Undercard Results Former middleweight world champion David Lemieux tore into Glen Tapia and never relented until the fight was over in the fourth. After digging furious shots to the head and body from the opening bell, the Canadian crashed through with a sensational left hook-right hook combo to the noggin, flooring Tapia (23-3, 15 KOs) face first into the bottom rope. The New Jersey fighter climbed back to his feet but as soon as referee Russell Mora was about to let the young contender continue, his cornerman stepped onto the ring apron and through in the proverbial towel. Mora obliged and waived it off, officially ending the one-sided shellacking just 56 seconds into the fourth. Lemieux (35-3, 32 KOs) said afterward that he wants to fight the top guys at 160, somewhat singling out the winner of Canelo-Khan later tonight.



Mauricio Herrera had been robbed a few times of victory throughout his underrated career, but Saturday night in Las Vegas was not one of those times. Unbeaten contender Frankie Gomez was too fast and too accurate for the older Riverside fighter to handle and “The Pitbull” dominated him for every minute of every round. Herrera was never on the verge of being knocked out in the welterweight scrum, but he was a step or two behind his foe from the start and was never able to get a rhythm going whatsoever. In the end, Gomez, from East Los Angeles, was awarded a lopsided unanimous decision via tallies of 100-9 on all three scorecards, allowing him to rise to 21-0 with 13 KOs. Herrera fell to 22-6 with 7 KOs.



After muscling his younger foe around the ring in the opening frame, Brooklyn’s Curtis Stevens took Patrick Teixeira out with one punch in the second. Teixeira was game throughout but his chin couldn’t withstand the sheer brutality of Stevens’ power. After Teixeira landed a left uppercut from a little too far outside, Stevens delivered a ferocious overhand right that exploded on the Brazilian’s jaw, sending him spiraling to the canvas. He was able to beat the count but referee Tony Weeks didn’t like the way he was responding to his questions and intelligently waived the battle off. The official time of the TKO came just 64 ticks into the second frame, allowing Stevens to soar to 28-5 with 21 knockouts. Teixeira dipped to 26-1 with 22 KOs.



Junior featherweight prospect was supposed to be one of Diego de la Hoya’s toughest tests to date. As it turned out, the Mexicali fighter passed the exam with flying colors as he stopped his foe in the seventh. De la Hoya scored a slick knockout of the Californian in the second when he countered a left-right with a straight right to the jaw and then systematically broke him down until the end. Finally, with his face busted up and taking too many clean punches, referee Jay Nady had no choice but to step in and waive it off at 1:59 of the seventh, saving Santomauro any further punishment. The win allowed de la Hoya to improve to 15-0 with his ninth pro stoppage; Santomauro fell to 13-1 (1).



Though many expected Ireland’s Jason Quigley to knock out fellow middleweight James De La Rosa, the young prospect was still as dominant as ever, pitching a shutout on the cards over 10 rounds. Quigley picked the Texan apart from the start and landed several hard punches to the head and body but De La Rosa (23-4, 13 KOs) was as resilient as ever and stayed upright throughout the duel. In the end, all three ringside officials favored Quigley (11-0, 9 KOs) by the margin of 100-90.



Young lightweight prospect Lamont Roach Jr. out-boxed Jose Arturo Esquivel over eight rounds, winning a hard-fought but well-deserved unanimous decision. The Washington DC fighter was much fatser and more accurate with his punches throughout and was given the nod thanks to scores of 79-72 on all three official cards. The win bolsters Roach’s pro ledger to 11-0 with 4 KOs while Esquivel, from Mexico, falls to 9-5 with 2 KOs.



Junior middleweight prospect Rashidi Ellis kept his perfect record intact as he dominated tough Mexican veteran Marco Antonio Lopez for eight rounds, winning a lopsided unanimous decision. The Bostonian used his far superior hand speed to lead and counter his foe from the start and coasted to a unanimous decision win via tallies of 80-72 on all three official scorecards. Ellis improved to 15-0 (11) with the boxing clinic; Lopez dipped to 24-9 with 15 KOs.
