May

• May 1 – Elmer Valo becomes the first AL player to hit two bases-loaded triples in a game when he leads the Philadelphia Athletics to a 15–9 win in the first of two games against the Washington Senators.

  • Appearing as a pinch hitter for Carl Furillo, Chuck Connors, making his major league debut, hits into a double play. After his career is aborted by injury, Connors would go on to greater fame starring on the TV show The Rifleman.
• May 3 – Taking advantage of the shortened fence installed by Chicago White Sox GM Frank Lane, the Washington Senators belt seven home runs – and need them all – in beating Chicago, 14–12 in 10 innings. This is the first time in MLB history a team has collected seven homers in an extra-inning contest. Clyde Vollmer leads the hit parade with a pair, followed by Mark Christman, Gil Coan, Al Evans, Eddie Robinson and Bud Stewart. The Sox get homers from Joe Tipton and Gus Zernial.
• May 4:
  • Chicago White Sox infielder Floyd Baker, who will play 874 games in his 13-year major league career, hits his only career home run off pitcher Sid Hudson, into "Home Run Lane", named for the new fence installed by Sox GM Frank Lane, in an 8–7 loss to the Washington Senators.
  • A day after the two teams played to a 13-inning, 14-14 tie, the Detroit Tigers beat the Boston Red Sox 5–1 behind Virgil Trucks' three-hitter. The Tigers shell Boston pitcher Mickey Harris for 14 hits in five and 2/3 innings.

The homer off Murry Dickson is the 300th for Mize. Reliever Hank Behrman, in for Sheldon Jones, pitches out of tight jams in the 9th and 10th innings to win the game. Wally Westlake is stranded in the 10th after reaching Behrman for a leadoff triple.
  • Before the start of a series with the New York Yankees, the Chicago White Sox abandon their trick left-field fence. The 5-foot chicken wire fence, erected to cut the distance by 20 feet, resulted in 11 home runs in eight games, but opponents hit seven of them. The AL will subsequently rule that fences cannot be moved more than once a season. The Yankees still win today, 7–5, to go 13–3. Tommy Henrich has the only homer, while Johnny Lindell, Yankees left fielder, twice makes catches that would've cleared the wire fence. Allie Reynolds, with help from Joe Page, is the winning pitcher.
  • At Cleveland, Bob Feller, making his first start since pitching two innings in the season opener and coming up with a sore shoulder, beats the Boston Red Sox 7–3. Cleveland scores six runs in the second inning, including a three-run home run by Ken Keltner off Jack Kramer. On the next pitch, rookie Minnie Miñoso, making his second start, hits his first major-league homer. Ted Williams and Bobby Doerr hit 8th-inning homers for the Red Sox, while Joe Gordon adds a homer in the 5th for Cleveland.
  • The Boston Red Sox acquire Al Zarilla from the St. Louis Browns for Stan Spence and cash consideration.
• May 6 – Philadelphia Athletics pitcher Bobby Shantz makes a sensational debut, tossing nine hitless innings in relief in a 13-inning 5–4 Athletics win over the Detroit Tigers.

• May 8:
  • At Shibe Park, the Cincinnati Reds score five runs in the ninth inning to take a 7–3 lead, but the Philadelphia Phillies tie to go into extra innings. Cincinnati then scores seven runs in the 12th to win 14–7.
  • Longtime St. Louis Cardinals owner Sam Breadon dies. Robert Hannegan, the man to whom he sold the club, will die on October 6.

  • At Tiger Stadium, the Detroit Tigers set back the first-place New York Yankees 4–1, behind the five-hit pitching of Ted Gray. Vic Raschi also allows just five hits, including a home run by Dick Wakefield, in taking the loss.
  • The first-place New York Giants win their seventh game in a row as pitcher Sheldon Jones stops the Chicago Cubs 7–2. Aided by ten walks and home runs by Sid Gordon and Willard Marshall, the Giants pin the loss on starter Ralph Hamner, who allows one hit in three innings.
• May 14 – Roy Sievers hits a home run and a double to drive in four runs, leading the St. Louis Browns' 8–3 victory over the Detroit Tigers. Slick-fielding Detroit first baseman Paul Campbell ties a major league record by making two unassisted double plays. While with minor league Montreal in 1941, Campbell started 26 DPs at 1B.
• May 15 – In the first game of a doubleheader at Comiskey Park, Chicago White Sox pitchers Bill Wight and Al Gettel shut out the Cleveland Indians 10–0 and 2–0.
  • Boston Braves pitcher Vern Bickford stops the Brooklyn Dodgers 4–0, allowing just four singles. One is by Gil Hodges, extending his hitting streak to 17 games. Jim Russell switch-hits a home run and double to pin the loss on Morrie Martin. The Braves start Al Lakeman at first base in place of Earl Torgeson, who separated his shoulder yesterday when he attempted to block Jackie Robinson on a double play. Torgeson will be operated on tomorrow and will be sidelined several months.
• May 16 – The Chicago Cubs receive infielder Bob Ramazzotti from the Brooklyn Dodgers in exchange for IF Harry Schenz and $25,000.
• May 22 – Brooklyn Dodgers pitcher Don Newcombe makes his first major league start a dandy, shutting out the Cincinnati Reds 3–0 in the first game of a doubleheader at Crosley Field. It's the first shutout in an NL debut in eleven years and extends Brooklyn's win streak at Cincinnati to 19 games going back to June 1947. Newcombe gives up hits to the first two batters, then allows just three more hits while walking none. He drives in two runs as well. In the second game, Ken Raffensberger then matches Newcombe by firing a one-hitter to beat Brooklyn 2–0, tossing only 83 pitches. The only hit is a leadoff single by Gil Hodges in the eighth inning. Raffensberger pitched two one-hitters against the Dodgers in the 1948 season.
• May 24 – Striking out the last six St. Paul batters, Mickey McDermott of minor league Louisville fans a total of 20 for a new league record. McDermott wins 3–1, striking out the side in the 3rd, 5th, 6th, 8th, and 9th innings.
• May 27 – The Cleveland Indians start the season so badly, 12–17, that owner Bill Veeck arranges a "Second Opening Day". Behind pitcher Al Benton, Cleveland make it a success, beating the Chicago White Sox 4–0. The Indians do rise to second place, within two 1/2 games of the top, but they will finish third, eight games back.
• May 28 – Chicago White Sox rookie left fielder Gus Zernial breaks his collarbone making a diving catch against the Cleveland Indians. He will be out of action for two months. Cleveland push across a run in the ninth inning against Howie Judson to take a 3–2 victory. Early Wynn is the winning pitcher.

June

• June 2 – At Shibe Park, the Philadelphia Phillies hit five home runs during the same inning (the 8th) in a 12–3 victory over the Cincinnati Reds, tying the major league mark set by the 1939 New York Giants. Andy Seminick belts two, while Del Ennis, Willie Jones and Schoolboy Rowe have one each. Jones adds a triple as Granny Hamner's double jumps the extra bases total to 18, still a record. Seminick collects three HR overall.
• June 5 – Commissioner Happy Chandler lifts the ban on all players who jumped to the Mexican League, starting in 1946. Only Sal Maglie will make a significant mark after the exile. Lou Klein will be the first jumper to make a major-league box score, successfully pinch-hitting on June 16.

• September 26 – Before 67,434 at Yankee Stadium, the Boston Red Sox survive a rhubarb-filled 7–6 win when Johnny Pesky scores on a disputed squeeze play.

October

• Coming into the last weekend of the season, the Boston Red Sox are one game ahead of the New York Yankees, with the only games left for those teams being two against each other, thus there can be no playoff for the American League pennant.
