Trainer Freddie Roach said today that Julio Cesar Chavez Jr is a ‘quick learner and is going to be a more complete fighter. “He’s shy about his English, but understands everything I say,” Roach said today. “Chavez Jr is a quick learner. I teach and he picks it up real quick. We’re working on his jab, to throw it and set something up after throwing it. He’s getting a real idea of what I would like him to do. “He works hard, likes to run, knows the game,” Roach said. “Duddy is trouble because he is so strong. I think Chavez Jr has more boxing skill and that will be the difference on Saturday night.” Chavez Jr vs. Duddy is scheduled for Top Rank’s Latin Fury 15 on Saturday, June 26, at the Alamodome. The Pay Per View will begin 10 pm eastern/7 pm pacific.
