Ben Davison, the head trainer of heavyweight Tyson Fury, saw several errors in Anthony Joshua's shocking defeat to Andy Ruiz.
Ruiz pulled off a huge upset when he stopped Joshua in seven rounds on June 1 at Madison Square Garden in New York City, to capture the WBA, WBO, IBF, IBO heavyweight titles.
Joshua, a very wide favorite to win the fight by knockout, was dropped four times before a shocked crowd.
Davison explained where things went wrong for Joshua and why he wasn't able to neutralize Ruiz.
"When you go to a gym there’s a textbook telling you how to box – you step in with your jab, you do this, you do that," Davison told iFL TV.
"That’s why those things are going to happen, at that level textbook boxing isn’t going to win it for you. Boxing a small man like Ruiz, who has to be planted to let his shots go to have the same effect if he was travelling while he was punching.
"If he’s planting with his feet he’s got fast hands, good variety and he can punch, so Joshua needs to understand how to create distance, maintain distance at different distances, and understand different distances. When you’re boxing someone like that, when you step in with your jab you’re closing the distance for that man, a textbook says step in with your jab.
"But if you miss that jab you’ve closed the distance for the short man to let his well-varied punches go, with speed and with power. When that jab is not landing, then you reach with a right hand, which 10 times out of 10 for Joshua he’s going to come back with a left hook, then after the left hook he’s going to come back with a right uppercut then a left hook. I noticed he tried to throw a jab from the hip, I’ve never, ever seen him in training throw a hip jab. I feel like he’s been getting caught in between those two styles, and there are a lot of technical things I can see that needs to be picked up on."
