WBO strawweight champion Ivan Calderon (29-0, 6 KOs) moved up to the 108lb division to dethrone WBO mini-flyweight champion Hugo Cazares (25-4-1, 19 KOs) via twelve round split decision on Saturday night at the Coliseo Ruben Rodriguez in Bayamon, Puerto Rico. For the first seven rounds hometown favorite Calderon put on a boxing clinic, landing clean shots while avoiding Cazares' punches. Cazares finally got to Calderon and dropped him in round eight. Calderon spent round nine holding and running, but frustrated the attacks of Cazares over the last few rounds to win by scores of 115-112, 115-112 on two cards. Cazares was ahead 116-111 on the third card.
