Middleweight contender Sergio Martinez (49-2-2, 28KOs) has no fear of WBC middleweight champion Julio Cesar Chavez Jr. (46-0-1, 32KOs) having a weight advantage on September 15th at the Thomas & Mack Center in Las Vegas.
Chavez, who always makes the middleweight limit, often bulks up to 180-pounds, or more, by the time he enters the ring. Martinez, who plans to use movement and speed, expects the extra mass to slow Chavez down and provide a much bigger target.
"He showed be worried about coming in twenty pounds heavier because it's going to give me a lot more to hit," Martinez told BoxingScene.com.
Martinez does admit that he will likely spar with fighters who are very similar to Chavez in size, which may include securing sparring partners from higher weight divisions.
While Martinez considers Chavez to be the biggest "name" opponent of his entire career, he doesn't believe the fight will be the most difficult. He says former champion Kelly Pavlik was the most difficult fight of his entire career, followed by the first fight with Paul Williams.
"I don't think that it will be the most difficult fight [of my career], but of course it will be a difficult fight. [The most difficult fight] for me was Kelly Pavlik and then Paul Williams, the first [one]," Martinez said.
