LAS VEGAS — Canelo Alvarez retained his undisputed super middleweight championship on Saturday at T-Mobile Arena with a unanimous-decision victory over his rival, Gennadiy Golovkin, in a trilogy fight.

Two judges scored it 115-113, while a third judge turned in a 116-112 tally for Alvarez.

After the final bell, and 36 rounds together, they shared a long embrace, apparently ending a feud that grew personal over the years.

Golovkin, at age 40, started incredibly slow and barely threw a right hand over the first two quarters of the bout, but came on strong late and appeared to win the final four rounds. — Mike Coppinger

Round-by-round analysis:

Official result: Canelo Alvarez retains his undisputed super middleweight championship via unanimous decision against Gennadiy Golovkin: 116-112, 115-113 and 115-113. Fair scores. Had it 116-112 with GGG sweeping final four rounds.

Round 12: Golovkin is the aggressor while Alvarez, who appeared to fade down the stretch, held on. GGG again goes to work with the jab, and they share a long embrace at the bell, the grudge match seemingly settled. 10-9, GGG. 116-112, Alvarez.

Round 11: Golovkin busts Alvarez’s right eye open, and it appears to be a deep gash. He controlled the action and landed some big shots for the third consecutive round, but it’s probably too little, too late. 10-9, GGG. 107-102, Alvarez.

Round 10: Golovkin picks up where he left off and connects on a few sharp right uppercuts on the inside. He kept the jab pumping in Canelo’s face to great effect. 10-9, GGG. 98-92, Canelo.

Round 9: GGG finally opens up and lands some thudding shots after he pinned Canelo into a corner. Alvarez responded with a few hard lefts but GGG, at long last, clearly wins a round. 10-9, Golovkin. 89-82, Alvarez.

Round 8: Canelo begins to pick up the pace with a series of thudding shots, while GGG sticks with the jab, and not the right hand that made him an elite fighter. 10-9, Alvarez. 80-62, Alvarez.

Round 7: GGG is known for slow starts, but it’s now the second half of the fight and he’s yet to get going. At 40, he appears to simply be too old to hang with one of the best in the game. 10-9, Alvarez. 70-63, Alvarez.

Round 6: The first fight was all action; the second was a classic. The third, halfway through, has been anything but. GGG refuses to throw right hands, surely weary of Canelo’s dangerous counter left hook. 10-9, Alvarez. 60-54, Alvarez.

Round 5: Alvarez continues to pound GGG’s body with right hands, and lands his biggest punch of the fight, an overhand right that crashed into GGG’s face late in the round. Golovkin was more aggressive but still didn’t come close to letting his hands go. 10-9, Canelo. 50-45, Canelo.

Round 4: GGG has yet to really throw a combination while Alvarez pelts him with right hands to the body and left hooks to the head. GGG’s face swelling up, particular his right cheekbone. All Alvarez through four. 10-9, Alvarez. 40-36, Alvarez.

Round 3: GGG must find a way to stand his ground. He’s being pushed back, and Alvarez is having his way. Canelo connected with a big left hook that forced Golovkin to hold on, and GGG emerged with a large welt on the right side of his forehead. 10-9, Alvarez. 30-27, Alvarez.

Round 2: Alvarez scored with a right hand to the liver followed by a left hook to the body. He later connected with a powerful overhand right. GGG has been patient thus far — he’s always been a slow starter. 10-9, Alvarez. 20-18, Alvarez.

Round 1: They’ve competed 24 rounds against each other, but it’s been four years since they last faced each other, so it was a slow opening round. GGG established the jab early on while Canelo swung wildly and did connect with one sharp, compact left hook. 10-9, Alvarez.

Ring announcer David Diamante is making the fighter’s introductions, first GGG, then Canelo. The fight is next.

GGG had to wait 6 minutes inside the ring before Canelo got there. He was relaxed.

GGG is in the ring. Canelo is making his way out. Mexican singer Alejandro Fernandez is leading him singing “Mexico Lindo y Querido.” The scene inside the T-Mobile is incredible.

Results:

“Bam” Rodriguez retains title in decision win

A showcase bout turned into a pretty tough test for one of boxing’s hottest names. Jesse “Bam” Rodriguez, the WBC junior bantamweight champion, topped Israel Gonzalez in a unanimous decision, 118-109, 117-110, 114-113, in the co-main event.

