Metro Radio Arena in Newcastle - Middleweight Chris Eubank Jr. dropped Stepan Horvath twice in round five before doing the same again in the next round to force an early finish and made it 16 wins out of 16 in the paid ranks.
Eubank, whose father Chris was his cornerman, has now set his sights on a title fight.
"I took this fight at three days notice so I had no preparartion - I was out partying all last weekend so to stop the guy was a decent performance," he said.
"You can't name me another prospect who would take a fight at three days notice - it shows how dedicated I am and how hard I'm working to achieve my goals.
"I came into the fight knowing I had to conserve energy but as the rounds went on I could feel his strength dying down and I knew I could start handling him the way I wanted to.
"Full credit to the guy who showed plenty of heart. I've hit fighters with shots like that in the gym, wearing 16oz gloves and a headguard and they've been out cold or wanting to stop the spar, so the fact he was coming back and still fighting is full credit to him.
"It's time to start making our way to the titles now. Boxing is a business and like all successful businesses there are steps and procedures you need to take in order to grow and grow effectively.
"But when the time comes I will fight for a title. And whoever has it will wish that they never had to fight me because I will be taking no prisoners."
Eubank senior said little to his son between rounds - but predicts he has a bright future.
"He knew what to do so there was no need for me to say anything. If this was an exam, there's no point in speaking while the exam is in progress because he has already done the revision," said the former world champion.
"Christoper is exciting, frightening, new and fresh - it's going to be a wonderful ride. His abilities are just so far above what is in the market place right now."
