Oscar Valdez started slow. Robson Conceicao was fighting the fight of his life. The champion then turned it around. Valdez retained his WBC super featherweight world title Friday evening with a unanimous decision (115-112 2x and 117-110) over 2016 Brazilian Olympian gold medalist Conceicao in front of a sold-out crowd of 4,545 at Casino Del Sol.

It was the first defense of the WBC title for Valdez, who stunned the fight world with an upset knockout win over Miguel Berchelt earlier this year.

Conceicao (16-1, 8 KOs) appeared to take the early lead, but as the fight approached the second half, the come-forward Valdez narrowed the gap and overtook the upstart. One judge had Valdez winning the final seven rounds, while another had Valdez winning six of the final seven.

“He’s over here yelling in my face. We’re grown men. Don’t be yelling in my face. He might be upset. Of course you want to be a world champion, but don’t point at me, don’t be yelling in my face. I’ve been through enough this week, man," Valdez said.

“It makes the fight complicated when someone is trying to run the whole fight. I’m trying to put on a good show for my fans, give the fans what they want, which is a good fight. If he wants to run… you can’t win a fight running like that."

Adding insult to injury, Conceicao had a point deducted for a tap to the back of Valdez's head in the ninth round. Valdez (30-0, 23 KOs) survived with his title in tact and now looks ahead to bigger things.

Conceicao disagreed with the scores.

"This is boxing. I cannot go with his game. I played my game. Look at his face and look at my face. I have nothing on my face. Oscar’s is all f----- up. I won this fight," Conceicao said.
