CMLL Universal Championship (2013)
The CMLL Universal Championship 2013 was a professional wrestling tournament produced by the Consejo Mundial de Lucha Libre promotion, which took place over three shows between August 23 and September 6, 2013, in Arena México, Mexico City, Mexico. The CMLL Universal Championship is an annual tournament of CMLL champions that was first held in 2009.
Background
The tournament featured 15 professional wrestling matches under single-elimination tournament rules, which means that wrestlers were eliminated when they lose a match. There were no specific storylines that build to the tournament, which has been held annually since 2009. All male "non-regional" CMLL champions at the time of the tournament were involved in the tournament with the exception of the reigning CMLL World Mini-Estrella and Mexican National Lightweight Champions, who have never taken part in the tournament. Regionally promoted championships such as the CMLL Arena Coliseo Tag Team Championship and the Occidente championships promoted in Guadalajara, Jalisco were not included in the tournament; only titles that have been defended in CMLL's main venue Arena Mexico were included. The tournament was divided into two qualifying blocks, which took place on August 23 and August 30, while the final took place on September 6, 2013.2013 Universal Championship tournament
