1909 Pittsburgh Pirates season
The 1909 Pittsburgh Pirates season was the 28th season for the Pittsburgh Pirates franchise, during which they won the National League pennant with a record of 110–42 and their first World Series over the Detroit Tigers. Led by shortstop Honus Wagner and outfielder-manager Fred Clarke, the Pirates scored the most runs in the majors. Wagner led the league in batting average, on-base percentage, slugging percentage, and runs batted in. Pirates owner Barney Dreyfuss opened the Pirates' new ballpark, named Forbes Field, on June 30, 1909.
The Pirates' 110 wins remain a team record, a record they set in the last game of the season by beating the Cincinnati Reds 7–4 in muddy conditions on October 5. It is in fact the best regular season win percentage by any World Series winning team.

1909 World Series
In the World Series, Pittsburgh faced the American League champion Detroit Tigers, led by triple crown winner Ty Cobb. The matchup was largely billed as one between the major leagues' two superstars. Wagner thoroughly outplayed Cobb, and rookie Babe Adams won all three of his starts, as the Pirates won in seven games.
