MLB statistical leaders
1 Modern single season strikeout record.

January

 * January 3 – A group of investors headed by 42-year-old Cleveland shipping and ship-building magnate George M. Steinbrenner III purchases the New York Yankees from CBS. The entire deal is valued at $10 million and includes parking lots near Yankee Stadium, but when CBS buys those properties back from the Yankees, the purchase price for the team falls to $8.8 million. By the time of Steinbrenner's death 37 years later, the Yankees are valued at over $1.6 billion.
 * January 11:
 * American League owners vote 8–4 to adopt the designated hitter position for a three-year trial period, after which (in 1975) it will be accorded permanent status. The DH, which future Commissioner of Baseball Bud Selig will call "the biggest rule change in the history of baseball to that point," is rejected by National League magnates and will not be adopted by the Senior Circuit until 2023.
 * The New York Yankees reveal that veteran MLB executive Gabe Paul has resigned as president and general manager of the Cleveland Indians and joined the 15-member ownership syndicate headed by George Steinbrenner that purchased the Bombers eight days earlier. Paul will occupy a senior executive post on the Yankee organization chart, but insists he will not displace incumbent president Michael Burke (also a minority owner) or general manager Lee MacPhail.
 * The Indians promote Paul's assistant, Phil Seghi, 63, to succeed his former boss as general manager.
 * January 18 – Free agent and longtime first baseman Orlando Cepeda, 35, signs with the Boston Red Sox, making the future Hall of Famer the first player signed to serve expressly as a designated hitter.
 * January 24 – Left-handed pitcher Warren Spahn, with 363 triumphs the winningest southpaw of all time, is elected to the Hall of Fame in his first try on the Baseball Writers' Association of America ballot, receiving 316 of 380 votes.
 * January 28 – The Hall of Fame Special Veterans Committee selects 19th-century pitcher Mickey Welch and Giants first baseman George Kelly, plus umpire Billy Evans, for enshrinement.

February

 * February 1 – Commissioner Bowie Kuhn announces the selection of Monte Irvin for the Hall of Fame by the Special Committee on the Negro Leagues.
 * February 27 – Chicago White Sox slugger and reigning American League Most Valuable Player Dick Allen signs a three-year contract for an estimated $250,000 per year, making him the highest-paid player in major league history.

March

 * March 5 – New York Yankees teammates and fellow left-handed pitchers Fritz Peterson and Mike Kekich arrive at spring training and announce that they have swapped their wives and families. Even the family dogs are traded.
 * March 8 – After only one season with the Cleveland Indians, former American League batting champion Alex Johnson is traded to the Texas Rangers for pitchers Vince Colbert and Rich Hinton. The Rangers become the sixth team Johnson has played for in his decade in the major leagues.
 * March 20 – In a special election held by the Baseball Writers' Association of America, the late Roberto Clemente receives 393 of 424 votes to earn entry into the Hall of Fame, less than three months after his death in a plane crash during a humanitarian mission to earthquake-ravaged Nicaragua. The Hall's board of directors had earlier waived the five-year-wait rule for Clemente.
 * March 24 – The Cleveland Indians trade catcher Ray Fosse and infielder Jack Heidemann to the Oakland Athletics for catcher Dave Duncan and outfielder George Hendrick.
 * March 26 – Denny McLain, who won 31 games for the Detroit Tigers in 1968, becoming the last MLB pitcher to win 30 games, is released by the Atlanta Braves. His career tarnished by his 1970 suspension for association with known gamblers, McLain never pitches in the major leagues again.
 * March 29 – Orange baseballs, the brainchild of Oakland Athletics owner Charlie Finley, are used in the Athletics' 11–5 exhibition loss to the Cleveland Indians.

April

 * April 6:
 * At Three Rivers Stadium, 51,695 fans watch as the jersey #21 of the late Roberto Clemente is retired. The Pittsburgh Pirates then beat the St. Louis Cardinals 7–5, with a ninth-inning rally.
 * At Fenway Park, Ron Blomberg of the New York Yankees becomes the first designated hitter in major league history. He is walked by Boston Red Sox pitcher Luis Tiant in his first plate appearance. Boston wins 15–5, however, powered by two home runs and six runs batted in from sophomore catcher Carlton Fisk.
 * At Oakland–Alameda County Coliseum, Tony Oliva of the Minnesota Twins becomes the first designated hitter to homer, with a first-inning shot off Catfish Hunter.
 * April 10 – The Kansas City Royals open their new park, Royals Stadium, with a 12–1 rout of the Texas Rangers. The game is attended by 39,464 fans braving 39-degree weather.
 * April 17:
 * Philadelphia Phillies pitcher Dick Ruthven, the first player selected in the secondary phase of the January 1973 amateur draft out of Fresno State, makes his major league debut without playing in the minors. He starts against the Montreal Expos, allowing four runs in less than two innings, but does not figure in the decision as the Phillies win 9–6.
 * The San Francisco Giants sell the contract of former starting third baseman Jim Ray Hart, 31, to the New York Yankees. Hart will assume the role of the Bombers' primary designated hitter with Ron Blomberg gaining playing time at first base.
 * April 27 – In 50-degree weather, Kansas City Royals rookie Steve Busby no-hits the host Detroit Tigers 3–0. For the Royals, who began play in 1969, it's the first no-hitter in franchise history, and the first in Tiger Stadium since Virgil Trucks' in 1952. With the designated hitter rule in effect, Busby becomes the first pitcher of a no-hitter to not come to bat.
 * April 28 – The San Francisco Giants' Jim Willoughby tosses a four-hit, complete game shutout and Bobby Bonds provides the only run he needs with a first-inning homer off Reggie Cleveland, as the Giants defeat the St. Louis Cardinals 1–0 at Busch Memorial Stadium. The loss gives the Cardinals an abysmal 2–15 record for 1973—but they will battle back to reach .500 in late June and take the National League East's divisional lead July 22, before ultimately placing second by the end of the campaign.
 * April 29 – Michael Burke, president of the New York Yankees since 1966, resigns amid rumors of disagreements with general partner George Steinbrenner. Burke remains a limited partner in the Yanks' ownership group, which took control of the club on January 3.
 * April 30 – All 24 teams are off. It would be the last time all teams would receive a day off during the regular season (except for All-Star breaks and labor stoppages) until June 29, 1998.

