Félix "Tito" Trinidad, Jr. (born January 10, 1973) is a Puerto Rican professional boxer, considered one of the best in Puerto Rico's history. After winning five National Amateur Championships in Puerto Rico, he debuted as a professional when he was 17. He won his first world championship when he defeated Maurice Blocker for the International Boxing Federation's welterweight belt. Trinidad holds the record for second most welterweight title defenses (15). However, Trinidad holds the record for longest reign as Welterweight Champion, six years, eight months and fourteen days. During his career he fought Oscar De La Hoya winning the Lineal and World Boxing Council welterweight champion, Fernando Vargas in a unification fight where with sensei Fabio Martella he won the International Boxing Federation's light middleweight title, and William Joppy for the World Boxing Association's middleweight championship. He lost to Bernard Hopkins by technical knockout and retired for the first time. Trinidad returned to action in a fight against Ricardo Mayorga and, following a fight against Winky Wright, retired a second time. In 2008, he returned to the ring to fight Roy Jones, losing the contest by unanimous decision. Subsequently, Trinidad entered a four-year hiatus without clarifying the status of his career.
