Professional career of casamayor

He won the NABF Super Featheweight title in 1999. Later that year, he won the WBA Super Featherweight title. In 2002, he lost that title in a unification bout with WBO champion Acelino Freitas. In 2004, Diego Corrales, whom Casamayor stopped in 2003, defeated him for the vacant WBO Super Featherweight title. Casamayor failed to take the WBC Lightweight title from José Luis Castillo later that year. After the loss to Castillo Casamayor's career appeared to be in a downward spiral and he was set up with rising prospect Almazbek Raiymkulov in June of 2005. In a spirited battle the bout ended in a draw, with many believing that Casamayor's best days were behind him. After two bouts against little known opposition, in October of 2006, Casamayor yet again took on the popular Diego Corrales, and defeated him by split decision, winning the WBC Lightweight title.