May

 * May 4 – José Pagán's sacrifice fly in the bottom of the 20th inning gives the Philadelphia Phillies a 5–4 victory over the Atlanta Braves. Both managers are ejected during the marathon contest: the Phillies' Danny Ozark during the 17th inning, and the Braves' Eddie Mathews in the 20th, when he argues the decisive "safe" call at home plate.
 * May 8:
 * For the second time in his career, Willie Stargell of the Pittsburgh Pirates hits a home run out of Dodger Stadium. His blast off Andy Messersmith hits the right field pavilion roof 470 feet away. His first home run, a 506-foot shot, came off Alan Foster on August 5, 1969. The Los Angeles Dodgers win, 7–4.
 * In a 9–7 losing effort against the San Francisco Giants, St. Louis Cardinals ace Bob Gibson makes his 242nd consecutive start. It is a new 20th-century record, passing that of Red Ruffing, who never pitched in relief the last ten years of his career.
 * Whitey Lockman, manager of the Chicago Cubs, is ejected by Shag Crawford in the 11th inning of a road game against the San Diego Padres. Coach Ernie Banks takes over, unofficially becoming the first black manager in major league baseball. With Banks at the helm, the Cubs push across the winning run in the 12th on a pinch-hit double by Joe Pepitone.
 * May 9 – Johnny Bench of the Cincinnati Reds belts three home runs off fellow future Hall-of-Famer Steve Carlton for the second time in his career, in a 9–7 victory over the Philadelphia Phillies. Bench knocks in seven runs.
 * May 11 – Manager Leo Durocher returns to the Houston Astros' dugout after being sidelined since April 20 by diverticulitis. In his absence, the Astros have gone 14–3 under coach Preston Gómez and climbed to second place in the National League West.
 * May 15:
 * Nolan Ryan of the California Angels pitches the first of his seven career no-hitters, defeating the Kansas City Royals, 3–0 at Royals Stadium. Ryan fans 12 and issues three bases on balls.
 * At County Stadium, Dave May's 17th-inning walk-off home run enables his Milwaukee Brewers to edge the Cleveland Indians, 2–1. The 15–15 Brewers are the only team in the American League East with a .500-or-above record
 * May 19 – The Atlanta Braves trade Andre Thornton to the Chicago Cubs in exchange for Joe Pepitone.
 * May 20 – The 12–23 Texas Rangers make a five-player deal with a division rival, sending pitcher Rich Hand, catcher Rick Stelmaszek and first baseman Mike Epstein to the 21–14 California Angels for pitcher Lloyd Allen and first baseman Jim Spencer.
 * May 24:
 * Willie Davis of the Los Angeles Dodgers gets six hits, all singles, in a 19-inning, 7–3 loss to the New York Mets at Dodger Stadium. The record will still stand, as of 2017, for most hits in a game by a Dodger.
 * Bert Blyleven of the Minnesota Twins one-hits the Kansas City Royals, 2–0 at Metropolitan Stadium. The lone Kansas City safety is a fifth-inning bunt single by Ed Kirkpatrick.
 * May 27 – Beset by financial troubles, C. Arnholt Smith, majority owner of the five-year-old San Diego Padres, announces he is selling the team to Joseph Danzansky and two partners for $12 million. Danzansky's group plans to move the franchise to Washington, D.C. The city attorney for San Diego reacts by filing an $84 million suit for damages against Smith, Danzansky and the National League seeking payment for the team's stadium lease, which has 15 years to run, and other anticipated lost revenues.
 * May 28 – Dick Allen blasts a three-run home in the home half of the 22nd inning to give the Chicago White Sox a 6–3 victory over the Cleveland Indians in a game that was suspended May 26 in the 17th inning. Later on this day, in the regularly scheduled game, knuckleball artist Wilbur Wood improves to 13–3 by tossing a four-hit shutout. Their 4–0 triumph gives the 26–14 ChiSox a 3½-game lead in the American League West.
 * May 31:
 * At Wrigley Field, the Chicago Cubs score ten first-inning runs against the Houston Astros and cruise to a 16–8 win.
 * Ken Holtzman and Rollie Fingers combine for a one-hitter in a 6–0 Oakland Athletics triumph over the New York Yankees in The Bronx. The Yanks' Matty Alou touches Holtzman for a seventh-inning single for his team's only safety.

