 The Illinois teams are Moline, United Township (of East Moline), Rock Island, Rock Island Alleman, and Galesburg, all representing the Western Big 6 Conference; the other participating teams are Geneseo and Riverdale of Port Byron, Illinois.No champion is crowned, although matchups are generally determined based on pre-season polls and past successes of the competing teams, with the two teams believed to be the "best" in the pre-season polls playing in the last game of the day.A similar seven-game shootout competition for the girls takes place in January at Wharton Field House in Moline; the same six MAC schools compete against the metro Western Big Six schools, plus Geneseo and other schools from western Illinois.
