For Golovkin, the fight seemed to be centered on his trademark stiff jab, while Canelo appeared the more active of the two boxers, ripping shots to his opponent's body with great effect.
Somehow, the two most popular and dominant men in the middleweight division returned to the T-Mobile Arena in Las Vegas and found a way to match - if not exceed - the action of their previous affair.
The win wiped away months of simmering acrimony which stemmed from Alvarez's failed drugs test in February, forcing the cancellation of a rematch scheduled in May.
He said: "If I was going to edge for one of them, I'd edge for Golovkin".
The first bout between the two boxers in September 2017 ended in a controversial draw.
Starting out as a respectable competition between two of the elite middleweights in the world, Alvarez and Golovkin's relationship gradually soured on the road to fight two.

"I have a very small cut, but I wasn't hurt", said Golovkin. It was my plan to stand trade from the beginning. At first I aimed for the knockout, I didn't.

The Kazakhstan native will take home a guaranteed £3.1million from the contest - a £765,000 from the first instalment of his fight with Alvarez. Just because he wasn't running didn't mean we were not controlling the fight, we were. He's a very good fighter. "There was only one or two rounds between them".
Alvarez said in the days leading to the fight that he went to bed every night visualising a knockout. "Hopefully there'll be a third fight".
"If the people want another round, I'll do it again", added Alvarez, who improves to 50-1-2.
