Kelson Carlos Santos Pinto (born November 26, 1976 in Aracajú, Sergipe) is a Brazilian boxer, best known to win the silver medal at the 1999 Pan American Games in Winnipeg, Canada.

He represented his native country in the light welterweight division at the 2000 Summer Olympics in Sydney, Australia. There he was eliminated in the second round by Uzbekistan's eventual gold medalist Mahammatkodir Abdoollayev.

Santos Pinto turned pro in 2000 and remained undefeated until fighting Miguel Cotto (which he had defeated as an amateur) for the WBO junior welter title, where he lost by KO in 2004. In 2005 he lost to veteran Vince Phillips.

Miguel Ángel Cotto (born on October 29, 1980) is a Puerto Rican professional boxer. Cotto is a former WBA (Super) Light Middleweight Champion. He is the younger brother of contender Jose Miguel Cotto and cousin of Abner Cotto and Carlos Cotto. He is a four-time world champion in three weight divisions (light welterweight, welterweight and light middleweight).

On September 11, 2004, Cotto faced Kelson Pinto from Brazil, for the vacant WBO Light Welterweight title. This represented the third fight between them, with Pinto being victorious in their two previous encounters, both of which took place while they were still amateurs. Many fight fans feel this was due to the training from Edward Bemis in Puerto Rico. The fight was televised by HBO from San Juan, Puerto Rico. During this card, Cotto utilized a defensive stance with his hands in a high position instead of his usual aggressive orthodox stance. Over the course of the fight Cotto scored three knockdowns and won the fight by knockout in the sixth round.

Emanuel Augustus (previously known as Emanuel Ya'kov Burton) (born 1975 in Chicago, Illinois) is a professional boxer. He fights out of Brownsville, Texas

Originally from Chicago, Illinois, Augustus grew up in Louisiana and boxed out of Baton Rouge, Louisiana. He currently resides in Brownsville, Texas, and boxed at Grechy's Pound 4 Pound Gym located in Sydney, Australia for a brief period of time.

Augustus began his boxing career under his birth name Emanuel Burton. However, in 2001, when his parents married, Burton adopted his father's last name of Augustus. He retained the nickname "YA", short for his middle name Ya'Kov. Emanuel has frequently appeared on ESPN2's boxing programs Tuesday Night Fights and its counterpart Friday Night Fights. He achieved a measure of fame after his bout against Courtney Burton on July 6, 2004, which he lost by an extremely controversial decision. The state of Michigan investigated the verdict but did not overturn it. Augustus avenged that loss September 1, 2006, when he stopped Burton in the 8th round on ESPN.
