It was an exciting back-and-forth battle that fits its blockbuster status as Charlo and Castano traded jabs in the opening rounds.

There was nothing in the middle of the fight as fans pondered whether he could be headed for another draw.

But Charlo upped the ante in the seventh round and Castano failed to go with him as he paired a flurry of punches but somehow pushed forward.

Main Event commentator Ben Damon tweeted: “This is an exceptional fight! Brian Castano’s chin is not of this world! “

Charlo went for the kill in the tenth round and a brutal left hook to Castano’s temple was the decisive blow as the Argentine got stunned and fell to the canvas.

Castano barely survived the eight count on his feet, but only lasted a few seconds longer when another heavy throw from Charlo brought him down and the referee stopped the fight.

Charlo had the lead on all three judges’ scorecards (87-84, 88-83 and 89-82) at the time of his KO in the tenth round.

It was an emphatic achievement for the American, whose status as king of the 154-pound division was called into question after his tie with Castano.

Charlo now holds the IBF, WBA, WBC and WBO super welterweight belts.

He joins an illustrious roster with Bernard Hopkings, Jermain Taylor, Terence Crawford, Oleksandr Usyk, Josh Taylor and Canelo Alvarez as the only undisputed male champions in the era of the four belts.

Tim Tszyu is the mandatory challenger for the WBO world title and made no secret that Charlo would be his favorite opponent, in part because he’s a bigger name and has repeatedly sacked the Aussie.

The 27-year-old has repeatedly made it clear that he wants his next bout to be for a world title and has traveled to the United States to watch the bout from the front and watch Charlo and Castano in person.

“I hope Charlo wins, just because I would love to fight him and beat him,” Tszyu told Showtime before the fight.

He then tweeted after the fight: “Great battle and great victory for Charlo. Ready when you are @TwinCharlo.

Australian boxer Billy Dib tweeted: “Wow what a Charlo ending.

“Tim Tszyu is the mandatory challenger for the winner of this bout.”

“This is a legacy,” Charlo said after his win.

“This is something legendary. I am a legend. Thank God I’m not done, dog. I could go up to 160 (lbs) and see if I can do it again.

But the 31-year-old was shy when asked what he planned next in his boxing career.

“I don’t know what I’ll do next,” Charlo said.
