Ryan Burnett won the IBF bantamweight title after producing a masterclass to defeat defending champion Lee Haskins via a farcical split decision.
The Northern Irishman, whose victory also justifies his billing as the long-term successor to Carl Frampton, responded to the significant increase in class with the finest performance and win of his promising career. The only blemish at Belfast's Odyssey Arena came when American judge Clark Sammartino inexplicably scored for Haskins.
Maintaining a consistent sharpness and work-rate, Burnett convincingly outboxed the proven 33-year-old, succeeding throughout with both the jab and right hand.
Concerns had existed that in Bristol's Haskins, a fighter as awkward as he has been under-appreciated, he had agreed to a thankless match-up too soon. He instead ensured an unexpectedly entertaining affair by largely dictating the range and pace of the fight from the opening round.
An accidental clash of heads in the second cut each fighter over the right eye, prompting further questions about the Haskins' greater experience, but Burnett, 25, instead used his speed and accuracy to impose himself.
A classy right hand at the start of the fourth round hurt the defending champion, and as the challenger's timing and confidence improved, and he defended himself with his instinctive head movement, he built a comfortable lead.
Another big right in the sixth sent Haskins to the canvas, and left him vulnerable to a stoppage as he over-reached with punches, but it took until the 10th before he again appeared at risk.
Burnett landed with further right hands, snapping back Haskins' head, and then after taking a left in the 11th, he responded with an assault to the body and a left-right combination that sent Haskins down again.
When he returned to his feet, the aggressive Burnett sought the knockout victory he was only denied by the round's end when the champion was left defenceless by the ropes.
Thirty-two years on from Belfast favourite Barry McGuigan winning his world title against Eusebio Pedroza, he then saw out the victory as the judges confirmed him a 119-107, 108-118, 119-107 winner. In doing so he also emulated Wayne McCullough, another world bantamweight from the city, in taking world honours in his 17th professional fight.
Paul Hyland Jr claimed the IBF European lightweight title in style as he earned a sensational first-round stoppage over Adam Dingsdale.
The Belfast star came out of the blocks firing and quickly had his opponent down on the canvas, before a relentless flurry of unanswered combinations saw the referee call an end to the fight.
The result sees Hyland Jr claim his maiden title as he continues his unbeaten streak in the pro ranks.
It had been presumed that this would be the toughest fight of Hyland Jr's career, but the home favourite flew out the blocks and quickly found his opponent cold.
Hyland Jr took no time in finding a home for his rangy, left hand and two successive hooks quickly stunned Dingsdale as the legs started to wobble.
The Kent man desperately looked to hold, but in failing to do so left himself open for a rapid succession of punches before dropping to the canvas.
Dingsdale returned to his feet, still stunned, and a relentless Hyland Jr again piled forward, acting ruthlessly as he landed several spiteful, unanswered combinations before the referee had rightfully seen enough.
Speaking after the fight, Hyland Jr said: "The first round, I caught him early and stepped on the gas before I took him out. I trained extremely hard in the gym for this fight and was ready to go ten tough rounds.
"Thanks to all the fans for coming and supporting me. I was a bit drained before my last fight and I didn't perform, I knew this would be different. I knew I had him hurt as soon as I saw his legs going.
"I want to fight for titles and push on. I want the British title as soon as possible."
James Tennyson claimed the WBA International super-featherweight title after a sixth round stoppage win over Ryan Doyle.
The bout started off evenly with both men standing in close quarters, exchanging jabs and uppercuts as neither fighter had to go looking for each other. However, a sharp right hand from Tennyson at the end of the session momentarily staggered Doyle to win him the opener.
The second round continued at a similar pace, with Doyle regularly switching to the southpaw stance, but another right hand from Tennyson had a visible impact on his legs again.
The 25-year-old Mancunian, who accepted the fight at short notice, showed tremendous heart throughout the fight and he troubled Tennyson in the third, landing an overhand right to hurt the Belfast man.
A positive fourth round from Doyle then followed as he continued to switch from head to body effectively.
The frantic pace of the contest seemed to be getting to Doyle, whose work started to slow by the halfway point under increased pressure from Tennyson.
A sustained assault from Tennyson bloodied the face of Doyle and he wearily returned to his corner at the end of the sixth.
Sensing the fight was heading one way, Doyle's cornermen signalled the end of the fight before the seventh, sparking celebrations from Tennyson.
There was earlier a victory for Cuba's talented Mike Perez, 31, who after over two years' inactivity, following a stoppage defeat by Alexander Povetkin at heavyweight, returned at cruiserweight to defeat Slovakia's little-known Viktor Biscak in only 29 seconds. Barely a punch had been exchanged when the out-of-shape, late replacement Biscak lost his balance amid an apparent leg injury that left him unable to continue.
Luke Watkins also won the vacant Irish cruiserweight title, convincingly stopping Ian Tims in the fourth round following a big right hand.
