Overweight and overconfidence were the factors that worked against former junior world champion Jason "Canito" Sosa, according to the boxer's trainer Raul "Chino" Rivas.
Rivas reveals that his boxer was not in the best possible condition to face Olympic gold medal winner Yuriorkis Gamboa and paid the price.
Last Saturday, Gamboa scored a controversial ten round majority decision with scores of 95-93, 96-92 and 94-94 - despite the fact that he visited the canvas and was penalized a point for excessive holding.
For Sosa it was his second consecutive defeat. Last March, he lost to Vasyl Lomachenko when they fought for the World Boxing Organization (WBO) belt.
Rivas stressed that Sosa did not make the adjustments to counter Gamboa.
The fight was agreed upon at 131 pounds. While Gamboa made 130.6 pounds, Sosa could not make the weight and came in 131.2 pounds.
"The time that Jason spent in Puerto Rico he was working with business that he opened up and that killed us. He arrived at 164 pounds to start training. Never in my life had that happened," Rivas told Carlos Gonzalez.
"In my heart I feel happy because I understand that we won that fight. But that was 50 percent of what Jason Sosa can do. I think his mentality was not in the training, not in the fight. I hope he has learned.
"For some reason he was throwing the overhand right when Gamboa is not tall. He did not use the uppercut and the hooks on the inside. The chemistry was not there. He just did not listen to the advice."
On the other hand, Rivas said executives at HBO expressed interest in Sosa returning to the ring as early as April 2018.
"I told Jason that he needs to be at least a month away from the gym [and then back in]. I understand that he will go to Puerto Rico to continue attending the businesses that has and then we will talk about the next thing," Rivas said.
