Carlos Maussa

The bout was notable for a number of reasons: Harris was an overwhelming favorite and is regarded as one of the best boxers at the weight and Maussa’s awkwardly clever style and frequent clowning gestures and facial expressions lent him an air of amateurishness. At the beginning of the seventh round Maussa delivered a stunning left hook, KO-ing Harris. Maussa then lunged downward and punched him in the head while he was already supine on the canvas. The ropes absorbed the impact of the blow. Still, this act has led to much controversy, as the hit could have disqualified Maussa. After the match, however, the bout referees ruled that the late hit was “insignificant”, allowing Maussa to keep his title. When interviewed about this punch, Maussa claimed he didn't connect with Harris on purpose, and that his sole intention was to impress the fallen Harris in case he had any desire to fight on.

Maussa began his career with twelve victories in his native Colombia before coming to the United States. He then won four bouts in the U.S. before facing highly touted New York prospect Jeffrey Resto, described as "perhaps the most-talked-about young pro in New York". In this battle of two undefeated fighters (17-0 Resto vs. 16-0 Maussa), Resto was unable to deal with Maussa's unorthodox fighting style and abruptly quit in the 6th round, earning Maussa an unexpected victory. Both fighters' careers ended half a decade later with a loss to the same fighter, Victor Ortiz.

Maussa's win over Resto earned him a shot at fellow 17-0 boxer and WBC International light welterweight titleholder Miguel Angel Cotto. Maussa's fight against Cotto was less successful, resulting in Cotto winning by an 8th round TKO. Following this, Maussa fought in three lower-profile fights, winning two. Then, on 25 June 2005, he entered the popular consciousness of boxing fans with an upset win by KO against WBA light-welterweight titlist Vivian Harris. This exciting victory made Maussa a new champion in one of boxing’s competitive divisions.

The victory cemented Maussa's reputation as somewhat of a gatekeeper for up-and-coming light welterweight prospects, but ended up being his last victory. On 26 November 2005 Maussa lost his WBA title against IBF title-holder, Ricky Hatton, in a unification bout. After a unanimous decision loss to Manuel Guarnica, Maussa fought well-regarded future titleholder Victor Ortiz, and was knocked out in the first round. Following this, Maussa retired with a professional record of 20 wins and 5 losses in a total of 113 professional rounds of boxing.

Turning pro in 2000, at the age of 29, Maussa won two titles and fought in several significant fights until his retirement at age 38.
