It's pretty good. Juan Manuel Lopez vs. Sergio Medina, 12 rounds, for Lopez's WBO junior featherweight title Victor Ortiz vs. Jeff Resto, 12 rounds, junior welterweights I'll be watching this card and these will be entertaining fights. I guess when you have a circus act like this, the undercard can be the selling point.
Medina is Argentinian. He is the guy whom Bautista defeated in a competitive fight for 12 rounds.. I think Lopez will take this guy out within 5.
It is to an extent but I think it really does nothing for each fighter's legacies. DLH is picking on the drastically smaller fighter and Pac has to jump a few weight classes to fight him.
That's a below average undercard. Pretty good would be something like matching up Lopez and Resto with top 10 fighters in their weight class. You can already chalk up wins for the two based on those opponents. Medina is an average fighter with no pop, a padded record, and who was clearly defeated by Bautista. Resto has been a C level fighter for his entire career.
