The 1973 World Series matched the defending champions Oakland Athletics against the New York Mets with the A’s winning in seven games to repeat as World Champions.
The New York Mets won the National League East division by 1 1⁄2 games over the St. Louis Cardinals then defeated the Cincinnati Reds, three games to two, in the National League Championship Series. The Oakland Athletics won the American League West division by six games over the Kansas City Royals then defeated the Baltimore Orioles, three games to two, in the American League Championship Series.
This was the first World Series in which all weekday games started at night. The three weekday games the previous yearwere scheduled to be played at night, but a postponement of Game 3 eliminated the scheduled off day between Games 5 and 6, and Major League Baseball moved Game 5 to an afternoon start to allow the teams enough time for traveling.
This was the last World Series in which each team produced and sold its own game programs for its home games. Starting in 1974, Major League Baseball printed an official World Series program that was sold in both stadiums.
