The Territorial Cup Series (also known as the Duel in the Desert Series) is the yearlong rivalry competition between the University of Arizona Wildcats (U of A) and the Arizona State University Sun Devils (ASU). The series first started in 2009 and State Farm was the original sponsor until 2012 (both universities are currently seeking new sponsorship). Although without an official sponsor, media outlets and both universities continue to track and promote the series records.