June

 * June 5 – Left-handed hurler David Clyde, a Houston high-school phenom, is chosen by his home-state Texas Rangers as the #1 selection in the June 1973 Major League Baseball draft. After the Philadelphia Phillies take catcher John Stearns with the second pick and the Milwaukee Brewers use the third overall pick to select shortstop Robin Yount, outfielder Dave Winfield of the University of Minnesota is selected fourth by the San Diego Padres. Both Clyde and Winfield will go straight to the major leagues; Yount will need only one year of minor-league seasoning, but he and Winfield will end up the Baseball Hall of Fame.
 * June 7 – The 28–25 New York Yankees, enmeshed in another tight American League East divisional race, strengthen their mound staff by acquiring Pat Dobson from the Atlanta Braves and "Sudden" Sam McDowell from the San Francisco Giants. Dobson goes 9–8 for the 1973 Yankees, then wins 19 games in 1974 with a 3.07 ERA and 12 complete games. McDowell is less effective, posting a 6–14 (4.20 ERA) record over the same span.
 * June 9 – After the Old Timers' Game at Shea Stadium, Willie Mays puts on his own show with a home run and a circus catch, and the New York Mets top the Los Angeles Dodgers 4–2. For Mays, older than a half dozen of the old Mets, it is the 655th homer of his career. Rusty Staub drives in two runs to back Jon Matlack. In the Old Timers' Game, the Brooklyn Dodgers/New York Yankees team loses to the Mets 1–0 in two innings.
 * June 12:
 * The Cincinnati Reds add a 5 ft left-handed pitcher who will be a big contributor to their division, pennant and World Series winners from this season through 1979, obtaining Fred Norman from the San Diego Padres for pitcher Mike Johnson, outfielder Gene Locklear and cash.
 * The New York Yankees trade left-hander Mike Kekich to the Cleveland Indians for righty Lowell Palmer. Fritz Peterson, the Yankees' southpaw with whom Kekich exchanged wives, children, and dogs (see March 5, 1973), remains in The Bronx.
 * June 13 – At Riverfront Stadium, St. Louis Cardinals pitcher Rick Wise loses a no-hitter when the Cincinnati Reds' Joe Morgan singles with one out in the ninth inning. It will be the only hit Wise allows in an 8–0 shutout win. Wise, who no-hit the Reds at Riverfront in 1971, was bidding to join Addie Joss as the only pitchers to throw two no–hitters against the same team.
 * June 19:
 * In the Los Angeles Dodgers' 4–0 victory over the Cincinnati Reds, Pete Rose (single) and Willie Davis (HR) each collect their 2,000th career hit.
 * Dave Winfield debuts in the San Diego Padres' 7–3 loss to the Houston Astros. Winfield—who was also drafted by the Minnesota Vikings of the NFL and basketball's Atlanta Hawks (NBA) and Utah Stars (ABA)—goes one for four in his debut, and he will never spend a day in the minor leagues.  After a 22-year career, he is voted into the Baseball Hall of Fame in 2001.
 * June 20:
 * Cy Acosta of the Chicago White Sox becomes the first American League pitcher to bat since the DH rule went into effect earlier this season. Acosta strikes out in the eighth inning, but is credited with an 8–3 victory over the California Angels.
 * Bobby Bonds leads off with a home run, but the San Francisco Giants lose 7–5 to Cincinnati. It is Bonds' 22nd leadoff home run, breaking Lou Brock's National League record.
 * June 23 – Pitcher Ken Brett of the Philadelphia Phillies tops the Montreal Expos 7–2, and hits a home run for his fourth consecutive game, setting a major league record for a hurler. Previously, Brett hit home runs on June 9, 13, and 18. One of the best-hitting pitchers of the 1970s, Brett will slug ten home runs and bat .262 lifetime in 347 career at bats.
 * June 27 – Before a packed house of 35,698 at Arlington Stadium, 18-year-old southpaw starting pitcher David Clyde, the first player selected in the 1973 Major League Baseball Draft, makes his professional debut for the Texas Rangers by getting credit for a 4–3 win over the Minnesota Twins. The recent graduate of Houston's Westchester High School goes five innings and allows only one hit and two runs, striking out seven but walking eight hitters. He'll enjoy four more impressive outings in 1973, but the combination of being rushed to the big leagues and a shoulder injury will contribute to a mediocre MLB career: 18 wins, 33 losses, and a 4.63 career ERA in 84 games and 416 $1⁄3$ innings pitched.
 * June 28:
 * Willie Stargell hits his 300th career home run, helping the Pittsburgh Pirates defeat the St. Louis Cardinals 6–0.
 * Bob Bailey's RBI single delivers an 18-inning, 5–4 victory to the Montreal Expos over the Chicago Cubs in the completion of a game suspended due to darkness the previous evening at Wrigley Field, the only MLB stadium without arc lights. The contest began on June 27 as the second game of a doubleheader and had to be suspended in the 13th frame before it's resumed today. Then, in the regularly schedule game, the Cubs win 4–2 behind Milt Pappas.

