Juan Diaz started boxing when he was eight-years-old at Willie Savannah’s Boxing Club in Houston, Texas. In December 1999, he won a gold medal at the Mexican Open National Championships and was declared the “Outstanding Boxer” of the tournament. He thought he had qualified for the 2000 Mexican Olympic team but was later informed that he was too young to compete at the Olympics. Diaz considered staying an amateur and trying to make the 2004 Olympic team, but he eventually decided to turn professional. He finished his amateur career with a record of 105-5.
On July 17, 2004, Diaz defeated Mongolian Lakva Sim by a twelve-round unanimous decision to win the WBA lightweight title. After five successful title defenses, Diaz engaged in a unification fight. On April 28, 2007, he defeated WBO titlist Acelino Freitas by an eighth-round TKO to unify the WBA and WBO lightweight titles. Diaz was then upgraded to super champion by the WBA. In his next fight, Diaz took part in another unification match. On October 13, 2007, he beat Julio Diaz by a ninth-round TKO to win the IBF lightweight title.
Diaz lost his lightweight titles to Nate Campbell by a twelve-round split decision on March 8, 2008. It was his first defeat after 33 consecutive professional victories. Diaz fought Juan Manuel Marquez for the vacant WBO lightweight title and the vacant WBA super world lightweight title on February 28, 2009. Marquez won by a ninth-round TKO. The fight was named the 2009 fight of the year by both The Ring and the Boxing Writers Association of America.
On June 13th 2011, Diaz officially announced his retirement. He returned to the ring on April 13, 2013, stopping journeyman Pipino Cuevas Jr. in six rounds.
