The Chicago Whales were a Federal League baseball club in Chicago from 1914 to 1915. The Whales won the Federal League championship in 1915.
Founded by Charles Weeghman , the Whales finished 1 1/2 games behind the Indianapolis Hoosiers in the inaugural season for the league, during which the team was known as the Chicago Federals. Prior to the start of the season, Weeghman built a stadium for the team, called Weeghman Field. Now used by the Chicago Cubs, it is the only Federal League stadium still in use.
In the League's second and final season, the Whales won the championship, finishing .001 percent ahead of the St. Louis Terriers . When Kenesaw Mountain Landis brokered a deal between the Federal League, American League and National League that ended the Federal League's existence, Weeghman was allowed to purchase the Cubs.
Many Whales players had American and National League experience, including the manager, Joe Tinker, Dutch Zwilling , and Mordecai Brown.
