While Rube Foster continued to run the Leland Giants Baseball Club, Leland started a new corporation in October 1909 called "Leland's Chicago Giants Baseball Club" or, in short "Chicago Giants" opening his offices at 2551 State Street in Chicago.
The confusion over the Leland name amongst the teams changed as Rube Foster changed the Leland Giants name to the Chicago American Giants, and Leland's team became the Chicago Giants.
