Cincinnati Reds vs Pittsburgh Pirates

Only two National League franchises won the World Series during the 1970 s the Pirates and the Reds. And since they often had to go through one another to get there, they were one of the greatest rivalries in modern history. The Western Division-winning Reds swept the Eastern Division-winning Pirates to win the pennant in 1970 and 1975 and also knocked them out of the NLCS in 1972. Not to be outdone, Willie Stargell and the We Are Fam-a-lee Pirates swept the Reds in October 1979 on their way to a second World Series win in nine years.
