By Dan Ambrose: On September 15th, WBC middleweight champion Julio Cesar Chavez Jr. (46-0, 32 KO’s) and Sergio Martinez (49-2-2, 28 KO’s) will be taking part in what will easily be the best fight at middleweight since Martinez took on Kelly Pavlik.

It’s no secret that Chavez Jr. will be planning to take the fight to the inside so that he can work over the body of the much smaller Martinez. However, Martinez isn’t going to be just standing there making it easy for Chavez Jr. in this fight and will stay on the move because he knows that Chavez Jr’s only chance of winning this fight is if Martinez stations himself against the ropes or just stands in the center of the ring without moving like most of Chavez Jr’s opponents have foolishly done against him.

Chavez Jr. said this as quoted by the bostonherald.com “My trademark now is the body punching. In this fight it’s going to be key. When he fought his last fight, his cup was lifted up almost to his chest. So I know he’s going to try to protect himself.”

Chavez Jr. has spent virtually all of his career trying to emulate the fighting style of his famous father Julio Cesar Chavez Sr. You can see Chavez Jr’s father’s style in almost everything that the 6’1″ Chavez Jr. does in the ring with body punching and high pressure style of fighting.

Despite being much bigger than his 5’7 1/2″ father, Chavez Jr. has been slow in changing his inside fighting style. Tall for a middleweight, Chavez Jr. generally gives his weight and willingly fights on the inside against his shorter opponents. Normally this would be a recipe for disaster, but Chavez Jr. has had several things going for him since he started facing better opposition last year: Chavez Jr’s weight is usually much more than his opponent giving him often a 15 pound weight advantage. That’s a considerable amount when you’re talking about middleweights. If Chavez Jr. were a heavyweight it wouldn’t be as big of a deal him weighing 15 to 20 pounds more than his opponent. Chavez Jr’s body punching is formidable when he can get his shots off. Those punches are hard to take because he’s skilled at throwing them and he’s got all that weight behind him. Since the WBC doesn’t have rehydration weigh-in limits, Chavez Jr. can march into his fights weighing as much as a cruiserweight and that definitely helps with his body punching. Chavez Jr. also has a great ability to take head shots. Part of that obviously is him weighing so much more than his opponents. But he definitely can take a big shot. Whether that will stay the same once Chavez Jr. can no longer make 160 has to fight guys that will rehydrate up to the same amount as him at super middleweight, light heavyweight or cruiserweight, that’s the big question.
