The 1933 Major League Baseball season was contested from April 12 to October 7, 1933. The New York Giants and Washington Senators were the regular season champions of the National League and American League, respectively. The Giants then defeated the Senators in the World Series, four games to one.
The season featured eight players hitting for the cycle, tied for the most of any single major league season. It was also the last season before the Senators and Philadelphia Athletics became perennial American League cellar-dwellers. The Senators would have only four more winning seasons in Washington D.C. and would not return to the World Series until 1965 as the Minnesota Twins, while the Athletics would have only four winning seasons until moving to Oakland in 1968, winning only 40.2 percent of their games over 34 seasons.
