National League final standings
- January 23 – Guido Rugo sells his interest in the Boston Braves to copartners Lou Perini and treasurer Joe Maney.
- January 26 – The baseball writers vote Mel Ott and Jimmie Foxx into the Hall Of Fame.
- March 10 – The St. Louis Browns reveal plans to move the club to Milwaukee because of poor attendance.
- February 5 – California governor Earl Warren rejects the rumor that he is a candidate for the MLB Commissioner position.
- March 12 – Baseball commissioner Happy Chandler loses his bid to remain in office. Chandler, who started his term as commissioner in 1945, is voted down, 9–7, in a tally of owners. He will be succeeded by Ford C. Frick.
- March 21 – During spring training, Pittsburgh Pirates lefty first baseman Dale Long makes his first appearance as a catcher in an exhibition game at San Diego, California, after Pirates general manager Branch Rickey decided to flaunt tradition and try him as a catcher for the foreseeable future. Pretty soon, Long joined the St. Louis Browns on waivers and went back to first base. Eventually, he would catch two games in 1958 with the Chicago Cubs, using a first baseman's mitt.
- April 17 – At Shibe Park, the Philadelphia Athletics and the Washington Senators play the first Opening Day night game in American League history. The Senators prevailed, 6–1, behind the solid pitching of Cuban 40-year-old Connie Marrero, as his batterymate Mickey Grasso hits a three-run home run. Marrero pitches nine strong innings, allowing one earned run on seven hits and two walks while striking out six batters. Bobby Shantz is the losing pitcher.
- May 1 – On Mother's Day, New York Yankees rookie Mickey Mantle hit the first home run of his career off Randy Gumpert in an 8–3 victory over the Chicago White Sox at Comiskey Park. In the same game, Cuban third baseman and former Negro Leagues star Minnie Miñoso becomes the first black player in White Sox franchise history. In his first Major League at-bat, Miñoso hit a home run while facing Yankees starter Vic Raschi.
- May 2 – At Briggs Stadium, Philadelphia Athletics pinch hitter Lou Limmer stepped into the batters box to face Detroit Tigers pitcher Saul Rogovin. The 6'2" right-hander peered in to get the signal from catcher Joe Ginsberg, nodded assent, and went into the windup. Around came the arm, in came the pitch and Limmer swung, sending a drive to deep right that cleared the fence for a home run. After all, pinch hit home runs are not unique, but what is unique is that the pitcher, the catcher, and the hitter were all Jewish. It is the only known time in Major League Baseball that has occurred.
- May 6 – In the second game of a doubleheader, Cliff Chambers pitches a no-hitter, as the Pittsburgh Pirates top the Boston Braves, 3–0.
- June 4 – Gus Bell hits for the cycle, droves in three runs and scores two more, to lead the Pittsburgh Pirates to a 12–4 victory over the Philadelphia Phillies at Connie Mack Stadium.
- July 1 – In the first game of a doubleheader, Bob Feller tosses the third no-hitter of his career for the Cleveland Indians in a 2–1 win over the Detroit Tigers.
- July 10 – Exploding for a record four home runs, the National League trounces the American League, 8–3, at the annual All-Star Game, at Briggs Stadium in Detroit. Pittsburgh Pirates' slugger Ralph Kiner hits a home run for the 3rd year in a row.
- July 12 – New York Yankees hurler Allie Reynolds pitches a no-hitter against the Cleveland Indians in a 1–0 win.
- July 17 – After pitching for Bill Veeck in Cleveland in 1948, Satchel Paige rejoins him with the St. Louis Browns.
- July 28 – Clyde Vollmer, who started the month on the bench, continues his explosive fireworks against the Indians. Vollmer singles in the tying run in the 15th inning and then in the 16th hits a grand slam off reliever Bob Feller for an 8–4 Red Sox win. The grand slam is the latest hit in a game in major-league history. Mickey McDermott pitches all 16 innings for the Sox, striking out 15 and walking one.
- August 11 – Robin Roberts of the Philadelphia Phillies beat the New York Giants, 4–0, dropping the Giants 13.5 games behind the first-place Brooklyn Dodgers.
- August 19 – Bill Veeck, the showman and maverick owner of the St. Louis Browns, pulls off one of the greatest stunts in baseball history. In the second game of a doubleheader against the Detroit Tigers, Veeck sends Eddie Gaedel to the plate as a pinch-hitter for leadoff batter Frank Saucier. At 3 feet 7 inches (1.09 m) tall, Gaedel became the shortest player in baseball history. Due to his extremely small strike zone, Gaedel walked on four consecutive pitches and was immediately pulled for a pinch-runner. American League president Will Harridge, saying Veeck was making a mockery of the game, voided Gaedel's contract the next day. Detroit went on to win the game, 6–2.
