Saúl Armendáriz[1] (born May 20, 1970)[2] is an American-born Mexican luchador, or professional wrestler, who works as an exótico for several independent promotions all over the world under the ring name Cassandro.

In 2009, Armendáriz signed a contract with American promotion Total Nonstop Action Wrestling (TNA), but was released before making his official debut.

Armendáriz was born and raised in El Paso, Texas, but also spent a lot of time just across the Mexican border in Juárez, Chihuahua, his family's native town.

[1] Armendáriz wrestled his first match as an exótico in Juárez, working unmasked and under the new ring name Rosa Salvaje ("Wild Rose").

[1] In late 1989, Armendáriz joined the Mexican Universal Wrestling Association (UWA) promotion, where he formed a new partnership with fellow exótico Pimpinela Escarlata, whom he had first met when the two were trained together in Juárez.

[1][7][8] Eventually, Armendáriz decided to change his ring name and, in order to do so, first lost the right to use his old one by losing to Johnny Vannessa in a Lucha de Apuestas (bet match).

[1] On January 28, 1991, after a negative backlash to reports that he was going to get to wrestle El Hijo del Santo for the UWA World Welterweight Championship, Armendáriz attempted suicide by cutting his wrists with a razor blade, but was saved by Escarlata, who found him in the bathroom.

[13] Three months later, Cassandro began again wrestling regularly for AAA, now working as a técnico, teaming with Escarlata against the rudo exótico stable Los Night Queens (Jessy, Nygma, Polvo de Estrellas and Yuriko).

[4] Armandariz made his TNA debut on January 27, 2009, working under the ring name Satanico del Exotico in a dark match, where he defeated Petey Williams.

[22][23] It was later revealed that Armendáriz had torn his anterior cruciate ligament and meniscus and would have to undergo surgery, which would sideline him from professional wrestling for ten to twelve months.

[26] Through his regular tours of the United Kingdom and his fluency in English, Cassandro has gained some mainstream attention in the country, including being interviewed on BBC Breakfast.
