The Leyenda de Plata (Spanish for "the Silver Legend") is an annual lucha libretournament held by the Mexicanprofessional wrestling promotionConsejo Mundial de Lucha Libre (CMLL) since 1998. The tournament honors El Santo, Enmáscarado de Plata (the Silver mask) and has been held every year since 1998 except for 2003 when El Hijo del Santo (El Santo's son) did not work for CMLL. CMLL still holds the annual tournament despite El Hijo del Santo no longer works for CMLL. It is the most prestigious of all of CMLL's annual tournaments. The original format of the tournament was the Torneo cibernetico to qualify for a semi-final. The winner of the semi-final faces the winner of the previous year's tournament in the final. Since 2005 CMLL has held two cibernetico matches and the winner of each then meet in the semi-final. In 2011, the tournament was modified to eliminate the final stage. The winner is given a plaque with a solid silver El Santo mask on it. Only two wrestlers have won Leyend de Plata more than once, Místico won it in 2006, 2007 and 2008 and Negro Casas in 2000, 2014 and 2015. After a two year hiatus, the tournament returned in 2011.
After not holding a Leyenda de Plata tournament in 2003, it returned in 2004 with the qualifying cibernetico being held on July 16, 2004. the teams were: "A", Alan Stone, Atlantis, Averno, Mephisto, Misterioso, Jr., Satánico, Tarzan Boy and Virus. Team "B", Black Warrior, Perro Aguayo, Jr., Emilio Charles, Jr., Másacara Mágica, Místico, Negro Casas, Super Crazy and Volador, Jr.. The main storyline of the cibernetico was the building rivalry between Negro Casas and the recently rudo-turned Perro Aguayo, Jr. Aguayo cheated to eliminate Negro Casas and along with Atlantis were the last two surviving wrestlers. On July 23, 2004 Aguayo and Atlantis wrestled in a singles match, which unlike previous years was a "best of three falls" match, that actually went to four falls before Perro Aguayo, Jr. won. A week later Perro Aguayo, Jr. defeated El Felino, using the victory to further the storyline with Negro Casas, Felino's brother and corner-man for the night. Following his victory Perro Aguayo, Jr. broke the plaque with El Santo's mask on it, claiming that the Aguayo's were the greatest family in wrestling, refusing to accept a trophy with El Santo's name on it.
The 2005 Leyenda de Plata is the only tournament to not feature the previous year's champion defending the trophy, playing off Aguayo's breaking of the trophy the previous year. The lack of defending champion forced CMLL to change the format of the Leyenda de Plata as they held two eight-man ciberneticos instead of one 16-man, with the winner of each cibernetico facing each other the following week. The two cibernetico format has been the standard tournament format for the Leyenda de Plata ever since 2005. The first cibernetico took place on October 28, 2005 and featured El Hijo del Santo, Hombre Sin Nombre, La Máscara, Volador, Jr., Misterioso, Jr., Jado, Averno and Negro Casas. The match came down to Hijo del Santo and Casas and initially ended in a double pin. After the match was restarted El Hijo del Santo won by submission. The second cibernetico took place on November 4 and saw Atlantis outlast a field that also included Místico, Último Dragón, Máxmio, El Sagrado, Mephisto, Hijo de Pierroth and Gedo. On November 11, 2005, Atlantis defeated El Hijo del Santo with help from his corner-man Último Guerrero to win the seventh Leyenda de Plata.
The 2006 Leyenda de Plata started on August 25, 2006 with the first of two eight-man cibernetico qualifying matches. The cibernetico saw Black Warrior eliminate Rey Bucanero as the last man in a match that also included Heavy Metal, Metro II, La Máscara, Último Guerrero, Mephisto and Misterioso, Jr.. With Black Warrior winning the first cibernetico it was not too surprising that Místico won the second cibernetico as the two had been involved with a long-running storyline feud throughout 2006. Místico outlasted Mr. Águila, Negro Casas, El Sagrado, Volador, Jr., Averno and Alex Koslov. The semi-final on September 8, 2006, saw Místico defeat Black Warrior, followed by a "mask vs. mask", Luchas de Apuesta challenge from Black Warrior that Místico accepted for the CMLL 73rd Anniversary Show. On September 15, 2006 Místico defeated Atlantis to win the Leyeda de Plata, overcoming interference from Atlantis' corner-man Black Warrior. After the match Black Warrior stole the Leyenda de Plata trophy and ran off with it, furthering their feud.
The ninth Leyenda de Plata was held between May 18 and June 8, 2007. This was the first year that Leyenda de Plata was held without El Hijo del Santo working for CMLL, CMLL claimed that they owned the rights to promote the Leyenda de Plata and has promoted it without Hijo del Santo working for CMLL since then. The first Cibernetico took place on May 18, Perro Aguayo, Jr. was originally scheduled to be part of the match, hinting at a very anticipated Aguayo vs. Místico match that had been building for a while. In the weeks leading up to the first cibernetico Perro Aguayo, Jr. was injured and had to pull out of the match, he was replaced by fellow Los Perros del Mal member Mr. Águila, who'd go on to win the qualifier over Negro Casas, El Felino, Tarzan Boy, Mephisto, Máximo, Alex Koslov, Stuka, Jr., Volador, Jr. and Mictlán. On May 25, 2007 El Sagrado qualified for his first ever Leyenda semi-final as he outlasted Averno, Ephesto, virus, El Texano, Jr., Leono, Loco Max, Valiente, Heavy Metal and BlacK Warrior. On June 1, 2007 Mr. Águila defeated El Sagrado to earn a spot in the final. On June 8, 2007 Místico became the first wrestler to not only win the tournament twice but also in back to back years as he defeated Mr. Águila. Following his victory Perro Aguayo, Jr. attacked Místico furthering the storyline between the top tecnico and top rudo of the promotion.
After a two-year hiatus the Leyenda de Plata tournament returned in late 2013 with two qualifying Torneo ciberneticos and a final match between each elimination match winner. The first match took place on December 20, 2013, as part of CMLL's Super Viernes show and was won by Titán. The second torneo was won by Negro Casas a week later. On January 3, Casas defeated Titán to win the tournament.
