six. Steve Carlton earns the win, though the most memorable moment may be Tug McGraw on the mound jumping for joy as he earns the save after loading the bases with no outs. Another equally memorable moment comes with one out in the bottom of the ninth when Frank White's pop-up is bobbled by Bob Boone, only to be tipped into the glove of Pete Rose. Philadelphia's Mike Schmidt is named MVP, hitting .381 with two home runs and seven RBI, while KC's Willie Wilson is the "goat", striking out a WS-record 12 times, including the final out of the Series with the bases loaded, and hitting only .154. Of the original 16 Major League franchises from 1901, the Phillies are the last to win their first World Series.
