Diaz pressed ahead, but Morales countered very effectively landing sharp and clean punches. Diaz right eye was swelling badly by the end of round six, but Diaz had a very good round seven pounding Morales on the ropes. Diaz was relentless as he bulled Morales into the ropes again the eighth. Morales spent most of the ninth in the center of the ring and had good results in the twnth and eleventh. Diaz went all out in the twelfth round, applying tremendous pressure. In the end, scores were 114-113, 115-112, 115-113, all for Diaz.
