Back on this date (October 17) in 1971, the Pittsburgh Pirates defeated the Baltimore Orioles 2-1 in Game Seven of the World Series to win their fourth of five championships. The Buccos also won in 1909, 1925, 1960, and 1979.
The 1971 team was already world famous for being the first squad to ever field and all-minority lineup on September 1 earlier that year, etching themselves into the history books. And then they added to their legacy with the Series win over Baltimore in a back-and-forth seven-gamer that saw Pittsburgh lose the first two games before roaring back to take three in a row, with the teams splitting the last two contests.
