On his American debut, Conor Benn smashed Brandon Sanudo inside two rounds to make a big statement on a great night in New York.

The 21-year-old welterweight walked into the room with Big Ben chiming and never looked like losing the fight. 

The 'Dark Destroyer' wasted no time, with his KO coming only 44 seconds into the second round.

Benn forced Sanudo into a corner, sending a jab into the Mexican boxer’s gloves, following it up with a hard right to the body, causing Sanudo to tuck up.

As you can see in the video below, Benn sensed blood, didn’t let up.

He threw a stray left which deflected over Sanudo’s shoulder, then went for the kill with a vicious right hook.

Sanudo evaded, ducking low.

As he straightened, Benn reigned in a killer body shot. Sanudo staggered; his mouth made a small O, air rushing out.

He hit the deck, more from pain than the momentum of the punch.

Conor Benn had announced himself to America with his arms aloft.

The win extends his record to 10-0, with eight knockouts. Some may have argued that the opportunity came too soon for Benn - he did only make his professional debut on the same card that Anthony Joshua became world champion on after all - but the Englishman proved them wrong.

His US debut, coming in his tenth fight, was a huge step. His father didn’t make the leap across the Atlantic until fight number 24, while Kell Brook took 24 and Anthony Joshua is still yet to make the trip.

"I really enjoyed it and got some reception here, so it's just a great experience so early in my career,” Benn told Sky Sports.

"To hit America and England is something special. It's really different.

"Here the way they do things is completely different and it will take a while to get used to it, but it is early doors and when it comes to the time to fight here - potentially for titles - I will know what I'm in for."

Benn is proving himself to be one of the most exciting fighters emerging through the ranks right now, with the Sanudo bout making it five consecutive matches where he has stopped his opponent within three rounds.