July

 * July 1 – Luis Aparicio of the Boston Red Sox steals the 500th base of his career in a 9–5 loss to the Milwaukee Brewers. It is the highest total in the American League since Eddie Collins (741 career steals) retired in 1930.
 * July 2 – The Detroit Tigers sign undrafted free agent Ron LeFlore. An outfielder and 25-year-old Detroit native, LeFlore is also an ex-convict who served over three years in Jackson State Prison for armed robbery and first played baseball seriously during his time as an inmate. He goes on to a nine-year career for the Tigers, Montreal Expos and Chicago White Sox in which he becomes the first player to lead each of the major leagues in stolen bases, and is selected to the 1976 American League All-Star team. He never returns to prison.
 * July 3 – At Cleveland Stadium, brothers and starting pitchers Gaylord Perry (Indians) and Jim Perry (Tigers) hurl against each other for the only time in their careers. Neither finishes the game, but Gaylord is charged with the 5–4 loss. Two Norm Cash home runs help the Tigers.
 * July 4:
 * The Minnesota Twins bring their first-round June draft pick, pitcher Eddie Bane, straight to the major leagues, in an attempt to boost interest and attendance (the brainchild of owner Calvin Griffith). Bane brings a 40–4 record with him from Arizona State University, and goes seven innings in his debut, a no-decision start. A crowd of 45,890 is on hand at Metropolitan Stadium.
 * The division leaders at the MLB season's traditional halfway point are the 48–34 Chicago Cubs in the National League East, 5½ games ahead of the St. Louis Cardinals; the 51–31 Los Angeles Dodgers in the NL West, 3½ lengths up on the San Francisco Giants; the 46–36 New York Yankees in the AL East, two games in front of the Baltimore Orioles; and the 45–37 Oakland Athletics, only one game ahead of the Minnesota Twins in the AL West. Only Oakland will make the postseason. Their eventual World Series foes, the New York Mets, are last in the NL East with 33–43 mark, 12 games behind the Cubs.
 * July 9 – In a record-setting walkathon between the Cincinnati Reds and Montreal Expos, 25 bases on balls are handed out as Montreal strolls to an 11–6 win. Well off the American League's two-team mark of 30, this tops the National League record of 23, last reached on July 7, 1911. Six Montreal pitchers walk 16, one short of the record for an NL team, while two Reds pitchers walk nine. Hal King pinch hits a grand slam for the Reds in the 6th inning, his second pinch homer in nine days.
 * July 11:
 * Jim Northrup, batting leadoff for the Detroit Tigers, drives in eight runs in a 14–2 win over Texas.
 * In San Diego, the Pittsburgh Pirates drub the Padres 10–2. Willie Stargell contributes the 302nd home run of his career to pass Ralph Kiner as the all-time Pirate home run leader.
 * The New York Mets sell the contract of third baseman Jim Fregosi to the Texas Rangers. The Mets had obtained Fregosi, a six-time All-Star, from the California Angels in December 1971 for Nolan Ryan and three other players. This transaction closes the book on his Mets career: 146 games played, 108 hits, five home runs, 43 runs batted in, and a .233 batting average.
 * July 15:
 * Willie McCovey hits his 400th career home run, helping the San Francisco Giants beat the Pittsburgh Pirates, 12–0.
 * Nolan Ryan pitches his second no-hitter of the season (and the second of seven for his career). He strikes out seventeen Detroit Tigers as the visiting California Angels win, 6–0.
 * July 20 – Wilbur Wood of the Chicago White Sox starts and loses both games of a doubleheader against the New York Yankees, 12–2 and 7–0. After starting the season 13–3, Wood's won–lost mark is now 18–14.
 * July 21 – Hank Aaron of the Atlanta Braves hits a Ken Brett fastball into the left-center field stands of Atlanta–Fulton County Stadium during an 8–4 loss to the Philadelphia Phillies. It is career home run #700 for Aaron, only the second player to reach that milestone. Only Babe Ruth, with 714, has more.
 * July 24 – The National League wins the All-Star Game at Kansas City, 7–1. A record 54 players are used, including Willie Mays, who strikes out in his final All-Star appearance, and Catfish Hunter, who sustains a fractured thumb that will sideline him for four weeks. Hunter has a 15–3 record at the time. Johnny Bench, Bobby Bonds and Willie Davis all hit home runs for the NL and Bonds edges out Davis for the game MVP by one vote.
 * July 26 – Pat Dobson of the New York Yankees throws 11 shutout innings against the Milwaukee Brewers until he's relieved by Sparky Lyle in the top of the 12th. In the bottom of the frame, Thurman Munson's RBI single gives the first-place Yankees (and Lyle) a 1–0 victory.
 * July 30 – At the Oakland–Alameda County Coliseum, Jim Bibby of the Texas Rangers no-hits the Oakland Athletics 6–0. The no-hitter is the first in the history of the 13-year-old Washington Senators/Texas Rangers franchise.
 * July 31 – The Athletics sign free-agent veteran second baseman Mike Andrews, released 15 days earlier by the Chicago White Sox. They also acquire veteran outfielders Jesús Alou and Vic Davalillo. All will play significant roles in the postseason to come.

August

 * August 1 – With the score tied at 2–2 in the top of the ninth at Fenway Park, in an incident that typifies both the Yankees–Red Sox rivalry and the feud between the two catchers involved, Thurman Munson of the New York Yankees barrels into Carlton Fisk of the Boston Red Sox while trying to score on Gene Michael's missed squeeze attempt. The incident triggers a 10-minute bench-clearing brawl in which both catchers are ejected. The Red Sox win 3–2 in the bottom of the ninth, with Mario Guerrero's two-out single scoring Bob Montgomery (who had replaced the ejected Fisk) for the winning run.
 * August 2 – Future Hall-of-Famer George Brett, in his third pro season, makes his MLB debut by going one-for-four for the Kansas City Royals against the Chicago White Sox and Stan Bahnsen at Comiskey Park. The first of his 3,154 career hits is a fourth-inning single to left field.
 * August 5 – Atlanta Braves knuckleballer Phil Niekro no-hits the San Diego Padres 9–0. He walks three and strikes out four in recording the first no-hitter by the franchise since it moved to Atlanta.
 * August 6 – An exhibition game between the Milwaukee Brewers and the Atlanta Braves at Milwaukee draws 33,337. The Brewers win, 7–5, in the fourth and last exhibition between the two teams. But the big thrill is provided by Hank Aaron, a Milwaukee Brave from 1954 until the franchise moved after the 1965 season, who hits a home run.
 * August 7 – Two days after Phil Niekro's no-hitter, the Braves purchase Joe Niekro, Phil's pitching brother, from the Detroit Tigers.
 * August 11 – Chicago White Sox rookie Brian Downing cracks his first major league hit, a home run off Detroit's Mickey Lolich. Downing's debut dinger is a first in the majors since at least 1945 – an inside-the-park homer. It'll be matched in two years by the Giants Johnnie LeMaster, who will do it in his first at-bat.
 * August 15:
 * At Three Rivers Stadium, Cincinnati Reds ace Jack Billingham beats the host Pittsburgh Pirates 1–0, notching his seventh shutout of the season. This ties the club record set by Hod Eller back in 1919.
 * Future Hall-of-Fame left-hander Jim Kaat is claimed off waivers by the Chicago White Sox, ending his 15-season-long tenure with the Washington Senators/Minnesota Twins franchise, for whom he won 190 games.
 * August 17 – The New York Mets' Willie Mays hits the 660th (and last) home run of his career off Don Gullett of Cincinnati, but the Reds win 2–1 in 10 innings at Shea Stadium, after pinch hitter Hal King hits a walk-off home run, his third pinch homer of the year.
 * August 21 – Against the Indians at Cleveland Stadium, Stan Bahnsen of the Chicago White Sox has a no-hitter broken up with two out in the ninth on a single by ex-teammate Walt Williams. The hit is the only one Bahnsen allows as the White Sox defeat the Indians 4-0.
 * August 30 – Detroit Tigers manager Billy Martin is fired with one year left on a reported $65,000 annual contract. Detroit, defending American League East champion, is 71–63 in 1973, in third place and 7½ games behind the front-running Baltimore Orioles. Third-base coach Joe Schultz is named acting manager and he will serve out the regular season.

