The City of Pttsburgh's first nationally recognized professional baseball club was the Pittsburgh Alleghenies which joined the National League in 1887. The Alleghenies became the Pirates in 1891 when they were accused of "pirating" players from the rival American Association (later the American League). The name stuck. The Pirates participated in the first World Series in 1903 losing to the Boston Red Sox five games to three. The Pirates went on to win World Series titles in 1909, 1925, 1960, 1971 and 1979.
