Pittsburgh Pirates
baseball team and Major League Baseball franchise in Pittsburgh, Pennsylvania, United States
The Pittsburgh Pirates are an American professional baseball team based in Pittsburgh. The Pirates compete in Major League Baseball (MLB) as a member club of the National League (NL) Central Division. Founded as part of the American Association in 1881 under the name the Allegheny Base Ball Club of Pittsburgh, the club joined the National League in 1887 and was a member of the National League East from 1969 through 1993. The Pirates have won five World Series championships, nine National League pennants, nine National League East division titles and made three appearances in the Wild Card Game.
The Pirates were among the best teams in baseball at the start of the 20th century, playing in the inaugural World Series in 1903 and winning their first title in 1909 behind Honus Wagner. The Pirates won their second title in 1925 and were the first team in North American sports history to overcome a 3–1 series deficit to win a playoff series. The club won the 1960 World Series against the New York Yankees on a 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 won again in 1971 behind Roberto Clemente, the first Latin-American enshrined in the National Baseball Hall of Fame, and in 1979 under the leadership of Willie Stargell.
Since their last World Series in 1979, the Pirates have largely endured a period of great struggle. Since then, they have only had eleven winning seasons, six postseason appearances, three division titles, and have advanced just once in the postseason with a victory in the 2013 National League Wild Card Game.
