WFTDA Western Regional Tournament
The Tournament was organised by the Women's Flat Track Derby Association (WFTDA). Full WFTDA members in the Western Region members were eligible for ranking, and the top ten leagues would qualify for the Western Regional Tournament, with the top three finalists qualifyinh for the Championships. Together, the four qualifying tournaments and Championships were termed the "Big 5". Starting with the 2013 WFTDA season, WFTDA's regions were discontinued in favor of an overall-rankings based system, and a new playoff format was created.
