Riverfront Stadium quickly earned a place in Cincinnati's century-long baseball tradition as the home of one of the best teams in baseball history. The World Series had visited the Reds' previous home, Crosley Field, just three times in its final 31 years, (1939, 1940, 1961) but it came to Riverfront in its first year (1970) and a total of four times in the stadium's first seven years, with the Reds winning back-to-back championships in 1975 and 1976. The World Series would return in 1990, with Cincinnati winning the first two of a four-game sweep of the Oakland Athletics at Riverfront.
