April 15 – The American League season opened with Boston Red Sox ace Babe Ruth pitching a four-hit, 7–1 victory over the Philadelphia Athletics. Shortly after, Boston manager Ed Barrow started Ruth's conversion to slugger by working him into seventy-two games as an outfielder–first baseman.
April 18 – Cleveland Indians center fielder Tris Speaker turned an unassisted double play against the Detroit Tigers. Eleven days later, Speaker duplicated the feat against the Chicago White Sox for the fourth unassisted double play of his career to set a franchise record that he would later share with teammate Elmer Smith.
May 14 – Sunday baseball was officially legalized in Washington, D.C. after district commissioners finally rescinded the ban in response to the large increase in the city's wartime population and the need for more recreational activities.
