Brian Rose gained revenge against Carson Jones after digging deep for a wide points win in their rematch on Saturday.
The Blackpool man had suffered a controversial stoppage in their first fight in February and was forced to overcome another early scare on the way to victory with scores of 119-111 116-112 and 117-112 in Hull.
With a harsh lesson learned, Rose adopted more discipline in the opening round of the return bout, boxing crisply behind a high guard and he jolted Jones' head back with a short uppercut.
But Jones oozed menace as he stalked his opponent in the second and uncorked an uppercut which left Rose on unsteady legs.
Yet again, Rose was swiftly hauled into a firefight and fired back with a crisp right of his own before his nose was bloodied by another ferocious flurry from Jones.
Any tactical talk was ignored by both men as they continued to trade from close range in the third round and Jones appeared to edge the fourth with constant aggression, even catching Rose with a punch after the bell.
Stung by this illegal shot, Rose came out firing in the fifth as his right hand ripped through Jones' defences, and the Oklahoma man ate a steady stream of rights in the sixth.
Gradually, the fiery threat of Jones was being diminished by Rose's spearing jab, an accurate weapon, and his march forward became increasingly ponderous.
Into the ninth, Rose at last could utilise his slick skills and unloaded crisp combinations before skipping neatly out of range.
Jones was not prepared to plod through the final few rounds and briefly troubled Rose with a determined assault in the 10th, but Rose answered with a big right in the 11th.
There was still time for more drama in the last, with Rose determined to prove his mettle, and he called Jones on for a further damaging exchange which was cut short by the final bell.
