The Belfast lightweight, making his American debut, stopped Carlos Galindo in the third round of the opening bout of the big Matchroom DAZN show in Boston at the TD Garden.
Moving quickly, McComb now has four four-rounders under his belt and will soon move up in rounds as he chases domestic title fight.
In Galindo the European Games bronze medallist was faced with a game opponent coming into the bout off the back of an away corner upset.
Following a tricky start, McComb quickly worked out his opponent and began punishing the Peruvian, targeting the body and eventually forcing him down in the third.
The Turf Lodge southpaw described how this is the learning stage of my professional career and I was putting into practice what we had been doing in the gym and I did that but it took me a round or two to get into that. I listened to my corner and I got better as the fight went on.”
“He was trying to smother my work early on and I started quite slow. But once I got my distance right I started to work him to the body and started to break him up as we had been working on in the gym.”
“He was tough but I hit him with a few body shots and I hit him around the side so he would leave space down the middle. The third round I kept banging it up the middle and finally I got through.”
“It hurt him and I put him away. I knew I was hurting him to the body and he was feeling those shots. I wasn’t rushing anything and I was trying to work on stuff as well. I could have blown him out if I had wanted to.”
Already with a record that many year-long pros would be envious of, McComb is not sure of his short term plans.
What he is sure of, however, is his long term goal.
The 26-year-old ‘Public Nuisance’ outlined how “I will take a break for now and leave it to my management team to sort out my next move, so I will take a couple of days off and then get back into training.”
“That fight was just another training session for me and I will just keep working hard.”
“I am loving it and the aim is to be a world champion before the end of my career and that is what we are working on every day in the gym. That is my goal.”