September

 * September 1 – As the final full month of the 1973 season begins, the Baltimore Orioles and defending World Series champion Oakland Athletics sit atop their American League divisions by margins of six and 5½ games, respectively. In the National League West, the Los Angeles Dodgers hold a three-game advantage over the Cincinnati Reds with each team having 26 contests to play. However, an unusual divisional race is unfolding in the National League East. All six teams, even the last-place Philadelphia Phillies, are tightly bunched and only six games separate them. The first-place St. Louis Cardinals are the lone team over .500, at 68–66, and they hold a one-game lead over runner-up Pittsburgh (65–65).
 * September 3 – The San Francisco Giants overcome a 7–1 deficit to beat the Dodgers 11–8 at Candlestick Park during a nationally televised Monday Night Baseball game on NBC. Bobby Bonds hits a walk-off grand slam into the right field seats to win the game for the Giants.
 * September 4 – In the midst of a scorching, month-long streak that sees them win 22 of 28 games between August 25 and September 25, the Cincinnati Reds plate five runs in the top of the tenth inning to defeat Houston at the Astrodome, 12–7. The victory enables the Reds to move into undisputed possession of first place in the NL West, one game ahead of the Los Angeles Dodgers.
 * September 6:
 * After dropping three of four games to the St. Louis Cardinals at their home field, the 67–69 Pittsburgh Pirates unexpectedly fire second-year manager Bill Virdon, and ask former pilot Danny Murtaugh to return to uniform and take over for the rest of the season and 1974. Murtaugh, 55, will begin his fourth and final term (since August 1957) as the Pirates' manager; he previously led them to World Series championships in 1960 and 1971. He had moved into the Pittsburgh front office in November 1971 because of ongoing health issues.
 * Brothers Felipe Alou and Matty Alou are claimed on waivers from the New York Yankees by NL East divisional contenders. Felipe's contract is sold to the Montreal Expos and Matty goes to the St. Louis Cardinals.
 * September 7 – Future Hall of Fame pilot Whitey Herzog is fired from his first MLB managerial assignment by the Texas Rangers with the club in the AL West cellar at 47–91. Del Wilber serves as interim manager for one game before owner Bob Short names Billy Martin, fired by the Tigers only days earlier, as Herzog's permanent replacement.
 * September 17 – The five-year-old Montreal Expos achieve something they have never done before—reaching first place in the NL East this late in a season. It happens after the opening game of a doubleheader, when they beat the St. Louis Cardinals 5–4 on a two-run, ninth-inning rally. But their time on the throne is short-lived: a 12-inning loss in game two of the twin-bill drops the Expos into the division's runner-up position.
 * September 19 – The Pittsburgh Pirates lose the first game of a crucial three-game series at Shea Stadium for first place 7–3 to the New York Mets when Cleon Jones registers just the second two home run performance of his 11-season career (the first time was on April 6, in the season opener against the Philadelphia Phillies).
 * September 20 – At Shea Stadium, in the top of the 13th inning, with Richie Zisk on first, the Pittsburgh Pirates' Dave Augustine belts what appears to be a home run over the left field wall. New York Mets left fielder Cleon Jones turns to play the ball off the wall and the ball hits the top of the wall and bounces right into Jones' glove on the fly. Jones turns and throws to relay man Wayne Garrett, who throws home to catcher Ron Hodges to nail Zisk at the plate. Following the "Ball on the Wall" play, the Mets win the game in the bottom half of the inning to move within half a game of the first place Pirates. The Mets are now 14–6 during the month of September.
 * September 22:
 * At Milwaukee County Stadium, the Baltimore Orioles' Doyle Alexander scatters seven hits and defeats the Brewers 7–1, enabling the Os to clinch their fourth American League East division title in five years.
 * The New York Mets gain sole possession of first place in the NL East, as Jon Matlack defeats the visiting St. Louis Cardinals 2–0. Wayne Garrett's two-run homer in the third inning provides all the run support that Matlack needs.
 * September 23 – With Vida Blue winning his 20th game, the Oakland Athletics capture their third consecutive AL West title with a 10–5 victory over the Chicago White Sox at Comiskey Park. The Sox' Wilbur Wood, already a 24-game-winner, sustains his 20th defeat of 1973, making him the first hurler since Baseball Hall of Famer Walter Johnson (25–20 in 1916) to both win and lose 20 or more games in the same season.
 * September 24 – The defending National League champion Cincinnati Reds clinch their third NL West crown in four seasons with a 2–1 victory over the San Diego Padres behind journeyman right-hander Dick Baney at Riverfront Stadium.
 * September 27 – Capping a memorable season, Nolan Ryan strikes out 16 Minnesota Twins en route to a 5–4, 11-inning win for the California Angels. Rich Reese is Ryan's final strikeout, his 383rd of the season, which breaks Sandy Koufax's season record.
 * September 29 – In his penultimate game of 1973, 39-year-old Hank Aaron hammers his 713th career regular-season home run in a 7–0 victory over the Houston Astros at Atlanta–Fulton County Stadium. The victim is southpaw Jerry Reuss. The homer is Aaron's 40th of the season, and leaves him one shy of Babe Ruth's all-time record, which he will continue to pursue in 1974.
 * September 30:
 * At the close of the last day of the regular season, the National League East race still isn't resolved. Three teams remain mathematically eligible, even though only one has an above-.500 record. The "survivors" are the New York Mets (81–79), St. Louis Cardinals (81–81) and Pittsburgh Pirates (80–81). To settle matters, games that had been rained out during 1973 must be played on Monday, October 1: the Mets are scheduled for a doubleheader at Wrigley Field to make up games washed out Friday and Saturday, and the Pirates must make up a July 21 rainout against the San Diego Padres at Three Rivers Stadium. An unprecedented three-way tie looms if the Mets are swept in their doubleheader and the Pirates defeat San Diego.
 * The New York Yankees play their final game in the original Yankee Stadium, losing to the Detroit Tigers 8–5. "The House That Ruth Built" will remain closed, and the Yanks will share Shea Stadium with the Mets, until 1976 while The Bronx' landmark undergoes major renovations. After 11 years at the helm (944–806, .539, three pennants, two World Series titles), Ralph Houk resigns as the Bombers' manager. His resignation also ends Houk's 35-year career in the Yankee organization.
 * The second-place Boston Red Sox relieve fourth-year manager Eddie Kasko (345–295, .539) of his duties. They will immediately name former MLB catcher Darrell Johnson their skipper for 1974. Johnson has just directed the Triple-A Pawtucket Red Sox to the Governors' Cup and Junior World Series titles.

