Oscar Valdez, the WBC junior lightweight world champion, defends his title against Robson Conceicao in Tucson, Arizona on Friday (ESPN+, 10 p.m. ET, with undercard bouts beginning at 6:10 p.m. ET).

In August, Valdez tested positive for the prohibited drug phentermine, but the Pascua Yaqui Tribe Athletic Commission permitted him to compete at the Casino Del Sol. The World Boxing Council opted not to strip Valdez of his championship, claiming that “this is not a performance-enhancing substance” and that “Valdez will have absolutely no advantage and the challenger will be at no danger.”

Luis Alberto Lopez won the 10-round co-feature against Gabriel Flores Jr., a shellacking from bell to bell of the unbeaten prospect — and a 13-1 underdog. Lopez won the bout on all three judges’ scores of 98-92, 100-90, and 100-90.

Lopez (23-2, 12 KOs) was unrelenting in his pursuit of Flores, round after round. Flores’ trainer and father, Gabriel Flores Sr., told his son that the fight would be stopped before the 10th and final round. The 130-pounder begged and begged, and his father agreed. Flores Sr. notified the commission supervisor to halt the fight with approximately 10 seconds remaining in the round, since Flores was taking more and more damage, but the referee never saw him on the apron.

“I was staring at the referee, expecting the fight to be halted,” Lopez stated via a translator. Flores’ left eye was severely swollen as a result of the barrage of power shots he was bombarded with. He was shut out on two of the three cards because he had no replies. Flores, who was visibly upset, said, “He f—-ing humiliated me.” “He was f—-ing up my whole body. I’m very dissatisfied with myself. There are no justifications. Nobody cares about what occurred. You either won or lost.”

Top Rank has steadily developed the 21-year-old from Stockton, but it’s uncertain where he’ll go from here. Flores (20-1, 7 KOs) had just stopped Jayson Velez in the sixth round.

Lopez landed 142 power punches compared to Flores’ 68. Lopez, a natural 126-pounder from Mexico, has also defeated Andy Vences.

However, Nakatani continued to land blows to the nose, causing more and more blood to splatter over the ring. Acosta battled valiantly, but his championship defense came to a halt at 32 seconds of Round 4.

“I got him square in the nose in the first round,” Nakatani stated via an interpreter. “I realized [it was broken]… I’d want to unify the titles,” she says.

Nakatani (22-0, 17 KOs) was fighting abroad of his home Japan for the first time. The 23-year-old was making his first defense of the 112-pound championship he won against Giemel Magramo in November with an eight-round KO.

Acosta (22-3, 21 KOs) was a 108-pound champion who successfully defended his title three times until being stopped in the 12th round by Elwin Soto in June 2019. At 112 pounds, the 30-year-old Puerto Rican is rated No. 9 by ESPN.

The 19-year-old Puerto Rican beat Jose Luis Sanchez by unanimous decision — 60-53, 60-54, and 60-53 — in his hardest test to yet. He dominated for the most of the six-round battle, but he also displayed certain weaknesses that need to be addressed in the gym.

Zayas (10-0, 7 KOs) was an offensive machine who had excellent punch variety and aggressiveness, but he was also hit hard throughout the fight. In Round 3, Zayas knocked Sanchez out with a powerful left hook, but the referee missed the knockdown.

“In the latter rounds, the heat got to me a little bit,” Zayas remarked after the bout. “We expected it to be scorching in Arizona. We also understood Sanchez would be a formidable opponent. He is a proud Mexican warrior who hails from a strong fighting family. I had a feeling he was coming to fight. We completed the task, and I listened to my team, boxed him, and received a unanimous decision. That is the most crucial point.”

Sanchez was coming off a draw with former title contender Adrian Granados (11-2-1, 4 KOs). By the conclusion of the struggle, the 28-year-old resident of Albuquerque, New Mexico, was dripping with blood.

Lindolfo Delgado, a 2016 Olympian, stopped Miguel Zamudio in the second round to improve to 13-0. (12 KOs).

From the first bell, the 26-year-old Mexican pounded Zamudio, scoring a knockdown in Round 2 with a right hand. Zamudio (45-18-1, 28 KOs) fought to the end of the round but was stopped on his feet 50 seconds in.

In his last six bouts, Zamudio, 30, has only won one. Delgado, a 140-pound prospect, just signed with Top Rank.

Rene Tellez Giron wore Eduardo Garza down before knocking him out in Round 7 with a vicious left hook to the body.

Giron (16-1, 10 KOs) used a short right uppercut as a throwaway punch to pull Garza’s hands down before delivering the liver blow, which sent Garza to the ground in pain. On the heels of his first professional setback earlier that year, a unanimous-decision loss to bright prospect Michel Rivera, the 22-year-old Mexican boxer stunned Carlos Balderas in 2019. At 130 pounds, Giron is suddenly a warrior to watch.

Garza (15-5-1, 8 KOs), a 32-year-old Dover, Delaware native, has already lost three of his last four fights.


To remain undefeated, Aguilar stops Portillo.

With a second-round KO of Carlos Manuel Portillo, Omar Aguilar, 22, rose to 22-0 (21 KOs). In the last seconds of Round 1, the lanky 140-pounder scored a knockdown, and then finished him out with two more knockdowns in the first few seconds of Round 2.

As the ref reached the count of ten after the third knockdown, Portillo was favoring his right eye while on the canvas. The eye was damaged by a compact left uppercut, giving Aguilar the victory in his debut fight outside of Mexico.

Portillo, a 28-year-old Paraguayan, was defeated for the fourth time in his last five bouts.
