By Jason Kim: Sampson Lewkowicz, the adviser for WBC Diamond middleweight champion Sergio Martinez (49-2-2, 28 KO’s), says that a fight between the 37-year-old Martinez and Chavez Jr. is completed for September 15th in a fight that will take place at the Thomas & Mack Center, in Las Vegas, Nevada.

Lewkowicz said on his twitter today “I have received a call from Lou Dibella confirming Chavez Jr-Martinez is a done deal.”

Chavez Jr. will finally get the chance to prove if he truly belongs in the top 5 in the middleweight division if he can beat Martinez. Right now, Chavez Jr. is still considered a fringe player because of his mostly weak opposition he’s beaten during his 9-year career. Last night, Chavez Jr. took a small step forward with a 7th round TKO win over (28-2, 20 KO’) at the Sun Bowl in El Paso, Texas.

However, the win wasn’t as big of a deal as Chavez Jr. and his management would have you believe, because Lee had already been stopped by 2nd tier fighter Brian Vera in the past, and almost beaten by the light hitting fringe contender Craig McEwan last year. Lee always could punch a little, but he his chin, stamina, inability to handle pressure and lack of an inside game were always going to hold him back when it came time for him to try and get to the next level.

The things that Chavez Jr. did with Lee last night are things that have already been done with him. Chavez Jr. has to prove that he can beat a fighter that can really punch, can move and who has a better chin. Chavez Jr. didn’t throw a lot of punches last night and he didn’t look all that fast. Martinez would be a much more difficult opponent because he wouldn’t have sat on the ropes letting Chavez Jr. tee off like he last night. Lee’s trainer Emanuel Steward was practically begging him to stop slugging with Chavez Jr. and focus more on boxing. He also told him to stay off the ropes, which Lee promptly ignored.

I’m sure he regrets not listening to Steward now, but that’s his lesson. Martinez wouldn’t have to be told these things, because he’s not going to fight Chavez Jr’s fight by standing in close and letting him fight an inside bout, and he’s not going to work off the ropes like Lee did.

Martinez will use movement to befuddle Chavez Jr. and punish him with huge left hands to the head. I see this fight going badly for Chavez Jr. with him either getting knocked out or badly beaten up. It’s good that the fight will be held in Las Vegas, because I’d hate to see Martinez in a position where he might need to knock Chavez Jr. out in order to win in Texas.
