The regular season ended on October 3, with the San Francisco Giants and New York Yankees as the regular season champions of the National League and American League, respectively.
The Giants defeated the Los Angeles Dodgers in a regular season best-of-three tiebreaker, for the National League title in three games, after both teams finished their 162-game schedules with identical 101–61 records.
In the seventh iteration of this World Series matchup, and their first since the Giants relocated to San Francisco from New York, the Yankees defeated the Giants, four games to three, capturing their 20th championship in franchise history, winning back-to-back World Series.
Due to the Los Angeles Dodgers and San Francisco Giants finishing with the same record of 101–61, a best-of-three tie-breaker was scheduled, to be considered an extension of the regular season, and took place between October 1 and October 3.
CBS and NBC continued to air weekend Game of the Week broadcasts.
