Derry middleweight John Duddy takes less than two minutes to see off Mexican opponent Juan Astorga.
Victorious John Duddy said he was heading straight back to the gym to prepare for his next fight after Saturday's win over Juan Astorga.
Duddy stopped the Mexican in the first round as he continued his comeback from the loss of his unbeaten professional record to Billy Lyell last April.
The win in New York earned him a fight on the Manny Pacquiao-Joshua Clottey undercard in Texas on 13 March.
"I ain't stopping this train now. I am looking forward to it," said Duddy.
John Duddy has been beaten just once in his professional career
"My manager Craig Hamilton will be working on my next opponent and, whoever it is, bring him on.
"I will be straight back into the gym on Monday."
The Northern Irish middleweight moved his professional record to 28-1 with the 18th knockout of his career after just one minute and 55 seconds of the opening round.
Watched by Top Rank president Bob Arum, Duddy secured his spot on the Pacquiao-Clottey WBO welterweight title card Arum is promoting after twice flooring the outclassed Astorga.
First Duddy forced the Mexican to take a knee after a straight right to the head brought a delayed reaction, and then moments later he delivered a left hook to the body that persuaded referee Wayne Kelly to wave the fight off.
"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," Duddy said.
"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."
