Édgar Sosa, born on August 23, 1979, in Mexico City, Mexico, is a renowned figure in the world of boxing. His professional career, which spanned over two decades, was marked by resilience, determination, and a penchant for thrilling performances. Sosa made his professional debut on April 1, 2000, at the iconic Arena Mexico in Mexico City, where he secured a points victory over Cesar Gonzalez in a four-round bout.
Sosa's amateur background is not extensively documented, but his professional journey is replete with notable achievements. He rose to prominence by winning the WBC Light Flyweight Championship on April 14, 2007, defeating Brian Viloria via a majority decision. This victory marked the beginning of a successful title reign, during which he made ten title defences. His reign was highlighted by victories over formidable opponents like Roberto Carlos Leyva and Juanito Rubillar. However, his title tenure was marred by a controversial loss to Rodel Mayol on November 21, 2009. Sosa suffered a severe injury from a headbutt, leading to a stoppage loss and a subsequent protest to the WBC, which eventually declared him a "champion emeritus."
Throughout his career, Sosa faced a plethora of world-class fighters. His bouts against the likes of Luis Alberto Lazarte, Sonny Boy Jaro, and Pongsaklek Wonjongkam showcased his ability to compete at the highest level. Despite setbacks, including losses to Ulises Solís and Donnie Nietes, Sosa consistently demonstrated his resilience and skill. His later years saw him move up in weight, competing in the flyweight and super flyweight divisions, where he encountered fighters like Roman González. Sosa's final professional outing was on December 15, 2023, against Juan Carrera Martinez, which he won via technical knockout in the fourth round of a scheduled six-round bout. This victory capped off a remarkable career that included 53 wins, 31 by knockout, and 11 losses.
Sosa's legacy in boxing is underscored by periods of dominance, particularly during his title reign, and periods of struggle, including his early losses and the controversial defeat to Mayol. Despite these challenges, he remains highly respected as one of the best lower-weight boxers of his era.
