Lopez should have won his last big fight, not long ago on an undercard. He is currently trained by the same people that train Chris Arreola, out of Riverside. His original trainer, he died a few years back, was a very good guy. I had the pleasure of meeting him on several occassions.
Lopez is noramlly a very aggressive and hard punching fighter; when I saw him last, in2006, he was punching very hard. In his last fight, that I am aware of, he lost to a GBP fighter on a GBP card. I thought he won, be he waited too much. He could've and should've ended the fight.
Ortiz is there to be hit and Lopez used to be a pretty big puncher. He is probably 30 now, which makes me feel old, but he should be a pretty live opponent. If he comes to win there is no reason why he shouldn't.
