were outscored over the course of the series by the Yankees, yet the Pirates won on a walk-off home run by Bill Mazeroski in the bottom of the 9th inning in Game 7. As of 2022, it is the only Game 7 walk-off home run in World Series history. Led by right fielder Roberto Clemente, the Pirates remained a strong team throughout the 1960s but did not return to the World Series until 1971. Playing in the new Three Rivers Stadium, the Pirates defeated the favored Baltimore Orioles behind Clemente's hitting and the pitching of Steve Blass. In the same year on September 1, the Pirates became the first team to field an all-Black and Latino lineup. Despite Clemente's death after the 1972 season, the Pirates were one of the dominant teams of the decade, winning the newly created National League East in 1970, 1971, 1972, 1974, 1975, and 1979. Powered by sluggers such as Willie Stargell, Dave Parker, and Al Oliver, the team was nicknamed "The Lumber Company." Behind Stargell's leadership and the disco song "We Are Family" (which the team adopted as its theme song), the Pirates came back from a 3–1 deficit to once again defeat the Orioles in the 1979 World Series for the franchise's fifth championship. During the 1979 championship season, a Pittsburgh player was designated as Most Valuable Player in every available category: All-Star Game MVP (Dave Parker), NLCS MVP (Willie Stargell), World Series MVP (Willie Stargell), and National League MVP (Willie Stargell, shared with Keith Hernandez of St. Louis). The Pirates sank back into mediocrity in the 1980s and returned to post-season play in the early 1990s behind young players like Barry Bonds, Bobby Bonilla, and Doug Drabek. The Pirates won three straight division titles from 1990 to 1992 but lost in the National League Championship Series each time, notably coming within one out of advancing to the World Series in 1992. Several of the team's best players, including Bonds and Drabek, left as free agents after that season. With salaries rising across baseball, the small-market Pirates struggled to keep pace with the sport and they posted a losing record for 20 consecutive seasons, a record among North American professional sports teams. Even the opening of a new stadium in 2001, PNC Park, did little to change the team's fortunes. The Pirates finally returned to the postseason in 2013 behind National League MVP
