The 1927 Pittsburgh Pirates season was a season in American baseball. That year, the Pirates won the National League pennant, which was their second in three years and their last until 1960. The team included five future Hall of Famers: Paul Waner, Lloyd Waner, Pie Traynor, Kiki Cuyler, and 20-year-old rookie Joe Cronin (who played just 12 games). In the World Series, however, Pittsburgh was no match for the New York Yankees. They were swept in four games.
