"I've never been cut, never been stopped and Nonito Donaire - I'm coming to win by knockout or by points," Hernan "Tyson" Marquez said bluntly, as he trains in Mexico City to fight for the super flyweight interim title of the World Boxing Association (WBA) held by Donaire of the Philippines. The fight happens on July 10 on the island of Puerto Rico.

"I'm well of Nonoto's abilities. I respect him, but I'm getting ready to fight for fifteen rounds which he won't be able to withstand, said Marquez, who trains under the orders of his manager Rudy Perez and Jesus Lucero, who is responsible for the conditioning.

The Tyson has already put about 70 rounds of sparring partners:

"Donaire is a fast fighter, strong, but I have studied him well. Moving around, coming in in with speed and punishing the body and jaw, I'm going to win," said Marquez, who is 21 years old and sports a record of 27 fights, and one loss with 20 knockouts in his favor.

“The most important thing is to stop him from move around so much. He does not have much resistance. If you touch his jaw, he starts to move around in bad shape. He has a glass jaw," said Marquez.
