Esham Pickering added the European super-bantamweight title to his collection in Bradford on Friday night.
Pickering was largely able to control the bout from the outside
The 27-year-old claimed his fourth stoppage win in a row, flooring rugged Italian Vincenzo Gigliotti with a short left hand to the temple in the 10th round.
Gigliotti was deemed unfit to continue despite beating the referee's count.
Pickering, who already holds the British and Commonwealth belts, said: "I have worked for eight years for this and it is all paying off now."
He added: "I have been through some bad experiences but it is all about patience and with my team behind me I believe I can go all the way."
Gigliotti had gone the distance in a WBA title fight in his last outing and attempted to break Pickering's poise right from the start.
But his crude swing lacked precision, allowing Pickering was largely able to control the bout from the outside.
Pickering's promoter, Jess Harding, believes the sky is now the limit for his fighter.
Harding said: "This is definitely Esham's time and he has turned his whole career around.
"We want to enjoy the European title now then we will have a think about where he goes with his other two.
"But I firmly believe that this is the launching pad for a successful career."
Pickering trained all the way through Christmas for the bout but will not be taking any time off for a belated break.
He said: "I will be back in the gym next week training hard."
