Jaime Munguia vs. Patrick Allotey result: Munguia defends WBO 154-pound title with fourth-round TKO

CARSON, Calif. — If this was his last fight as a junior middleweight, then WBO champion Jaime Munguia certainly left his mark on the division.

In front of his fans on Mexican Independence Day, the 22-year-old shook off a slow start to brutalize Patrick Allotey for a fourth-round TKO after Allotey's corner had seen enough of their fighter getting beaten up. The title fight served as the main event at Dignity Health Sports Park and was streamed live on DAZN.

Munguia (34-0, 27 KOs) made his fifth title defense a successful one with a scintillating performance. The young Mexican star sent Allotey to the canvas on three occasions, and with former champion Erik Morales in his corner as his new head trainer, Munguia demonstrated a heightened fight IQ as he cut off the ring and kept his opponent from using his movement to escape his advances.

It was quite the turnaround for Munguia after a subpar performance in April, when he escaped with a decision victory against Dennis Hogan. Here we saw a determined Munguia take a couple of rounds to figure out what his opponent had before opening up the toolbox in the fourth.

To his credit, Allotey (40-4, 30 KOs) had some success early as he landed combinations to keep Munguia from shrinking the ring. Unfortunately, those punches had no effect on Munguia. By the third round, Munguia had seen enough and plowed right into his Ghanaian opponent from Ghana. Pinned against the ropes, Allotey couldn't find an escape route and was punished with a body and head combination that was punctuated by a short uppercut. Allotey took a knee but was damaged goods at that point.

Allotey attempted to circle away but again found himself the recepient of a hard combination that sent him to the canvas as the round ended. He made it to his feet but his corner wasn't too thrilled with letting him return for another round. With blood in the water, Munguia went on the hunt and plowed through Allotey with yet another combination that put Allotey down after a delayed reaction. He again managed to get to his feet, but his corner had seen enough and called a halt to the fight at the 2:18 mark.

Although he wouldn't commit to this being his final fight as a junior middleweight, the tough weight cut may have been too much for Munguia. A future at middleweight, where the names Canelo, Golovkin and Andrade rule, is where his true test lies.

Franchon Crews-Dezurn unifies titles with unanimous decision over Maricela Cornejo

Result: With scores of 98-92, 98-92 and 97-93, Crews-Dezurn unifies her WBC super middleweight title with the previously vacant WBO title. The flashy Crews-Dezurn improves to 6-1, with her only loss coming to Claressa Shields. Crews-Dezurn demands respect from her peers on the microphone after an impressive performance.

11 p.m.: Cornejo fought well but will likely come up short as the fight goes the full 10 rounds. Crews-Dezurn remained aggressive throughout and landed some heavy leather. Cornejo certainly could have benefited from a full camp; she demonstrated that she could have been more competitive than she was tonight.

10:46 p.m.: We're in the sixth round and Cornejo is coming off a round where she landed some big shots on the champion. It's certainly getting interesting. Cornejo may have just taken the last two rounds as she finishes the sixth just as strong with a thudding left hook that catches Crews-Dezurn flush.

10:33 p.m.: For someone who lost to Crews-Dezurn exactly one year ago and stepped up to take the fight on two days' notice, Cornejo is making a solid account of herself against the champion. Crews is aggressive and landing the harder shots but Cornejo is here to fight. After three rounds, Crews-Dezurn is up but it hasn't been a walk in the park.

10:29 p.m.: The co-main event is up next. Moving up in that slot is WBC women's super middleweight champion Franchon Crews-Dezurn (5-1, two KOs) defending against last-minute replacement Maricela Cornejo (13-3, five KOs), whom Crews defeated previously. Crews' original opponent was unable to secure her visa and Cornejo was brought in Friday.

10:06 p.m.: Another fight, another retirement on the stool between rounds. Try as he might, Ivan Delgado simply couldn't keep up with the pressure and power punching of Romero Duno and his corner decided that enough was enough at the end of the seventh round. Duno looked sharp but he did deal with a fair bit of adversity from the rough and rugged Delgado. After the fight, Duno put on a shirt that read, "Ryan Garcia, stop running." Well, we know what he wants. Will his 21st victory lead him to a showdown with Garcia? We'll see.

9:55 p.m.: We've got a pretty good scrap between Duno and Delgado going as we head into the fifth round. In the previous round, Duno hurt Delgado to the body and it looked as if he was going in for the kill, but Delgado sucked it up and, to the delight of the fans, willed himself back into the fight.

9:38 p.m.: Up next is "Ruthless" Romero Duno (20-1, 15 KOs) taking on Ivan Delgado (13-2-2, six KOs). If the name Duno rings a bell, it is because he was going to be the replacement opponent for Ryan Garcia. The interesting thing is that a Garcia-Duno fight has been discussed for several months and the two were likely positioned to fight on the same card to set up a future showdown. One would have to think that a Duno victory would set up that fight with Garcia.

9:27 p.m.: Olea took a lot of punishment and decided to call it a night at the end of the fourth round. It was a pretty one-sided fight from the beginning, with Rafael Gramajo punishing the body and head with power shots throughout. We get yet another knockout on this card.

9:14 p.m: It has been quite the interesting day here at the park formally known as Stubhub. Earlier, the action was delayed because the Los Angeles sun was causing the canvas to melt. A crew had to ice down the canvas to get it back to something manageable and safe. With that out of the way, we're on to the action. We've had a few knockouts, and the main card has opened with Rafael Gramajo (10-2-2, two KOs) fighting Daniel Olea (13-8-2, five KOs). We're in the third round and Gramajo has been in control throughout.
