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.