October

 * October 1:
 * With the National League West champion Cincinnati Reds and potential NL East co-leader St. Louis Cardinals awaiting the outcome, the East Division race is decided by two make-up, regular-season contests. The San Diego Padres, losers of 102 games and last-place finishers in the West, fly to Pittsburgh, where they eliminate the Pirates, 4–3. And in Chicago, the New York Mets ride the pitching of Tom Seaver and Tug McGraw to a 6–4 victory over the Cubs to sew up the NL East pennant at 82–79. With the division finally decided, a potential second game of a Mets–Cubs doubleheader is cancelled. The Mets, in fifth place on September 1, go 19–8 over the next 30 days to grab the division flag.
 * The controversial—but ultimately Hall-of-Fame-worthy—managerial career of Leo Durocher comes to an end when he resigns from the Houston Astros. Now 68, the hyper-competitive and abrasive "Leo the Lip" began that career as the 33-year-old shortstop–manager of the 1939 Brooklyn Dodgers, who he immediately led into the first division and then, two years later, to the 1941 National League pennant. Moving to the New York Giants in July 1948, he oversaw a turnaround on the field, then coaxed them to an NL pennant in 1951 and the 1954 World Series championship. However, Durocher's career was tarnished when he was suspended by Commissioner of Baseball Happy Chandler for the entire 1947 season for "conduct detrimental to baseball" and, after quitting the Giants in 1955, he was rejected by at least three MLB teams for open managerial jobs. Late in his career, he skippered the 1966–1972 Chicago Cubs and 1972–1973 Astros. His final managers' ledger is 2,008–1,709 (.540), three NL pennants and one World Series title over 24 seasons. Preston Gómez, a Houston coach who went 16–5 as the Astros' acting manager during Durocher's two absences for ill health in 1973, is immediately named Leo's successor.
 * October 8 – In Game 3 of the 1973 National League Championship Series, the New York Mets' Rusty Staub homers in the first and second innings as the Mets crush the Cincinnati Reds 9–2 at New York's Shea Stadium to take a two-games-to-one series lead. The game features a fifth-inning, bench-clearing brawl triggered by Pete Rose's hard slide into Mets' shortstop Bud Harrelson as he attempts to break up a double play. Punches are thrown but neither man is ejected. Rose and Harrelson will later be teammates on the 1979 Philadelphia Phillies.
 * October 10 – As in 1969, when no one thought the New York Mets would win the National League pennant, they "amazingly" repeat history as Tom Seaver pitches them into the 1973 World Series with a 7–2 victory over the favored Cincinnati Reds in Game 5 of the 1973 National League Championship Series. New York has 13 hits in the contest.
 * October 11:
 * Catfish Hunter tosses a five-hitter and Joe Rudi, Vic Davalillo and Jesús Alou deliver RBIs, enabling the Oakland Athletics to down the Baltimore Orioles, 3–0, in the decisive Game 5 of the 1973 American League Championship Series. Oakland wins its second consecutive American League championship and will face the Mets in the World Series.
 * The Detroit Tigers sign former New York Yankees' skipper Ralph Houk, 54, to a three-year contract as their manager. The Houk-to-Detroit rumor has been circulating since "The Major" quit the Bombers on September 29. On October 25, the Yankees will ask outgoing American League president Joe Cronin to investigate alleged tampering with Houk while he was under contract.
 * October 13 – The Oakland Athletics score two unearned runs in the third inning of Game 1 of the 1973 World Series when the usually sure-handed Félix Millán allows a ground ball to go through his legs. They are the only runs New York Mets starter Jon Matlack allows, but they're enough to give Oakland the 2–1 victory.
 * October 14 – In one of the more bizarre incidents in World Series history, the Mets defeat the Athletics 10–7 in extra innings in Game 2 by scoring four runs in the top of the 12th; three of those runs result from two errors by Oakland second baseman Mike Andrews. After the game, Athletics owner Charlie O. Finley forces Andrews to sign a false affidavit stating he was disabled, which would render him ineligible for the remainder of the series. Oakland manager Dick Williams rallies to Andrews' defense and Commissioner of Baseball Bowie Kuhn nullifies the affidavit. Nevertheless, Finley orders Williams to bench Andrews. In defiance, Williams sends Andrews to the plate as a pinch hitter in Game 4 in New York three nights later, and the Mets' home crowd gives him a standing ovation.
 * October 18 – The Philadelphia Phillies acquire starting second baseman Dave Cash, 25, a future three-time All-Star, from the Pittsburgh Pirates for lefthanded pitcher Ken Brett.
 * October 21:
 * Bert Campaneris and Reggie Jackson hit two-run home runs in the third inning as the Oakland Athletics defeat the New York Mets, 5–2, in Game 7 of the World Series for their second straight world championship. Jackson is selected the Series MVP.
 * Immediately after the game, Oakland manager Dick Williams announces his resignation for "personal reasons." Rumors immediately surface that he will join George Steinbrenner's New York Yankees, who still seek a manager after Ralph Houk's September 29 resignation. His consecutive World Series championships in 1972–1973 will be a deciding factor that enables Williams to claim a berth in the Baseball Hall of Fame in 2008.
 * October 22 – The California Angels and Milwaukee Brewers pull off a nine-player transaction in which the Angels send southpaw pitchers Steve Barber and Clyde Wright, catcher Art Kusnyer, outfielder Ken Berry and cash to the Brewers for pitchers Skip Lockwood and Gary Ryerson, catcher Ellie Rodríguez, and outfielders Ollie Brown and Joe Lahoud.
 * October 23:
 * Athletics owner Charlie Finley reveals that he will not release manager Dick Williams from his contract unless he receives adequate compensation from the team that signs him. Williams had resigned following the World Series victory two days earlier.
 * The Detroit Tigers begin their rebuild by trading 34-year-old stalwart second baseman Dick McAuliffe to the Boston Red Sox for young reserve outfielder Ben Oglivie.
 * October 24 – The Red Sox continue what will be an extremely active off-season for them by exchanging right-handed pitchers with the Kansas City Royals, sending Marty Pattin to the Royals for Dick Drago.
 * October 25:
 * The Chicago Cubs trade future Hall-of-Fame pitcher, 30-year-old Ferguson Jenkins, at this point a six-time 20-game winner, three-time All-Star and the 1971 National League Cy Young Award recipient, to the American League's Texas Rangers for two young infielders, Bill Madlock, 22, and Vic Harris, 23.
 * Another future Cooperstown enshrinee changes address when the San Francisco Giants send 35-year-old slugging first baseman Willie McCovey, a 6x All-Star, 1969 NL Most Valuable Player and 3x NL home run champ, to the San Diego Padres, along with outfielder Bernie Williams, for left-hander Mike Caldwell.
 * October 26 – The Boston Red Sox pull off their third significant trade in four days, dealing two-time All-Star outfielder Reggie Smith and relief pitcher Ken Tatum to the St. Louis Cardinals for starting pitcher Rick Wise and outfielder Bernie Carbo.
 * October 31 – The Pittsburgh Pirates acquire southpaw starting pitcher Jerry Reuss from the Houston Astros for young catcher Milt May.

