Alleghenys' signing of Bierbauer was "piratical". This incident (discussed at some length in The Beer and Whisky League, by David Nemec, written in 1994) quickly accelerated into a schism between the leagues that contributed to the demise of the A.A. Although the Alleghenys were never found guilty of wrongdoing, their allegedly "piratical" act gained them the occasional nickname "Pirates" starting in 1891. Within a few years, the nickname caught on with Pittsburgh newspapers. The nickname was first acknowledged on the team's uniforms in 1912. After almost two decades of mediocre baseball, the Pirates' fortunes began to change at the turn of the 20th century. The Pirates acquired several star players from the Louisville Colonels, who were slated for elimination when the N.L. contracted from 12 to 8 teams. (The franchises did not formally consolidate; the player acquisitions were separate transactions.) Among those players was Honus Wagner, who would become one of the first players inducted to the Baseball Hall of Fame. The Pirates were among the best teams in baseball in the early 1900s, winning three consecutive National League pennants from 1901 to 1903 and participating in the first modern World Series ever played, which they lost to Boston. The Pirates returned to the World Series in 1909, defeating the Detroit Tigers for their first-ever world title. That year, the Pirates moved from Exposition Park to one of the first steel and concrete ballparks, Forbes Field. As Wagner aged, the Pirates began to slip down the National League standings in the 1910s, culminating in a disastrous 51–103 record in 1917; however, veteran outfielder Max Carey and young players Pie Traynor and Kiki Cuyler, along with a remarkably deep pitching staff, brought the Pirates back to relevance in the 1920s. The Pirates won their second title in 1925, becoming the first team to come back from a 3–1 deficit in the World Series. The Pirates returned to the World Series in 1927 but were swept by the Murderer's Row Yankees. The Pirates remained a competitive team through the 1930s but failed to win the pennant, coming closest in 1938 when they were passed by the Chicago Cubs in the final week of the season. Despite the prowess of Ralph Kiner as a slugger, the Pirates were mostly miserable in the 1940s and 1950s. Branch Rickey was brought in to rebuild the team, which returned to the World Series in 1960. They
