In a walkout bout after the main event undefeated super lightweight Arnold Barboza Jr., 141.6, dominated Luis Solis, 142, before the ringside physican stopped the fight in the corner after round five due to the severe swelling around the right eye of Solis. Barboza dominated the fight with his jab and had the eye closing early and by round four it was clear that Solis was on borrowed time as the eye rapidly swelled shut. With the win Barboza improves to 19-0, 7 KOs while Solis falls to 23-10-4, 20 KOs.

Undefeated super featherweight prospect Robson Conceicao, 129.8, dominated Edgar Cantu, 129, of Laredo Texas over eight rounds. Conceicao, a 2016 Olympic gold medalist, showed tremendous skill during the course of the eight round fight but did seem to coast at times. Conceicao wisely utilized his height and reach advantage early on, peppering the Texan with right hands and punishing the body of Cantu whenever Cantu managed to get inside. By round three it seemed clear that the body attack was already starting to pay dividends as Cantu stopped throwing shots and seemed content to just follow the Brazilian around the ring. By round four the body attack seemed to turn the tide and although Conceicao was earned for a low blow the fight seemed to be entering the next stage before a stoppage. A viscous right hand dropped Cantu in round six and the Brazilian seemed poised to up the ante and stop the Texan, but he eased up in round seven and eight, electing to easily slip Cantu’s punches and pepper him with eight hands. All three judges scored the fight 80-71 for the Olympian, who improves to 9-0, 5 KOs. Edgar Cantu now sees his record fall to 7-5-2, 1 KO.

Undefeated female super featherweight Mikaela Mayer, 129.4, dominated Hungarian Edina Kiss, 128.6, scoring a stoppage at the beginning of round four when Kiss told her cornerman she couldn’t continue after the end of round three. Kiss never could get inside the reach of Mayer, who dominated the fight from the opening bell. Using her reach and size advantage Mayer dropped Kiss in the opening seconds of the first round and finished the round with a solid right hand that rattled the Hungarian a second time. Mayer continued to pick apart Kiss from the outside in round two and had Kiss backing up for much of the third as the American applied relentless pressure. With the win Mayer improves to 7-0, 4 KOs while Kiss falls to 15-8, 9 KOs.

Undefeated Carlos Castro, 121.4, of Phoenix Arizona won a lopsided decision over Diuhl Olguin, 121.2, of Guadalajara Mexico over eight rounds. Olguin was never able to find an answer for the speed of Castro, who picked the Mexican brawler apart over eight rounds. Scores were 80-72, 79-73 and a somewhat surprising 77-75. With the win Castro improves to 21-0, 9 KOs while Olguin drops to 12-12-2, 9 KOs.

Phoenix Arizona’s Francisco De Vaca, 124.4, scored a workmanlike eight round decision over Nogales Mexico’s Jesus Serrano, 126.8. Serrano tried to apply pressure against the undefeated Arizonan but although he had his moments he was simply unable to cope with the speed of De Vaca, who often responded with every Serrano flurry with one of his own. Judges Dennis O’Connell and Chris Wilson scored the fight 78-73 while Judge Glenn Feldman scored the fight 79-72. The referee was Tony Zaino. With the win De Vaca improves to 19-0, 6 KOs while Serrano falls to 17-7-2, 12 KOs.

In what can only be considered something of a minor upset, lightweight contender Antonio Lozada Jr., 137, of Tijuana was held to an eight round draw by Ensenada Mexico’s Hector Ambriz, 136.6. There were no knockdowns but Ambriz came out strong and had Lozada backing up for much of the first four rounds before fading in the second half of the fight. Judges at ringside had it scored 79-73 for Ambriz (Lisa Giampa), 78-74 for Lozada (Dennis O’Connell) and 76-76 from Craig Harmon. The referee was a Richard Soto. Ambriz now sees his record stand at 12-7-2, 6 KOs while Lozada sees his record now stand at 40-2-1, 34 KOs.

Undefeated light heavyweight prospect Trevor McCumby, 172.4, of Phoenix destroyed veteran Jessie Nicklow, 169.8, of Baltimore in front of his home town crowd by way of third round TKO. McCumby looked solid from the opening bell and badly hurt Nicklow with a right hand in the opening minute of round three. Referee Tony Zaino waved off the fight at 0:40 of the round. Although Nicklow complained about the stoppage there were few ringsiders who ageeed with him as the fight appeared to be stopped at the appropriate time by Zaino. With the win McCumby improved to 24-0-1, 19 KOs while Nicklow drops to 27-9-3, 9 KOs.

In the opening fight of the afternoon undefeated super welterweight prospect Sagadat Rakhmankul, 150, of Oxnard, California by way of Kazakhstan won a lopsided decision over Christian Aguirre, 151.2, of West Valley Utah. Aguirre was at times wild and about as far from polished as you could get in a prize fighter. But what he lacked in finesse he made up for with grit and unrelenting pressure. Unfortunately for him the Kazak remained calm, collected, and possessed an impressive arsenal of counterpunches that included a picture perfect overhand right that rattled Aguirre in round five and landed with regularity throughout the fight. There were no knockdowns and all three judges had Rakhmankul winning by a comfortable margin (59-55 on two cards and 60-54 on the third card). With the win Rakhmankul improves to 3-0, 1 KO.

Undefeated rookie Breenan Macias of Goodyear, Arizona, 116.8, impressed the hometown crowd with an impressive second round TKO over journeyman Philip Adyaka, 118.4. Adyaka was a seasoned veteran with 18 pro fights, and although his record was hardly impressive there were still some fans wondering if Macias would be tested by the St. Paul, Minnesota native. But Macias came out swing for the fences from the opening bell and dropped Adyaka with a picture perfect overhand right in the closing seconds of round two, prompting referee Tony Weeks to wave the fight off at 3:00 of the second round. With the win Macias improves to 3-0, 2 KOs while Adyaka drops to 7-12, 4 KOs.
