Saul ‘Canelo’ Alvarez dominated Gennady Golovkin over 12 rounds to retain his undisputed super-middleweight titles.
It was the third encounter in Las Vegas between the modern day greats with Alvarez claiming a second win following a controversial draw in the first bout.
After sidestepping a fightback from Golovkin in the later rounds, all three judges were in agreement, scoring it 116-112, 115-113, 115-113 for Alvarez.
“Thank you my friend, we gave the fans three great fights,” said the Mexican.
They had a warm embrace after the fight, despite their rivalry turning sour in the four-year wait for the trilogy encounter, which saw Alvarez retain the IBF, WBA (Super), WBO and WBC titles.
Golovkin said: “I want to shake hands with Canelo. Congrats to all his team. He’s a real warrior, if you don’t understand that, you don’t understand nothing.”
Thrilling trilogy ends with a whimper
Despite a bitter build-up, the final chapter did not have the same bite as the previous two contests in 2017 and 2018.
Alvarez, 32, took control from the first round, dominating an unusually passive Golovkin.
Golovkin was happy to “see the rounds slip away”, as Steve Bunce on BBC Radio 5 Live commentary put it, and at the halfway point the unified middleweight champion was experiencing a shutout.
Although showing no signs of hurting Golovkin, Alvarez set the pace and was particularly successful with his left hook.
Golovkin could not respond when Alvarez did land and after the eighth round the Kazakh’s trainer Johnathan Banks tried to rally his fighter, telling him “let’s go to work”.
The 40-year-old tried to do just that and staged a fightback from the ninth round onwards, his famous stiff jab finally clicking into gear, troubling Alvarez and pushing him back.
Alvarez, however, while visibly tiring, was never hurt and going into the final round Golovkin was searching for what would have been the 38th knockout of a long career.
The T-Mobile Arena in Las Vegas had been an unhappy hunting ground for Golovkin, losing the rematch to Alvarez there in 2018 and being robbed of what many felt was a superb win in their first fight in 2017.
And it was to be another frustrating night for Golovkin, who lost for just the second time in his illustrious 45-fight career.
What next for Golovkin?
Many had felt Golovkin could walk away from the sport should he lose.
But he confirmed he had no intention of hanging up his gloves after Alvarez’s promise to send Golovkin into retirement with a knockout victory proved overzealous.
Golovkin, who stepped up to the 168lb super-middleweight division for the first time for this fight, is still the IBF, IBO and WBA (Super) champion at middleweight.
“Absolutely” Golovkin said when asked he would continue fighting. “I have a great plan. Congrats to Canelo and all boxing fans. I have three belts in 160lbs, I come back, I’m still champion.”
‘I need rest’ – Alvarez
Alvarez returned to winning ways after his move up to light heavyweight ended in defeat against WBA (Super) champion Dmitry Bivol last time out.
It was just the second loss of his career but the Mexican confirmed his next target is to avenge that defeat.
Bivol, unbeaten in 20 fights, will first defend his title against Gilberto Ramirez on 5 November.
Alvarez, who revealed he had been suffering from a hand injury before his win over Golovkin, will look to fight Bivol on his return next year.
“I left everything in there. I need surgery on my hand, I’m not good in my left hand,” he said.
“Everybody knows [Bivol is the fight I want]. We’ll see what happens in that fight. But I need rest.
“It’s very important for my legacy, for my pride, for my family and my country. I will beat him.”
