Sergio Martinez wants to knock out Julio Cesar Chavez Jr. in the worst way when they collide at the Thomas & Mack Arena this Saturday evening, and the World Boxing Council middleweight belt on the line. There?s no getting around that these two chaps simply don?t like each other, and because they don?t, it?s shaping up to be one of the best bouts of the year. Chavez has a few advantages like having trainer Freddie Roach in his corner, height (two inches), staying power, and his father, Julio Cesar Chavez, the greatest Mexican boxer ever, will be ringside. Now, will all this matter when the bell tolls for the combatants to touch gloves? Martinez (49-2-2 with 28 knockouts) isn?t fighting for just himself, but will be battling for millions of fans back in his native Argentina. You see, he?s going to bring back the ghost of Carlos Monzon, Argentina?s man of steel. Martinez, a left-hander, is a devastating puncher good enough to floor an opponent with one blow, so Chavez (46-0-1 with 32 KO?s) will be cautious. Neither will shy away, but in the end, Martinez, the favorite, will reign supreme and drop his foe with a ninth round knockout. BY Pietro Baio Sept 15, 2012 is a big day for boxing. The middle weight championship of the world will be decided between Mr legacy , Julio Cesar Chavez jr and Mr Maravilla, Sergio Martinez. Which is the real champion at 2012? While Chavez has shown increase in strength and skills I don?t know if he has what it takes to beat ?Maravilla?. Sergio has shown he is a fan friendly fighter. He has beaten some of the best at 154 and 160, yet still doesn?t get much respect or recognition for his wins over Pavlik and Williams. Come Sept 15, Sergio will use his angles, speed and stamina to beat the young lion and quiet doubters once and for all.
