ピッツバーグ・パイレーツが初めてリーグ優勝したのはいつ
The franchise joined the NL in its eighth season in 1887 and was competitive from its early years, winning three NL titles from 1901 to 1903, playing in the inaugural World Series in 1903 and winning their first World Series in 1909 behind Honus Wagner. The Pirates have had many ups and downs during their long history, most famously winning the 1960 World Series against the New York Yankees on a game-winning walk-off home run by Bill Mazeroski, the only time that Game 7 of the World Series has ever ended with a home run. They also won the 1971 World Series, led by the talent of Roberto Clemente, and the 1979 World Series under the slogan "We Are Family", led by "Pops" Willie Stargell.
