Canelo Alvarez vs. Sergey Kovalev results: Canelo a four ...

Saul "Canelo" Alvarez’s inaugural flirt with the 175-pound division was a successful one, as he stole Sergey Kovalev’s WBO title with a stunning 11th-round stoppage. In what was atactical battle from the outset, both men demonstrated incredible levels of skill, and with the fight heading toward a tight finish, Alvarez found enough to flip it in his favor.

Much had been made about the task facing Alvarez because of Kovalev’s advantages in size and power, but the Mexican icon appeared to have him worked out by halfway through the bout. Kovalev rallied brilliantly as the fight reached the business end, and when discussions were being formed on how the scorecards might look, Alvarez unleashed a left hook that rendered the judges useless as he became a four-division world champion.

Afterward, Canelo was not eager to pinpoint his next move, but after enhancing his legacy with another remarkable win, it's fair to assume that he'll relish whatever challenge awaits him. With a current stake in three divisions, Canelo has a ton of options awaiting him, but for now, time should be spent applauding his mastery instead of speculating on who he may fight next.

As for Kovalev, he now has a big decision to make. A narrow loss on the scorecards may have bought him a campaign for a justified rematch, but the way he was stopped might persuade him to draw the curtains on what has been a wonderful career.

1:07 a.m.: Kovalev confirms his position as the "B" side by walking to the ring first despite being the defending champion.

12:58 a.m.: Our main event is almost here. National anthems are currently taking place in the ring. Fans have waited a long time for this fight. Kovalev is shown on big screen hitting the pads of Buddy McGirt.

12:45 a.m.: Is frustration setting in for either fighter? A lengthy delay while waiting for UFC 244 to end means that both fighters have been prepared for well over an hour. How will this impact their mindset heading into the eagerly anticipated battle?

Buddy McGirt is no stranger to what could occur tonight. Back in 2006, McGirt was Antonio Tarver's trainer when Tarver gave up his 175-pound supremacy to Bernard Hopkins. "The Executioner" was making his debut at light heavyweight after a lengthy run at 160 pounds. McGirt will be praying history doesn’t repeat.

Round 1: Garcia's long arms come intoplay early, and then he finds a stunning shot to end the fight. That’s how you answer your critics. Duno is receiving medical attention as Garcia is mobbed by Oscar De La Hoya and Bernard Hopkins.

A beaming Garcia watches the stoppage in his postfight interview and is pleased with what he sees. He says it’s an honor to train alongside Canelo and thanks his entire team. Garcia welcomes better competition in 2020.

11:31 p.m. We’re now ready for the night's chief support. Romero Duno and Ryan Garcia have made their way to the ring.

11:15 p.m. Up next is Ryan Garcia vs. Romero Duno. Garcia’s profile grow massively this year thanks to his social media platforms, but now is the time for him to be judged for his fighting prowess. A solid win tonight can provide a platform for bigger fights, but more difficult tasks lie beyond Duno in 2020. Can Garcia close the year in style, or is Duno going to expose his hype? We’ll find out shortly.

We finally get the official word following a lengthy delay for negotiations between officials. Scorecards are 90-81, 89-82 and88-83 in favor of Estrada. The action was stopped before the 10th round because of a hellacious cut to Esparza following an accidental clash of heads.

Estrada said after the fight that she is old school and would love to fight 15 rounds. She’s insistent that she wants belts.

Esparza apologized to the crowd for not answering the bell for final round. She said she was surprised by the one-sidedness of the scorecards and that she’d welcome a rematch.

10:45 p.m. The fight has been halted because of the cut. Estrada is celebrating, but we'll go the scorecards because the laceration was caused by a head-butt.

10:44 p.m. Heading into the final round, you have to assume that Estrada is ahead. Esparza has been ridiculously brave, but she has struggled to put together two good consecutive rounds. Estrada has had the last word on most of the exchanges, and she should be ahead as we approach the final stretch.

10:39 p.m. Extreme naivete from Esparza: she is caught with several shots while complaining to the referee about an Estrada head-butt. A little over two rounds remain in this bloody encounter, and Estrada looks the freshest.

10:37 p.m. When it appeared Esparza was on the way out, she produces a useful round that was full of industry. A lot of cheerleading now going on in her corner as her trainer gives her instructions.

10:33 p.m.: Esparza is displaying signs of distress as she slumps on her stool after Round 6. Is she feeling the pace after what has been a grueling battle?

10:27 p.m. Disaster strikes for Esparza; she’s cut from a head-butt halfway through Round 5. We’ve passed four rounds, so if the cut becomes too problematic to continue, we’ll go to the scorecards early. The cut man in Esparza’s corner is in for a busy night.

10:15 p.m. It has been a lively start from both fighters as they look to make an early impression. The left hand from Esparza has been the fight’s most dominant feature.

10:05 p.m.: There's decent applause inside the venue as Seniesa Estrada and Marlen Esparza are introduced to the crowd before their WBA interim women's flyweight title clash.

9:45 p.m.: Cobbs def. Ortiz by TKO at 3:00 of the sixth round to win the vacant NABF welterweight championship.

Ortiz dropped Cobbs at the end of the first round, but Cobbs made sure to stay away from Ortiz's left hand after that. Cobbs knocked down Ortiz in the sixth round, and after going to his corner, Ortiz could not come out for Round 7. The body shots added were too much for him to continue.

Evan Holyfield def. Nick Winstead by TKOat 0:16 of the first round

Holyfield, the son of boxing legend Evander Holyfield, went right at Winstead and dropped him almost immediately. Winstead got up, but the referee stopped the four-round fight.
