Born on July 17, 1983 in Santa Fe, Argentina, Marcos Maidana is the current World Boxing Association Interim Super Lightweight champion. He has only been defeated twice in his professional career, to Andreas Kotelnik and Amir Khan. He has also won the WBA Fedelatin Light Welterweight.
Maidana enjoyed a successful boxing career as an amateur. He was the Argentine National Champion for 2002 and 2003. In 2003, Maidana was the Quarter-finalist at the World Championships in Bangkok, Thailand. He also had the opportunity to compete in the 2004 Olympics but missed when he lost the last Olympic qualifier in the semi-final in Rio de Janeiro, Brazil.
The 27-year old was defeated by Kotelnik in 2009. The judges gave the title to Kotelnik via a split decision, despite the heavy damage he had inflicted on Kotelnik’s face. He then fought Victor Ortiz at the Staples Center in LA before defeating William Gonzalez at the Hard Rock Hotel and Casino. His next fight was against Victor Manuel Cayo, who was then undefeated. Kotelnik defeated Cayo in the sixth round, successfully defending his interim WBA super lightweight title.
He staged another successful defense of his WBA Light Welterweight world title against DeMarcus Corley in 2010 at the Estadio Luna Park, Buenos Aires, winning the match by unanimous decision. This win was followed by his second professional loss, to Amir Khan at the Mandalay Bay Resort in the fight dubbed as the Fight of the Year by the Boxing Writers Association. He made up for this loss by defeating Eric Morales on April 9, 2011 at the MGM Grand Arena.
Currently Maidana boasts of 31 fights won, 28 via knockout and 2 losses. For 2011 alone, Maidana had 2 victories, Morales in April and Petrov in September.