Rodriguez didn’t get the stoppage that could have accelerated his stock and admitted afterwards that it was a tougher fight that he expected. But the 23-year-old strengthened his case to be the 2022 fighter of the year.

While the crowd filled into their seats at T-Mobile Arena, Rodriguez displayed the dominance that has permeated the last few months.

Early in the fight, it didn’t really matter where the action occurred. In the middle of the ring, on the ropes, at distance, in close quarters — Rodriguez (17-0, 11 KOs) landed. The only major slipup came in the eighth round, when referee Kenny Bayless docked Rodriguez a point for a low blow that left Gonzalez kneeling for several minutes.

The champion from San Antonio did a lot of damage with the power left hand out of his southpaw stance. He also popped Gonzalez (28-5-1, 11 KOs) with a few uppercuts. The challenger from Baja California Sur, Mexico, was active and gave one of boxing’s rising champions a good test.

But it was to no avail. Rodriguez landed the harder shots and dictated the terms of engagement. Rodriguez faded a bit toward the final rounds as he tried to put his opponent away. But the veteran who lost a unanimous decision to Roman “Chocolatito” Gonzalez scrapped his way to the final bell.

Earlier in the year, Rodriguez fought Carlos Cuadras on less than a week’s notice to win the 118-pound championship. Then he followed it up with a knockout win over Srisaket Sor Rungvisai.

Saturday’s effort wasn’t the Texan’s best performance of the year, but he still showed plenty of flashes of dominance, and he’s only getting started. — Ben Baby

Akhmedov wins every round against Rosado

As always, Gabriel Rosado was a stubborn and tough opponent. But Ali Akhmedov had patience and perseverance against one of boxing’s most rugged veterans. Akhmedov didn’t drop a single round on all three scorecards and won a unanimous decision, 100-91.

The Kazakhstan fans settled into their seats, several of them waving the country’s blue and yellow flag, cheering on their fellow countryman as Akhmedov (19-1, 14 KOs) connected often at distance. Rosado (26-16-1, 15 KOs), a Philadelphia native who now lives in Puerto Rico, struggled early but seemed to find his bearings in the later rounds. He was successful in the ninth and 10th rounds and even forced Akhmedov to retreat at times.

However, it wasn’t enough to move the judges to score any round for him. Akhmedov won his third straight bout. — Baby

Williams scores unanimous-decision win

It wasn’t always pretty, but Austin “Ammo” Williams got the job done.

The Houston native scored a unanimous decision over Kieron Conway in the first fight on the pay-per-view portion of tonight’s card, 96-93, 97-92, 97-92.

It was a fight that was more fascinating than interesting. Conway was throwing scoring shots and had Williams fighting tentatively early throughout the fight. In the sixth round, Conway landed a right hand that momentarily stunned Williams (12-0, 9 KOs).

But everything flipped in the ninth round. Williams caught Conway (18-3-1, 4 KOs) with a lead right hand that caused Conway to buckle near the ropes and eventually scored a knockdown. — Baby

Pacheco scores another TKO win to stay unbeaten

The plan for Diego Pacheco worked.

Anyone who could read a betting sheet knew the objective of his match against Enrique Collazo. Pacheco, a dumbfounding favorite (-3000), was expected to finish Collazo quickly to interject some buzz into his career.

Pacheco did his part. The Los Angeles native put Collazo (16-3-1, 11 KOs) down in the fifth round. When Collazo got back to his feet, Pacheco quickly swarmed his Puerto Rican opponent and forced a stoppage.

While the fifth round was entertaining, it’s still unclear just how good Pacheco (16-0, 13 KOs) can be. Better competition could indicate where Pacheco’s ceiling may be. — Baby

Top prospect Castro stops Montiel in Round 5

Lightweight prospect Marc Castro picked up a stunning knockout on a punch that Kevin Montiel never saw coming.

In the fifth round of a fight Castro had dominated, he unleashed a massive right uppercut that flattened Montiel and prompted referee Tony Weeks to immediately stop the bout. Montiel (6-1, 3 KOs) was on his back for around two minutes before he eventually sat up and received a round of applause from the crowd inside the arena.

Castro (8-0, 6 KOs) picked up his first stoppage in his last three fights, with all of those bouts occurring this year. The Fresno, California, native has been consistently featured on Alvarez’s undercards, which shows just how much promoter Matchroom thinks of Castro. — Baby
