The 1946 major league baseball season began on April 16, 1946. The regular season ended on October 3, with the St. Louis Cardinals and Boston Red Sox as the regular season champions of the National League and American League, respectively. The Cardinals defeated the Brooklyn Dodgers in a regular season best-of-three tiebreaker, for the National League title, after both teams finished their 154-game schedules with identical 96–58 records. It was Major League Baseball's first-ever regular season tie-breaker. The postseason began with Game 1 of the 43rd World Series on October 6 and ended with Game 7 on October 15. The Cardinals defeated the Red Sox, four games to three.
This was the last MLB season to be played under the color barrier, as Jackie Robinson would make his debut with the Brooklyn Dodgers to start the following baseball season.
The 1946 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.
Opening Day took place on April 16, featuring all sixteen teams, continuing the trend from the previous season. The final day of the scheduled regular season was on September 29, which saw all sixteen teams play, the first time since 1944. Due to the Brooklyn Dodgers and St. Louis Cardinals finishing with the same record of 96–58, a best-of-three tie-breaker was scheduled, to be considered an extension of the regular season. The Cardinals swept the series in two games, on October 1 & 3. The World Series took place between October 6 and October 15.
