Founding & Early Years (1882–1900)
The franchise began in 1882 as the Pittsburgh Alleghenys, a founding member of the American Association. The team played its early games at Exposition Park on Pittsburgh's North Shore before moving to Recreation Park. In 1887, the club jumped to the National League, beginning a membership that has lasted well over a century.
The name "Pirates" arrived in 1891, born from controversy. After the Players' League folded, Pittsburgh signed second baseman Lou Bierbauer — whom the Philadelphia Athletics believed was still their property. The Athletics cried foul, calling Pittsburgh's actions "piratical." The name stuck, and the Pittsburgh Pirates were officially born.
The Wagner Era & First Championship (1900–1920)
The arrival of Honus Wagner transformed the franchise. Widely considered the greatest shortstop in baseball history, Wagner led the Pirates to four National League pennants and their first World Series title in 1909, defeating Ty Cobb and the Detroit Tigers in seven games. Wagner hit .339 that season and drove in 100 runs — at age 35.
The 1909 championship team was built on pitching and speed. Babe Adams, a rookie, won three complete games in the World Series — a feat that has never been matched. The Pirates remained competitive through the 1910s but couldn't recapture the magic of that first title run.
The Roaring Twenties & Second Crown (1920–1940)
After a brief downturn, the Pirates rebounded in the 1920s behind a powerful lineup that included Pie Traynor, Kiki Cuyler, and brothers Paul and Lloyd Waner. The Waners — "Big Poison" and "Little Poison" — formed one of the most prolific sibling duos in baseball history, both collecting over 3,000 career hits.
The 1925 World Series saw the Pirates face the Washington Senators, led by the legendary Walter Johnson. Down three games to one, Pittsburgh stormed back to win three straight, taking Game 7 in a rain-soaked 9-7 thriller at Forbes Field. It was the franchise's second championship and the first World Series comeback from a 3-1 deficit.
Postwar Struggles & the Mazeroski Miracle (1940–1970)
The decades following World War II were lean for Pittsburgh. The Pirates finished in the first division just twice between 1946 and 1957, often dwelling near the bottom of the National League. But the arrival of Roberto Clemente in 1955 signaled a new era. The young Puerto Rican outfielder would become not only one of baseball's greatest players but one of its most important figures.
In 1960, the Pirates shocked the baseball world. They won the National League pennant and faced the mighty New York Yankees — winners of 10 of the previous 14 World Series — in the Fall Classic. The series went to a decisive Game 7 at Forbes Field. In the bottom of the ninth inning, with the score tied 9-9, second baseman Bill Mazeroski drove a Ralph Terry pitch over the left-field wall at Forbes Field for the only Game 7 walk-off home run in World Series history. The Pirates were champions.
The Clemente Era & 1971 Champions
Throughout the 1960s, Roberto Clemente established himself as the premier right fielder in baseball — winning four batting titles, collecting his 3,000th hit, and earning 12 consecutive Gold Glove Awards. In 1971, he led the Pirates back to the World Series against the heavily favored Baltimore Orioles.
Clemente hit .414 in the series, collecting at least one hit in every game, and the Pirates won in seven. Clemente was named World Series MVP. Tragically, just over a year later, on New Year's Eve 1972, he died in a plane crash while delivering humanitarian aid to earthquake victims in Nicaragua. He was 38. The Baseball Hall of Fame waived its five-year waiting period and inducted him immediately.
We Are Family (1970s–1980s)
The late 1970s brought another golden era. Led by the charismatic Willie Stargell, the 1979 Pirates adopted Sister Sledge's "We Are Family" as their anthem and rode a wave of chemistry and clutch hitting to another World Series. Trailing the Orioles three games to one — again — they stormed back to win in seven, with Stargell claiming both the NL MVP and World Series MVP awards at age 39.
The Modern Era (1990s–Present)
The early 1990s brought three consecutive NL East titles (1990–1992) behind Barry Bonds, Bobby Bonilla, and Doug Drabek. Bonds won two MVP awards in Pittsburgh before departing in free agency. The years that followed were difficult — the Pirates endured a record 20 consecutive losing seasons from 1993 to 2012, the longest such streak in North American professional sports history.
The drought finally broke in 2013, when a young core led by Andrew McCutchen — the 2013 NL MVP — returned the Pirates to the postseason. They made three consecutive Wild Card appearances (2013–2015), rekindling a connection with fans who had waited a generation for competitive baseball. Today, the franchise continues to build toward its next championship chapter, anchored by a passionate fanbase and one of the most beautiful ballparks in the sport.
