You are spot on with the crowd lifting Lazarte to heights he couldn't achieve normally. I also think the frenzy of the crowd (they were NUTS) made it difficult for the referee and the judges. Every punch Lazarte threw (legal or illegal), every grab and hold, every headbutt. It didn't matter. They LOVED it in Argentina. And Tamara played RIGHT INTO IT.
Tamara most certainly had a letdown and I just wish I had anticipated this. I was VERY influenced by the opponent's age, the weigh-in photo, and the article on boxingscene which described the "easy" optional defense. Not so easy, it turns out.

This fight was VERY similar, in fact, to the Cruz-Solis fight. A dirty, foulfest with the local crowd going crazy for their guy - a win by any means necessary.
I read today that Lazarte is as street sweeper by profession in Argentina, and a beloved figure. It was sort of funny, in the article, how they listed all his DQ losses. The guy has been DQ'ed 4 times and it is VERY clear why. He deserved several point deductions last night, but it was never going to happen.
In a fairly judged fight I can't see Lazarte winning. But honestly I stopped judging after about rnd 8. The writing was on the wall. I could see what the script was in Argentina - and I was pulling my hair out for laying the price.
Got bit this week - it happens.
