David Diaz is the current WBC Lightweight Champion. David Diaz have won the interim title fight with Jose Armando Sta. Cruz. Joel Casamayor, the champion at that time, failed to make the required weight in this division in his fight with Diego Corrales. So that’s why the Lightweight Title was awarded to Diaz. Diaz have defeated the legendary Eric Morales last August 4, 2007 in his title defense. And recently, March 15,2008, he defeated Ramon Montano.
