The 1970 World Series matched the American League champion Baltimore Orioles (108–54 in the regular season) against the National League champion Cincinnati Reds (102–60), with the Orioles winning in five games.
In this series Emmett Ashford became the first African American to umpire in the Fall Classic. It also featured the first World Series games to be played on artificial turf, as Games 1 and 2 took place at Cincinnati’s first-year Riverfront Stadium.
This was the last World Series in which all games were played in the afternoon. Also this was the third time in a World Series where a team leading 3–0 in the series would fail to complete the sweep by losing game 4 but still win game 5 to win the series. 1910 and 1937 were the others.
