LAS VEGAS — It’s all about business. Canelo’s business, which these days is beginning to look a little bit like a monopoly of the middleweight division and perhaps a lot more.

 The Canelo biz continued to roll on, almost as if it had been scripted Saturday night in a unanimous decision over Daniel Jacobs at T-Mobile Arena for four pieces of the 160-pound tile. Jacobs was supposed to pose a real threat. He possessed all of the things that have troubled Canelo Alvarez in the past.

But Alvarez (52-1-2, 35 KOs) is never exactly the same fighter he was in the past. He evolves. He learns. He wins. Jacobs’ quick feet, long jab and switch-hitting versality were all there. But never long enough to upset Canelo or his ceaseless march through and over any perceived difficulty.

 Good businessmen are supposed to solve problems. Canelo has.  And does.  His is a career that unfolds almost like process. Jacobs’ had his moments — in the sixth round, again in the seventh and in the ninth. But they were never more than just that: Passing moments and none ever sustained over 12 rounds.

Canelo won on all three cards – 116-112 on one and 115-113 on two. Dispute the margins. But not the victory. In the early going, Canelo flashed some slick, newfound head movement that troubled Jacobs, who had said that the Mexican struggled against moving targets. In the early going, however, Canelo flipped that one. He was the moving target.

 In the middle rounds, he drew Jacobs (35-3, 29 KOs) into the center of the ring, real estate that was supposed to complement Jacob’s skillset. But. But a toe-to-toe exchange in the middle of that contested canvas allowed Canelo to exert his superior power. It left Jacobs wary at a moment when he needed to be bold. His defeat was imminent.

“It was just what we thought,,’’ Canelo said in his matter-of-fact tone. “We knew he was going to be a difficult fighter but,  thank God, we did things the right way, what we were going to do. It was just what we thought because of the style of fight that he brings. But we just did our job.”

Canelo created just enough doubt in Jacobs to keep the likable Brooklyn fighter down on the cards and unable to do enough for a scorecard victory, especially in a city known to favor the Mexican on the Cinco de Mayo weekend.

 It definitely took me a couple rounds to get my wits about me, to figure out his rhythm, because he’s a pop shotter,’’ said Jacobs, who was subject to a $1-million fine for being 3.6 pounds heavier than the contracted 170 pounds in a morning weigh-in. “He was a fast guy, very slippery. It was a great contest today, I look forward to the future. I feel like I gave enough tonight to get the victory, so I’ll have to go back to the tapes to see exactly what happened.”

Jacob’s quote might be the first in which a rival fighter has called Canelo fast and slippery. It is sure sign of the way he continues to evolve.

 For now, the questions is: What’s next? Gennady Golovkin was in Vegas and at ringside after announcing that he hired trainer Johnathon Banks, who succeeds Abel Sanchez. GGG is 0-1-1 against Canelo, both bouts controversial and both at T-Mobile.

The next date for Canelo to fight is in mid-September. Like Canelo, GGG has a  contract with DAZN, the streaming service that was expected to pay Canelo between $30 and $35 million for his victory over Jacobs.

 “One of the reasons Gennady chose the Zone (DAZN) was that it was the cleanest path to a third fight,’’ GGG promoter and manager Tom Loeffler said Saturday before opening bell.

 Canelo did say no to that possibility after his decision over Jacobs.

 “I’m just looking for the biggest challenge. That’s all I want,” said Canelo, who went on to say there was no lingering anger at GGG that might prevent the third step in a trilogy.  “No, for me, it’s over. But if the people want another fight, we’ll do it again, and I’ll beat him again.”

 Again, that’s business, the Canelo way. 

Golden Boy Promotions executive Eric Gomez called Vergil Ortiz Jr. “boxing’s best prospect” at a news conference. Hard to argue with that one. At least, it was Saturday night when Ortiz’ power did what nobody ever has: Knock out welterweight Mauricio Herrera.

A new look doesn’t make for a new fighter. But a new weight class might.

Lamont Roach wins unanimous decision over Oquendo 

Lamont Roach took punches and gave up points early. But he took control of the tempo and his future late, scoring a unanimous decision over experienced Puerto Rican Jonathon Oquendo in a victory that could be a stepping stone toward a major super-featherweight title.

It was an interim title. Aren’t they all? But John Ryder looked as if he might become a long-term champion.

Russian featherweight Aram Avagyan (9-0-1, 4 KOs) scored a second-round knockdown, scored with jabs, scored with combinations and scored with everything else he threw. Over 10 rounds, all of that scoring added up on cards that left Francisco Esparza (9-1-1, 3 KOs) of Las Vegas with a loss by unanimous decision. Esparza displayed resilience, climbing to his feet in the second with energy, but not much else in a futile attempt to slow down Avagyan in rhe second bout on the Canelo-Jacobs card..

Only echoes filled the arena. That might have been a good thing. Nobody saw the opening fight on a card featured by Canelo Alvarez and Daniel Jacobs for the middleweight title Saturday at T-Mobile Arena.

Las Vegas super-middleweight Alexis Espino (2-0, 1 KOs), a Robert Garcia-trained prospect, opened the show with a four-round unanimous decision over Billy Wagner  (1-1) of Great Falls, Mont. Wagner was left bloodied in a fight that began without him having any chance.
