Major league baseball final standings
- January 4 - David Clyde, who'd made his MLB debut as a promising prospect as a teenager, returns to the Texas Rangers as he and outfielder Jim Norris are sent to Texas by the Cleveland Indians in exchange for outfielder Gary Gray, pitcher Larry McCall, and minor league infielder Mike Bucci.

- January 24 – The New York Mets are sold to a group headed by Nelson Doubleday, Jr. and Fred Wilpon for an estimated $21.1 million. It was, at the time, the highest amount ever paid for an American professional sports franchise.
- February 12 – The Board of the Oakland Coliseum and the Oakland City Council both reject an attempt to buy out the remainder of the Oakland Athletics' lease to the stadium. This blocks an attempt to sell the team and a possible move to Denver.

- March 10 - The New York Yankees sign pitcher Jose Cano. The 18 year old Cano plays only one season in the Yankees farm system before he is released and spends the next two seasons out of baseball. However, his son Robinson Cano would later go on to have an all-star career with the Yankees.

- April 4 - Bud Harrelson is released by the Philadelphia Phillies.

- April 10 – Right Fielder Sixto Lezcano blasts a grand slam home run for the Milwaukee Brewers against the Boston Red Sox on Opening Day in the bottom of the 9th Inning to win the game, making him the first player to accomplish this feat in two straight years. Lezcano also hit a grand slam two years prior on Opening Day.
- After Texas Rangers starter Jon Matlack and New York Yankees starter Ron Guidry each pitch nine inning out shut out baseball, the Rangers win 1–0 in the 12th inning after Goose Gossage, in his only pitch of the game, throws a wild pitch with Richie Zisk at the plate. The wild pitch allows Ranger base runner (and former Yankee) Mickey Rivers to score from third.
- April 12 – Newly acquired Nolan Ryan makes his first National League start since 1971 for the Houston Astros and belts his first career home run, a three-run shot, in the fourth inning off Don Sutton of the Los Angeles Dodgers.

- April 22 – In a classic slugfest at Wrigley Field, the Chicago Cubs beat the St. Louis Cardinals, 16–12, on a two-out grand slam by Barry Foote off reliever Mark Littell in the bottom of the ninth inning.

- May 5 - Bill Madlock of the Pittsburgh Pirates is fined $5,000 and suspended for 15 days by NL president Chub Fenney. Madlock had shoved his glove in the face of umpire Gerry Crawford over a call in a game against the Montreal Expos four days earlier.
- May 7 - The Texas Rangers signed Bud Harrelson.
- May 11 - Pete Rose of the Philadelphia Phillies steals Second base, third base, and home plate in the Phillies 7–3 win over the Cincinnati Reds. Rose was the first player since Harvey Hendrick of the Pittsburgh Pirates in 1928 to pull off the stolen base cycle in one inning.

- June 3 - The June MLB player draft is held. Notable selections in the first round are Kelly Gruber, who'd go on to win a gold glove with the Toronto Blue Jays, who is drafted by the Cleveland Indians, the Montreal Expos take first baseman Terry Francona with the 22nd pick, and Darryl Strawberry by the New York Mets.
- June 4 - Jim Kaat, recently acquired by the St. Louis Cardinals from the New York Yankees, pitches 10 shut out innings against the New York Mets.

- June 16 - Tim Foli drove in three runs and struggling Bert Blyleven earned the 150th pitching victory of his career to lead the Pittsburgh Pirates to a 5-3 win over the Cincinnati Reds that was seen on ABC's Monday Night Baseball.
- June 17 - The Cleveland Indians are forced to close off a portion of the stadium due to rowdy fans pelting Brewers outfielders Gorman Thomas and Sixto Lezcano in a loss to the Brewers =the previous day. The portion of the stadium would not re-open until more security had been hired later that month.
- June 20 – California Angels shortstop Freddie Patek hits three home runs and collects seven RBIs in the Angels' 20–2 victory over the Boston Red Sox at Fenway Park.
- In a bizarre moment, Detroit Tigers Al Cowens hits a slow roller off White Sox pitcher Ed Farmer. 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.
- June 27 – At Candlestick Park, Jerry Reuss of the Los Angeles Dodgers no-hits the San Francisco Giants 8–0. A Bill Russell error on Jack Clark's first-inning ground ball is the only baserunner Reuss allows.
- July 1 - The New York Yankees release outfielder Paul Blair.

- 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.

A hurting Macko drives in a run with a double, is pinch-run for by Rick Reuschel, and never plays another game in the majors. Doctors examining Macko diagnose him with testicular cancer, and Macko would pass away in November 1981.
- August 11 - Reggie Jackson of the New York Yankees hits his 400th career home run of Britt Burns of the Chicago White Sox.
- August 12 - Nearly 50,000 fans cram into Tiger Stadium to watch former Tigers ace Mark Fidrych attempt a comeback. Boston won the game 5–2, and Fidrych's days in the majors begin to come to an end.
- August 17 - The Detroit Tigers hold a ceremony in which they retire the number 6 in honor of former star Al Kaline. Kaline becomes the first player in Tigers history to have his uniform number retired.

- 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.

- September 20 – George Brett goes 0-for-4 dropping his batting average below .400. 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.

- September 28 - Before an ABC National television audience, the Montreal Expos beat the Philadelphia Phillies, 8–3 to take a half-game lead in the National League East. Steve Rogers picked up his 16th win of the season while Gary Carter was the offensive hero for the Expos as he went 3-for-4 including 2 home runs. 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 oin which Bucky Dent hot 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 6 – After suffering through the three-game sweep of the Los Angeles Dodgers the last three days, Joe Niekro wins his twentieth game of the season to earn a win for the Houston Astros, 7–1, in a one-game playoff. It is the Astros' first 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. Each of the last four games was decided in extra innings. The Phillies, down by three runs to Nolan Ryan in the 8th inning, rally and go ahead on Garry Maddox's double in the 10th inning.
- 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.

Fingers never appears in a Cardinals uniform as he is traded again days later to the Milwaukee Brewers.
- December 9 – The Chicago Cubs send relief pitcher Bruce Sutter to their arch-rivals, the St. Louis Cardinals, in exchange for first baseman Leon Durham. Sutter will go on to save many more games for the Cardinals, while Durham's critical error in Game 5 of the 1984 NLCS will doom the Cubs.
