A lot has been said about this matchup. Some experts say they believe it has fight of the year potential. Gary Shaw, who promotes Marquez, said this is the type of fight in which there will be no loser because it pits the best 118-pounder in the world against the best 122-pounder. One thing’s for sure: it will be the 77th world championship fight between two Mexican nationals.

You’re all set! Rafael Marquez has doled out a lot of pain over his terrific career, having knocked out 32 opponents while compiling a record of 36-3. He is 8-0 in world title fights. But that damage has been done in the bantamweight division. Marquez will move up in weight tonight to challenge Israel Vazquez for his World Boxing Council super bantamweight belt at Home Depot Center in Carson. When the opening bell rings, an all-out assault by the Mexican fighters is expected. “I am strong and I am a great fighter. So why should I feel that way?” Marquez won the International Boxing Federation bantamweight championship with an eighth-round technical knockout of Tim Austin in February 2003. He made seven successful defenses, five by knockout. Now, he not only is moving up to super bantamweight, he is taking on the best fighter in the world in that division. Thus all the questions about how he will fare at the higher weight. It seems to have been a theme at news conferences and conference calls promoting the fight. “It was my decision to move to 122, so I will be well-prepared,” Marquez said. He had better be, because Vazquez is coming to rumble. “He is going to have to deal with fighting me,” said Vazquez, who is 41-3 with 30 knockouts. “I am a natural 122-pounder. He has never had to do that before. So I think that will be the biggest obstacle or problem facing him.” So it won’t take long to ascertain whether Marquez brought his tremendous punching power up a weight class. “The four-pound difference does not do anything to me,” said Marquez, 31, of Mexico City. “I feel stronger, actually. I wanted to move up a long time ago. I do not feel any disadvantages moving up to 122.
