Jermall and Jermell Charlo have become the first twins in boxing history to hold world titles in the same weight class.
Jermall (24-0, 18KOs) retained his IBF super-welterweight world championship with a unanimous 12-round decision over former world champion Austin Trout in Las Vegas on Saturday nightt, while Jermell (28-0, 13KOs) earned the vacant WBC title by rallying from five points down to register an eighth-round knockout over John Jackson.
Born one minute apart with Jermall the oldest, the identical twins celebrated their 26th birthday last Thursday and did so in style.
Jermall stuck to his game plan and fought behind his jab, throwing 292 jabs and connecting at an 18 per cent clip.
"It wasn't a struggle, it was a great experience," said Charlo after his second successful title defence. "I want to thank God for allowing me and my twin brother to see this day. History.
"Austin is a hell of a fighter. He's a beast. This was my first time going 12, but it didn't matter because I knew I was in shape.
"My game plan was to execute with the jab. I knew he was going to try to stop me, but that didn't happen. There's no way you can tame a lion.
"It felt good because I knew my brother would get the job done. We belong on this level. We need these titles to get the big fights and we're going to keep these titles to keep rising.
"I changed my mind - we're going to stay right here (at 154). Making 154 pounds wasn't as bad as everyone made it out to be."
Trout was quick to praise the champion: "Hat's off to Jermall Charlo. He fought a hell of a fight.
"I felt like I did enough to win. They won't give me a close decision, so it's time to start taking these cats out. But I can't make excuses. I fought my ass off, Charlo fought his ass off and hats off to him.
"I'm going to live to fight another day. You're going to see me back. We're warriors out here.''
Two minutes into the eighth round, Jermell Charlo, trailing 69-64 on the three judges' scorecards, landed a perfect counter right hand to Jackson's left eye.
As Jackson dropped his guard to insure his mouthpiece was in place, Jermell connected with two more right hands that sent Jackson falling forward into his corner. Defenseless and seemingly out on his feet, referee Tony Weeks stepped in immediately and stopped it at 0:51.
"It's history," said Jermell. "We did it. A lot of fighters don't come out of Houston and we did it. We've been boxing for all of these years and it had to happen.
"I was behind. He was boxing, he was moving around a lot. That was unexpected of him. I thought he was going to come out to brawl. I had to make an adjustment and I did.
"When he started slowing down, I was able to catch him with a shot. I knew that if he could have continued he could have come back so I had to hit him."
While both were selective with their punches, throwing just 427 combined shots through eight and a half rounds, Jermell was the more accurate fighter. The new WBC champ landed 23 percent of his total punches, including 34 percent of his power shots against Jackson.
"It was a journey to get here," said Jackson, the WBC's No. 2 contender going in and son of former world champion Julian "The Hawk" Jackson.
"I feel like I was ahead and I came up short. He caught me with a punch and I was trying to fix my mouthpiece. Then he hit me and I was out. It hit me in the eye, but my mouthpiece was coming out. I was trying to push in my mouthpiece back in and he hit me. I knew where I was. It dazed me, but I wasn't knocked out.
"It's boxing. It was a great fight. I felt I was winning the fight, I got caught and that was it. I dedicated the fight to my dad and I hope I didn't let him down. I fell short. You win some and you lose some."
Top of the bill saw Erislandy Lara outpoint Vanes Martirosyan by scores of 116-111 twice and 115-112 to retain his WBA world super-welterweight title, with the challenger having a point deducted for a low blow in the 11th in a rematch of their May 2012 fight that ended in a technical draw.
Lara, 33, making his fourth title defence, said: "This is boxing, not baseball. Low blows and headbutts happen. I'm a very intelligent fighter and at no point did I feel this fight was going to be lost.
"My mother and kids are still there so it would be a great privilege to go fight in my native Cuba. Everything is possible in this world. I didn't think I'd be champion of the world and here I am.
"I want to tell Team Vanes thank you for giving me the rematch. I'm ready to fight anybody. I'd like to fight Canelo.
"The Charlo brothers are my teammates and having three of us going back as champions is a great thing."
Martirosyan, the aggressor throughout, disputed the decision.
"I was chasing him all night," he said. "I put on the pressure. I thought I did enough to win. That was not a low blow. Replays show the trunks were high.
"I never ducked anyone. No one wanted to fight Lara. I stepped up and fought him again. I'll fight anyone.
