Instead, the mayors are using the competition as a way to help the homeless. A homeless social service agency in the winning city will receive $2,000 in corporate donations.
No matter who wins, the money will be given collectively by Citizens Bank, FirstBank in Denver and Philadelphia-based cable giant Comcast, which also operates in Colorado.
In Philadelphia, the money will go to Project HOME; in Colorado, it will go to Denver's Road Home.
The best-of-five series starts Wednesday afternoon at Citizens Bank Park in Philadelphia.
