National League final standings
- February 6 - Supporting the Wagner-Cashmore plan to build a $30-million downtown Brooklyn sports center, Brooklyn Dodgers owner Walter O'Malley promises to buy four million dollars worth of bonds.
- April 22 - The Philadelphia Phillies manage just three hits, but one of them is a three-run home run by Ted Kazanski, as Robin Roberts wins, 3–1, over Johnny Antonelli and the New York Giants.
- April 26 - Chico Carrasquel batted 2-for-4, including two runs, a grand slam and a career-high seven runs batted in, to guide the Cleveland Indians to a crushing 14–2 victory over the Kansas City Athletics. Early Wynn pitched a nine-strikeout, four-hit, two-run complete game to earn the victory, while Lou Kretlow allowed seven runs in four-plus innings to get the loss.
- May 2 - At Wrigley Field, the New York Giants defeat the Chicago Cubs, 6-5, in a 17-inning game in which 48 players see action—25 Giants and 23 Cubs. Chicago's Don Hoak sets a National League record by striking out six times in the game, which also features a record 11 intentional walks, including two each to the Giants' Willie Mays and Wes Westrum and the Cubs' Ernie Banks.
- May 12 - Carl Erskine tosses the second no-hitter of his career as the Brooklyn Dodgers blank the New York Giants, 3–0, at Ebbets Field. His first no-hitter came on June 19, 1952 against the Chicago Cubs at Ebbets Field.
- May 26 - Al Simmons died in Milwaukee, at the age of 54. A former Philadelphia Athletics outfielder as well as a three-time All-Star and two-time champion bat, Simmons posted a .334 average with 307 home runs and 1827 RBI in a 20-season major league career that included stints with six other teams besides the Athletics. Simmons was enshrined into the Hall of Fame in 1953.
- May 30 - Mickey Mantle of the New York Yankees narrowly misses hitting the first home run ever hit completely out of Yankee Stadium. With Hank Bauer and Gil McDougald on base in the fifth inning of Game One of a doubleheader against the Washington Senators, Mantle, batting left-handed against Pedro Ramos, hits a towering drive above the level of the stadium roof. However, a stiff wind cuts down the ball, which strikes the right-field facade, 18 inches (460 mm) above the level of the roof. The home run gives the Yankees a 3-1 lead; they go on to win 4-3.
- June 21 - Jack Harshman of the Chicago White Sox defeats Connie Johnson of the Baltimore Orioles 1-0 in a game in which both pitchers throw a one-hitter.
- June 27 - Chico Carrasquel went 5-for-6, including two doubles, two runs, and a game-ending RBI single in the 11th inning off Don Mossi, as the Cleveland Indians edged the Baltimore Orioles 12–11. Hal Brown was the winning pitcher in a 6 1⁄3-inning relief effort.
- July 10 - At Griffith Stadium, home of the Washington Senators, the National League topped the American League, 7-3, in the All-Star Game. Willie Mays, Stan Musial, Ted Williams, and Mickey Mantle all hit home runs.
- July 14 - Boston Red Sox pitcher Mel Parnell pitches a no-hitter in the Red Sox's 4-0 victory over the Chicago White Sox.
- July 25 - Roberto Clemente of the Pittsburgh Pirates hits the first, and so far only, walk-off inside-the park grand slam in major league history in a 9-8 win over the Chicago Cubs.
- August 2 - Herb Score shuts out the visiting New York Yankees‚ 4–0‚ for the Cleveland Indians seventh shutout in their last 12 games. Beto Avila gets the Indians on board with an inside-the-park home run in the third inning. An inning later, Preston Ward and Rocky Colavito hit back-to-back home runs and one out later Chico Carrasquel homers. The four solo homers in a shutout victory sets a major league record. Yankees starter Tom Sturdivant, who gave up the four homers, is the losing pitcher.
- August 8 - Robin Roberts wins his eighth straight game and his fourth in 10 days‚ as the visiting Philadelphia Phillies defeat the New York Giants‚ 9–3. Phillies shortstop Ted Kazanski lines an inside-the-park grand slam off Jim Hearn‚ just the fourth in club history to pace the attack.
- September 25 - Brooklyn Dodgers hurler Sal Maglie pitches a 5-0 no-hitter against the Philadelphia Phillies.
- September 30 - Chicago White Sox pitcher Jim Derrington becomes the youngest pitcher in modern history to start a game. He loses to the Kansas City Athletics, 7-6, at the age of 16 years and 10 months.
- October 8 - New York Yankees pitcher Don Larsen pitches a perfect game in Game 5 of the World Series against the Brooklyn Dodgers, in a 2-0 victory. It is only the fourth perfect game since 1900 and sixth in the history of Major League Baseball. To date it remains the only perfect game in baseball post-season history, and also the only no-hitter in the World Series.
- October 9 - The Dodgers bounce back. Brooklyn's Clem Labine comes out of the bullpen to pitch a 1-0 victory for the Dodgers in Game 6 of the World Series. Yankee Enos Slaughter misjudges Jackie Robinson's fly ball, and Jim Gilliam scores from second base; it turned out to be Robinson's last major league hit. The series is tied at 3 games apiece.
- October 10 - The New York Yankees defeat the Brooklyn Dodgers, 9-0, in Game 7 of the World Series to win their seventeenth World Championship, four games to three. Johnny Kucks goes the distance in the victory, allowing only three hits. Yogi Berra hits a pair of 2-run home runs and Bill Skowron hits a grand slam. Don Newcombe takes the loss, his fourth in Series competition. It was the last World Series game being played at Brooklyn's Ebbets Field. Yankees pitcher Don Larsen is named Most Valuable Player.
- October 24 - Birdie Tebbetts of the Cincinnati Reds is named National League Manager of the Year.
- October 25 - Chicago White Sox manager Marty Marion resigns. Al Lopez replaces him.
- Don Newcombe, who posted a 27-7 record with 139 strikeouts and a 3.06 ERA for the National League pennant-winning Brooklyn Dodgers, becomes the first MLB Cy Young Award winner. Only one pitcher will be selected each season for this prestigious pitching award until 1967, when each league will name a winner.
- Outfielder Charlie Peete, given a good shot at being the first black starter on the St. Louis Cardinals, is killed in a plane crash in Caracas, Venezuela. Peete, who hit .192 in 23 games for St. Louis in 1956, was returning from playing winter ball.
- November 28 - The Cleveland Indians name Kerby Farrell to replace Al Lopez as the team manager. Farrell won the Junior World Series as the pilot of the Double-A Indianapolis Indians.
- December 1 - Outfielder Frank Robinson of the Cincinnati Reds is unanimously voted the National League Rookie of the Year. In the American League, Chicago White Sox shortstop Luis Aparicio is voted Rookie of the Year with 22 points, beating out outfielders Tito Francona of the Baltimore Orioles and Rocky Colavito of the Cleveland Indians.
