Citizens Business Bank Arena, Ontario - Super bantamweight contender Brandon Figueroa (17-0 12 KOs), who is the younger brother of former world champion Omar Figueroa, knocked out Oscar Escandon (25-5, 17 KOs) in the tenth round.

This was the third fight of the year for Figueroa, who knocked out Luis Roy Cruz in one round in August and put away Giovanni Delgado in seven rounds in March.

Escandon has lost three of his last four. A split decision loss to Moises Flores in April 2015. And then a seven round knockout loss to WBC featherweight champion Gary Russell Jr. in May 2017, and then a third round knockout loss to Tugstsogt Nyambayar in May.

This contest was originally scheduled as the co-feature of the card, but was elevated when the main event - between Victor Ortiz and John Molina - fell out. Ortiz was arrested earlier this week for sexual assault, and his fight was pulled from the card.

The fight began at a quick pace. They were trading a lot of punches on the inside in the first round, and both were getting off with solid punches. Figueroa was landing better to the head, and Figueroa was connecting to the body.

They continued to brawl on the inside in the second. It was a toe to toe battle and neither fighter was stepping back. And the same trend continued in the third, with an inside war, as non-stop punches were flying from both. Figueroa was connecting the better punches, but suffered a cut around his left eye.

The pace slowed down in the fourth. Figueroa was now fighting at a distance and looking to outbox Escandon. He wobbled Escandon with combination in the closing moments. In the fifth, Escandon applied more pressure to force a fire fight and Figueroa was happy to oblige. Escandon was wobbled again, but fought his way out of trouble.

Figueroa controlled the action for the next few rounds, with Escandon being game and hanging in there. In the tenth and final round, Figueroa landed a big uppercut that sent Escandon down and he was in no condition to continue - with the referee stopping the contest.