November

 * November 1:
 * The New York Yankees revamp their front office after former general manager Lee MacPhail becomes president-elect of the American League. Limited partner Gabe Paul, 63, a longtime baseball executive, becomes club president and de facto GM. Paul recruits Tal Smith, 40, to serve directly under him as executive vice president of baseball operations. Smith is a former GM of the Houston Astros and began his MLB career working under Paul with the Cincinnati Reds.
 * The Oakland Athletics release Mike Andrews, ending the second baseman's eight-year MLB career.
 * November 3 – Two trades will see four relief pitchers change teams: the Houston Astros send Cecil Upshaw, 31, to the Cleveland Indians for Jerry Johnson, 29; and the Chicago Cubs deal Bob Locker, 35, to the Oakland Athletics for Horacio Piña, 28.
 * November 7:
 * The Chicago Cubs break up their longtime double-play combo by sending veteran second baseman Glenn Beckert, along with infielder Bobby Fenwick, to the San Diego Padres for outfielder Jerry Morales. Beckert, 33, is a four-time National League All-Star and 1968 Gold Glove Award-winner who has teamed up with shortstop Don Kessinger for nine MLB seasons.
 * The Philadelphia Phillies and Milwaukee Brewers swap relief pitchers, with the Phils acquiring veteran Frank Linzy, 33, for Bill Wilson, 31.
 * November 9 – Still poised for a sale and transfer to Washington, D.C., the Padres continue to acquire veteran position players, trading pitcher Clay Kirby to the Cincinnati Reds for centerfielder Bobby Tolan and left-handed relief pitcher Dave Tomlin.
 * November 27 – San Francisco Giants left fielder Gary Matthews, who hit .300 with 12 home runs and 58 RBI in 145 games, outpolls eight others receiving 11 of 24 nominations for the National League Rookie of the Year Award. The runners-up are Steve Rogers (P), Bob Boone (C), Dan Driessen (3B), Elías Sosa (P), Ron Cey (3B), Johnny Grubb (CF), Davey Lopes (2B) and Richie Zisk (RF).
 * November 28 – Al Bumbry, centerfielder of the Baltimore Orioles, wins the 1973 American League Rookie of the Year Award, receiving 13.5 of 24 possible votes. Milwaukee Brewers second baseman Pedro García is the runner-up with three votes. Bumbry, 26, is a combat veteran of the Vietnam War and was awarded a Bronze Star.

