The 1928 major league baseball season began on April 10, 1928. The regular season ended on September 30, with the St. Louis Cardinals and New York Yankees as the regular season champions of the National League and American League, respectively. The postseason began with Game 1 of the 25th World Series on October 4 and ended with Game 4 on October 9. The Yankees swept the Cardinals in four games.
The 1928 schedule consisted of 154 games for all teams in the American League and National League, each of which had eight teams. Each team was scheduled to play 22 games against the other seven teams of their respective league. This continued the format put in place since the 1904 season (except for 1919) and would be used until 1961 in the American League and 1962 in the National League.
American League Opening Day took place on April 10 with the Boston Red Sox and Washington Senators playing, while National League Opening Day took place the following day. The final day of the regular season was on September 30. The World Series took place between October 4 and October 9.
The National League reimplemented the early-1920home run rule, which states that balls are to be called based on where the ball crosses the outfield fence regarding home runs. This rule was only for balls which landed in the stands. Balls which completely left the ballpark were to be judged based on where the ball flew out of sight. The American League would implement the outfield fence portion of the home run rule in 1931, and would extend this interpretation to balls which leave the ballpark completely.[1]