- September 1 – New York Giants outfielder Don Mueller hit three home runs and drove in five runs in an 8–1 victory over the Brooklyn Dodgers at Polo Grounds. Sal Maglie was the winning pitcher. Dodgers starter Ralph Branca‚ coming off two consecutive shutouts‚ lasted only four innings.The only run for Brooklyn came on a hit by pitch, when Maglie hit Jackie Robinson with the bases loaded in the third inning. Besides, Whitey Lockman was plunked twice by Dodgers relievers Bud Podbielan and Phil Haugstad. In a flashy fielding play, shortstop Alvin Dark and second baseman Eddie Stanky combined in the fifth inning on a triple play off a liner by Dodgers shortstop Pee Wee Reese.
- September 14 – Bob Nieman of the St. Louis Browns became the first player in Major League history to hit two home runs in his debut. Nieman will be joined by Bert Campaneris (1964) and Mark Quinn (1999) in the select group.
- September 28 – Allie Reynolds turns in the second no-hitter of his career, and his second this season, as the New York Yankees blank the Boston Red Sox, 8–0.
- October 3 – The New York Giants had been thirteen and one-half games behind the National League leading Brooklyn Dodgers in August, but under Leo Durocher's guidance and with the aid of a sixteen-game winning streak, caught the Dodgers to tie for the lead with two days left in the season. As both teams won their last two games, they ended up tied. The two teams play a best-of three playoff. In Game 3 with one out in the ninth inning and runners on second and third, the Giants were down 4–2 to the Dodgers when Bobby Thomson hit a home run to win the game 5–4. The "Shot heard 'round the world" clinched the National League pennant for the Giants, and WMCA-AM radio announcer Russ Hodges' frantic "The Giants win the pennant!", said four times consecutively, is one of the most famous home run calls in baseball history.
- October 10 – The New York Yankees defeat the New York Giants, 4–3, in Game 6 of the World Series to win their third consecutive World Championship, and fourteenth overall. Just before the game, Giants manager Leo Durocher turns over a letter he received to Ford Frick that offered the Giants manager a $15,000 bribe "if the Giants managed to lose the next 3 games".
- October 17 – The Yomiuri Giants win the Japan Series over the Nankai Hawks. The Giants went on to win the Central League pennant 19 times in the next 23 years, including nine in succession (1965–73).
- November 1 – Brooklyn Dodgers catcher Roy Campanella was named National League Most Valuable Player, the first of three awards he would receive during his Hall of Fame career. During the season, Campanella hit a .325 batting average with 33 home runs and 108 run batted in.
- November 10 – In Tokyo, Japan 50,000 fans are on hand as an American All-Star team battles a Central League All-Star team. Joe DiMaggio hits a 400-foot home run in the eighth inning to tie the game at 1–1, then his younger brother Dom laces an RBI-triple in the ninth and later scores to give the Americans a 3–2 victory. The Americans have won 12 games and tied one.
- November 23 – The New York Yankees send young catcher Clint Courtney to the St. Louis Browns in exchange for pitcher Jim McDonald. Courtney, regarded as the first major league catcher to wear eyeglasses, had appeared in one game for New York.
- November 27 – In an eight-player trade, the St. Louis Browns send C Sherm Lollar, P Al Widmar and IF Tom Upton to the Chicago White Sox in exchange for C Gus Niarhos, P Dick Littlefield, 1B Gordon Goldsberry, SS Joe DeMaestri and OF Jim Rivera. Rivera, a favorite of Browns manager Rogers Hornsby, will return to the Sox in eight months.
- November 28 – The St. Louis Browns trade Niarhos, along with OF Ken Wood to the Boston Red Sox for C Les Moss and OF Tom Wright. The Browns also sign Marty Marion, former St. Louis Cardinals shortstop/manager.
- December 11 – Three-time MVP and 13-time All Star center fielder Joe DiMaggio officially retired as a member of the New York Yankees. In a 13-season career for the club, DiMaggio posted a .325 batting average with 361 home runs and 1,537 runs batted in in 1,736 games played. A future Hall of Famer, his 56-game consecutive-game hitting streak in the 1941 season is the longest in Major League Baseball history and will stand as one of the all-time best diamond achievements.
