By Jason Kim: 38-year-old two-time WBC lightweight champion Jose Luis Castillo (63-11-1, 54 KO’s) has reportedly signed a new promotional deal with Blue Wave Boxing, the same promotional company that WBA World super bantamweight champion Guillermo Rigondeaux fights under.

Castillo now fights at welterweight and has lost two out of his last five fights since 2010. He was supposed to fight last week on the undercard of the Erik Morales vs. Danny Garcia fight in Houston, Texas against Jose Miguel Cotto, the older brother of WBA junior middleweight champion Miguel Cotto. However, Castillo pulled out of the fight after failing to make weight.

Castillo has to be able to make the 147 pound welterweight limit because at 5’8″ with a small frame, he’d be at a huge disadvantage if he were forced to move up to 154 just to make weight. There are some real beats in that division that would likely tear Castillo apart.

Castillo was stopped in the 6th round by Alfonso Gomez in March of 2010. Last year, Castillo was beaten by Jorge Paez Jr. by a 12 round unanimous decision.

In two memorable fights with Floyd Mayweather Jr., Castillo fought him tough enough to where a lot of boxing fans though that Castillo deserved a 12 round decision win in his first fight with Mayweather in April 2002. Castillo would go on to defeat a prime Joel Casamayor, Saul Duran, Julio Diaz and Diego Collales. Castillo was beaten by Corrales by a 10th round TKO in their first fight in May 2005, but came back to stop Corrles in the 4th round five months later in October 2005. Those two fights were kind of the end of the road for Castillo in terms of finding big success, as he was beaten two years later by Ricky Hatton by a 4th round knockout in a light welterweight bout. Castillo was beaten again this time by Sebastian Lujan by a 10 round unanimous decision at welterweight in July 2008.
