February

March

• March 8 – Philadelphia Phillies pitcher Hugh Mulcahy becomes the first Major League Baseball player drafted into the Armed Forces in the draft established by President Roosevelt in anticipation of World War II. More than 100 major leaguers will be drafted within the next two years, and two of them, Washington Senators outfielder Elmer Gedeon and Philadelphia Athletics catcher Harry O'Neill, will be killed in action.
• March 23 – New York Yankees outfielder Joe DiMaggio, a hold out and late arrival in spring training, plays his first Grapefruit League game.

April

• April 13 – In the final pre-season tune-up game, the New York Yankees win their 3rd game in a row over the host Brooklyn Dodgers at Ebbets Field, 3–0. The Dodgers had come into this final series with an 11-game winning streak, including four games against the Yankees at their training camp.
• April 15 – Shortstop Lou Stringer made four errors in his debut with the Chicago Cubs, setting a National League record for a player in his first game. Stringer does better on offense, adding a pair of hits and two runs batted in. Chicago beat the Pittsburgh Pirates, 7–4, backed by strong pitching from starter Claude Passeau and a clutch home run by Bill Nicholson. Besides, the win is the first for Jimmie Wilson while making his managerial debut.
• April 20 :
  • At the Polo Grounds, the New York Giants attracted an attendance of 56,314, to date the biggest crowd ever to view a single game, even though they lost to the Brooklyn Dodgers, 10–9.
  • The Brooklyn Dodgers became the first club in Major League Baseball history to wear a protective headgear, as each player cap featured a special plastic lining designed to fend off the effects of beanballs. It was a cautious response to the numerous beanball wars of the 1940 season which saw hospitalized players such as Joe Medwick and Billy Jurges, among others. Nevertheless, the liners in the caps are thin enough to be hardly noticeable, so most players disdained the protection.

May

• May 15 – In the first inning, Joe DiMaggio of the New York Yankees singles against the Chicago White Sox to start his 56-game hitting streak.
• May 20 – Chicago White Sox outfielder Taft Wright set an American League record after driving in at least one run in thirteen consecutive games. During the streak, Wright recorded 22 runs batted in although in six of the games he drove in a run without collecting a hit.

June

• June 1 – Mel Ott's two-run homer, the 400th of his career and his 1,500th RBI, gives the New York Giants a 3–2 win over the Cincinnati Reds.
• June 6 – The New York Giants became the first team in Major League history to use plastic batting helmets during a doubleheader against the Pittsburgh Pirates. Although the Giants batters appeared comfortable in their new headgear at the plate, they still went on to lose both games by scores of 5–4 and 4–3.

July

• July 8 – At the All-Star Game at Detroit's Briggs Stadium, Boston's Ted Williams, hitting .405 at the break, homers off Chicago Cubs pitcher Claude Passeau with 2 outs and 2 on in the 9th inning to give the American League a dramatic 7–5 victory. Williams' 4 RBIs are matched by National League shortstop Arky Vaughan, who hits home runs in the 7th and the 8th.
• July 16 – Joe DiMaggio's hitting streak ends at 56 games against the Cleveland Indians.
• July 25 – Lefty Grove of the Boston Red Sox earns his 300th career win, which is also his last.

August

• August 19 – Pittsburgh Pirates manager Frankie Frisch was ejected from the second game of a double header after appearing on the field waving an umbrella to protest the playing conditions at Ebbets Field, home of the Brooklyn Dodgers. As a result, American artist Norman Rockwell later transformed the humorous argument into a famous oil painting titled Bottom of the Sixth.

September

• September 17 – 20-year old Stan Musial makes his major league debut with the St. Louis Cardinals.
• September 28 – Entering the last day of the season, Ted Williams of the Boston Red Sox was hitting .3995, which would have been good for a .400 average. However, Williams decided to play in both games of a double-header at Shibe Park against the Philadelphia Athletics to make it completely legitimate; he would go 6 for 8 in the two games to leave his average at .406. It remains the last time any player has hit .400 in a season.
• September 29 – The Fort Custer team won the national amateur championship of the American Baseball Congress with a 3–2 victory over the Charlotte, North Carolina, team. It was the last time the amateur World Series was held until after the war.

At age 24, Boudreau became the youngest player to manage a team in the 20th century. Jim McCormick, the first ballplayer born in Scotland to appear in a major league game, managed Cleveland in 1879 at age 23.
• November 27 – in a controversial vote, Joe DiMaggio of the New York Yankees is named American League MVP over Ted Williams of the Boston Red Sox (291 points for DiMaggio, 254 for Williams). DiMaggio, who set a 56-game hitting streak record in the season, batted .357 with 30 home runs and led the AL in RBI (125), while Williams finished even stronger to close the season with a majors leading .406 average and 120 RBI, while leading the American League in home runs (37), runs (135), OBP (.553) and SLG (.735). Both the 56-game hitting streak and the .400 plateau have not been touched since.

• December 7 – The secret vote by the AL owners to move the St. Louis Browns franchise to Los Angeles, scheduled for the week of December 8, is thwarted by the Japanese attack on Pearl Harbor on Sunday, December 7, thereby plunging the U.S. into World War II and keeping the Browns in St. Louis for another dozen seasons.^[1]
