The winner of the tournament will be awarded CONMEBOL's spot in the 2017 FIFA Confederations Cup.
Mexico has already been named to the following year's 2016 Copa America Centenario, joining host USA as the automatic CONCACAF entrants. Jamaica could also qualify for that tournament through the 2014 Caribbean Cup or the 2015 Gold Cup.
