Santa Cruz won 11 rounds against Casamayor who was number 1 lightweight.
And David Diaz knocked the **** out of Cruz.
So he is number 1.
TOUCHE HATERS!
and then David Diaz was supposed to have defended that Lighweight agianst Humberto Soto on the Pacquiao-Marquez II undercard, but Pac got scared nad had Arum replace Soto with Roman Montano, that way Diaz beats Montano and is preserved for Pac to fight for the WBC Lighweight title, so long, David Diaz has it, and not Soto, cause Pac is so damm scared to fight Soto, that he jumped weight divisions each time Soto moved up to challenge him.