December

 * December 4:
 * The Baltimore Orioles acquire southpaw starting pitcher Ross Grimsley from the Cincinnati Reds along with minor-league catcher Wallace Williams for infielder Junior Kennedy, outfielder Merv Rettenmund and minor-league catcher William Wood. Grimsley will win 18 games for the 1974 Orioles.
 * The Kansas City Royals send three players—including infielder Kurt Bevacqua and outfielder Ed Kirkpatrick—to the Pittsburgh Pirates for veteran right-hander Nelson Briles and infielder Fernando González. Starting pitcher Briles is the key player in the deal, but he suffers through two injury-riddled seasons in Kansas City.
 * December 5:
 * The Montreal Expos and Los Angeles Dodgers pull off a major one-for-one trade when the Expos send record-setting relief pitcher Mike Marshall to Los Angeles for longtime Dodger centerfielder Willie Davis, a two-time NL All-Star and Gold Glove Award winner. In 1974, Marshall will shatter his own record for games pitched with 106 appearances, win 15 games, save 21 others (leading the Senior Circuit for the second straight year), capture the NL Cy Young Award (the first reliever to do so), and help the Dodgers win the pennant. Exactly one year from this day, Davis will be traded to the Texas Rangers despite a solid 1974 season with Montreal.
 * National League owners unanimously approve the transfer of the San Diego Padres to Washington, D.C., for the 1974 season under new ownership headed by Joseph Danzansky. However, "contingencies" involving the transaction—which center on the liability posed by the pending $84 million lawsuit brought by the city of San Diego—must be legally resolved by January 5, 1974, and the possibility exists that the league itself may temporarily take over the Padres, threatening the relocation plans.
 * December 6:
 * The Houston Astros trade centerfielder Jimmy Wynn to the Los Angeles Dodgers in exchange for veteran southpaw pitcher Claude Osteen and minor league pitcher David Culpepper. Known as the "Toy Cannon," Wynn, 31, has slugged 223 homers over 11 seasons with Houston. Osteen, 34, is a two-time 20-game winner who compiled 147 victories in nine seasons for the Dodgers, won a 1965 World Series ring, and made three NL All-Star teams.
 * The Chicago Cubs continue to remake their roster, sending veteran catcher Randy Hundley, a former All-Star and Gold Glover, to the Minnesota Twins for fellow backstop George Mitterwald.
 * December 7:
 * After parting with Willie McCovey six weeks earlier, the San Francisco Giants jettison another Baseball Hall of Famer, selling the contract of "the Dominican Dandy," Juan Marichal, to the Boston Red Sox. Ten-time All-Star Marichal has gone 238–140 (2.84 ERA) in 14 seasons with the Giants, won 20+ games six times and the 1971 Cy Young Award. The Giants will retire his #27 uniform.
 * The New York Yankees acquire outfielder Lou Piniella, along with pitcher Ken Wright, from the Kansas City Royals in exchange for 38-year-old veteran hurler Lindy McDaniel. Piniella, 30, will remain with the Yankees for the next 16 seasons as player, manager and general manager, and win two World Series rings.
 * The Boston Red Sox and St. Louis Cardinals complete their second multi-player trade this postseason. Boston sends pitchers John Curtis, Mike Garman and Lynn McGlothen to the Cardinals for pitchers Reggie Cleveland and Diego Segui and third baseman Terry Hughes.
 * December 11 – The Chicago Cubs, who have already traded Hall of Famer Ferguson Jenkins and former All-Stars Glenn Beckert and Randy Hundley, drop a bombshell on both the North and South sides of their city by dealing future Hall-of-Fame third baseman Ron Santo to the White Sox for pitchers Ken Frailing, Jim Kremmel (as a "PTBNL") and Steve Stone, and catcher Steve Swisher. Santo, 33, is a 14-year Cub mainstay, nine-time Senior Circuit All-Star and 5x winner of his league's Gold Glove Award. He smashed 337 homers in a Cub uniform.
 * December 13 – The New York Yankees defy Oakland Athletics' owner Charles O. Finley's promise to block any team from hiring Dick Williams as its 1974 manager by signing the two-time World Series-winning pilot to a three-year contract. The matter will go before American League president Joe Cronin at a December 19 hearing in Boston. Williams resigned from the Athletics immediately after the club's Series-clinching victory on October 21 with two years left on his contract.
 * December 20 – With only 11 days remaining before he retires as president of the American League, and only a day after he has conducted hearings on two hiring disputes, Joe Cronin issues rulings against the New York Yankees on two fronts:
 * He sides with Oakland Athletics owner Charles O. Finley in the finding that two-time World Series champion Dick Williams still has a valid contract with Oakland, and that Williams cannot sign to manage another American League team without Finley receiving compensation. The Yankees had named Williams their skipper seven days earlier, signing him to a lucrative three-year pact. Cronin's decision means that the Bombers' managerial chair is still vacant.
 * In addition, Cronin finds in favor of the Detroit Tigers in a grievance filed by the Yankees that contended that the Tigers had tampered with Ralph Houk, the Yanks' former manager who announced his resignation on September 29, then signed a three-year contract, upheld today by Cronin, to take over the Detroit squad on October 11.
 * December 28 – The fate of the San Diego Padres remains in limbo. Embattled, financially strapped owner C. Arnholt Smith announces that his earlier agreement to sell the five-year-old franchise to a Washington, D.C., ownership syndicate has collapsed. As a result, the team will not move to the U.S. capital in 1974, as had been expected. Instead, Smith has accepted an offer from a Los Angeles-based group headed by Marje Lindheimer Everett, owner of the Hollywood Park Racetrack. Everett and her partners affirm they intend to keep the Padres in San Diego pending National League owners' approval of the purchase. However, it's reported that some NL owners are firmly opposed to Everett's bid because of her involvement, as an unindicted co-conspirator, in a 1969 attempt to bribe Illinois governor Otto Kerner Jr.
