BEIJING • Dan Campbell spoke, and Luis Yanez didn’t listen.What better way to end a dysfunctional relationship between the steadfast U.S. boxing coach and the defiant Olympic Training Center resident?

Yanez executed a different strategy than Campbell ordered Saturday in a stunning 8-7 loss to Mongolian Serdamba Purevdorj in the second round of the 106-pound light-flyweight division at the Beijing Games.

The sixth American defeat, coming after middleweight Shawn Estrada dropped an 11-5 decision to Great Britain’s James DeGale, leaves the OTC-based team with welterweight Demetrius Andrade and heavyweight Deontay Wilder, who fight in today’s quarterfinals.

It also marks probably the final interaction between Campbell and Yanez, suspended by USA Boxing in July for skipping several weeks of an OTC camp to return to his Dallas-area home, then reinstated later that month when he issued a public apology.

“He basically did the opposite of what we asked,” said Campbell, the brains behind the residency program that has ruffled feathers because boxers must abandon their friends and families to train in Colorado Springs and can’t have access to their personal coaches.

Before the fight and after each round, Campbell claims he told Yanez, 19, he needed to attack Purevdorj, a little-known boxer who placed 33rd at the 2007 world championships, 28 spots behind Yanez.

Instead, Yanez fought passive, hardly throwing punches in the first round, won 3-2 by Purevdorj. More of the same followed in the second, as Yanez rarely unloaded his explosive jab and Purevdorj used a power punch with 56 seconds left for a 4-2 lead.

In the third, Yanez connected several combinations in a 20-second span to grab a 6-5 edge before Purevdorj drew even. Purevdorj scored the only points of the fourth, once avoiding a Yanez punch by tackling him to the ground.

“We wanted him to engage the guy and try to get up and make the guy have to come to him,” Campbell said. “He started playing the waiting game from the beginning. We were yelling to him. We talked to him in between rounds.”

Yanez heard all of his corner’s pleas.

“They were trying to tell me to go at him, go at him, go at him,” he said. “I’m not that fighter. If I do, I’m going to go in there, and I’m going to get caught with shots. I want to go out there and play it smart, keep my hands up.”Campbell disagreed with the strategy.

“He’s actually a very aggressive boxer,” Campbell said. “One of the things that has always helped Luis is his aggression. He didn’t exhibit that. For some reason, he decided to stand back and wait, and that cost him.”

Asked about his standing with Campbell, Yanez said, “I really don’t want to put anything on that subject. I just want to go back to my family right now.”

Campbell said his relationship with his boxers is “always the same. I’m here for them. They’re in it for their own reasons. And the way they box in the ring, they do it for their own reasons.”-CONTACT THE WRITER: 636-0256 or brian.gomez@gazettedev.gazette.com.
