John Duddy has lost just one of his professional fights
John Duddy defeated Juan Astorga with a first-round knockout at Madison Square Garden in New York on Saturday night.
The fight lasted just one minute and 55 seconds and gave the Derry middleweight the 28th win of his career.
Referee Wayne Kelly intervened after Duddy had completely outclassed the Missouri-based Mexican.
Duddy's next fight will be on the undercard of the Manny Pacquiao/Joshua Clottey bill at Cowboys Stadium in Arlington, Texas on March 13.
The fight had barely started when Duddy threw a nice left hook that landed on Astorga, who looked nervous.
Shortly after, Duddy landed a straight right hand to his head.
After a delayed reaction, the Mexican took a knee and referee Wayne Kelly gave him a count.
Once he got up, Astorga's body language suggested that his fight was done.
And it was a couple of seconds later, when a perfect left hook to the body from Duddy put the Missouri-based Mexican down again.
Referee Wayne Kelly started his count but immediately waved off the fight, giving "The Derry Destroyer" the 28th and arguably easiest win of his professional career.
"I got him right on the temple you know, and with temple shots there is a delayed reaction. I was surprised to see him go down, but I did hit him flush and it was a nice short right hand," said Duddy after the fight.
Of the knockout punch, Duddy said that body shots were something that he had not been concentrating on in recent fights, but trainer Harry Keitt had encouraged him to go back to working on the body more.
"I hit him a couple of times to the body, and with that last left hook to the body I could hear the wind coming out of his lungs.
"It landed on the button, and once I saw him land on the canvas I knew he wasn't getting up again.
"I wish it has gone on longer but I was throwing my shots with a lot of determination."
